Brake Caliper Slider Pin Grease - How Much is Too Much ?
Vložit
- čas přidán 16. 03. 2024
- What happens if you put too much grease on your brake caliper slider pins ?. In this video I grease the slider pins with different amounts of grease on the pins to see how each amount affects the operation of the pins. The caliper bracket I used for this demonstration used two identical pins with concave tips and three flat strips ground onto the shaft of each pin. This was only a basic bench test with one particular type of brake caliper pin and bracket and does not necessarily replicate what the brake caliper will do when operating under load in actual braking conditions. There are many different caliper pin designs and some of them also have rubber bushings installed on the shafts, so the results could be very different to the pins used in the video. I would recommend always using the correct amount of suitable, rubber-friendly caliper grease and avoid getting any grease on the tips of the slider pins or, if you do, wipe it off before reinstalling the pin.
This job can be carried out with the bracket still bolted to the vehicle, but I used a new caliper on the bench for clearer demonstration. NOTE: If you are lubricating pins that have been in use on your vehicle, you will need to clean out the old grease from the bores and clean the slider pins before applying new grease and re-installing them.
It is important to lubricate your brake caliper slide pins as failure to do so may cause them to stick or even completely seize up which could cause uneven wear of your brake pads. The car may appear to drive normally, but the pads will only be pushed onto the disc from the piston side. This will give reduced braking ability on one wheel, and wear out the pad on the piston side much faster. The pads could also stay stuck against the rotor which will build up heat in the brakes and wear your pads down even quicker. Thanks for watching. Please comment, like and subscribe !.

Sir this is one of the best how to videos made. No stupid music. Straight to the point great video work.
Thank you !
Well, looks like I need to redo all my brakes to fix that. Wish I had found your video BEFORE doing my brakes.
I finished redo right now 😊
Honestly prefer video guides like this, simple, straight to the point, and easy to follow. Hoping to see more from your channel!
Thanks for watching !
Clear, simple and well demonstrated. Thanks for not including some obnoxious music like so many others do.
You're welcome, thanks for watching !
У нас в России принято, "мало смазки не бывает", и поэтому каждый пытается в любую дырку забить её больше, полезное видео, благодарю🤝
Thanks for watching !
I always load up the grease on the heavy side and leave some on the tip - zero performance problems... and never had a pin seize. The pin does not bottom out, as it goes through caliper bracket first.
I knew about greasing the pins and I always do when I do my brakes, but never heard of these tips before. I’ll have to try it next time. Thanks.
Applying grease to pins seems to be an art that even few "professionals" discover.
Thank you. I knew there was a trick to it, just didn't know how to accomplish it.
Thanks for watching !
The most common mistake in any brake job. Anybody can pop rotors and pads in, but greasing pins, shims and contact points are seemingly an afterthought and usually cause warped rotors or uneven pad wear. I’ve been doing brakes for 25 years and even I took away a lesson from this video, which is to lube the cavity before installing the boot - very good idea in order not to gum up the boot.
Thanks for watching !
From my experience of greasing shims, all that brake dust and crap sticks to them, leading to more problems down the road, I have always done my own brake jobs never had a problem or a complaint from a customer
Maybe you don't anyway, but don't grease the entire shim, only the part wear the caliper ears touch the pad.
DIY is a real problem for even basic jobs because 99% of people don't have torque wrenches. You don't guess specs when it comes to your braking/suspension systems.. let alone putting threadlocker on the caliper bracket bolts. Greasing pads properly is the least of their worries
@@COBRO98Have you been at a garage? Most of the time they don't care about thing you mentioned. I think some hobbyists are more precise with the things you mentioned. At least i do. ;)
I live in Ontario Canada and that means salt on the roads and rust on your car. Sooner or later this salty water makes its way past the rubber boot, either at the pin interface or at the caliper bracket interface. To slow this water infiltration down I always put a bit of grease in the slot where the rubber bushing is going to seat and rotate the rubber to spread the grease and form a better seal. Once I started doing this (both ends of the seal) I haven't had any rusty pins.
same here in NY near Lake Ontario....clean and regrease every Fall and Spring seems to be the best bet....lack of driving during Covid was the worst!
I now understand that I have treated my rear brake caliper with too much grease loving and shall remove and clean off the excess. I could not understand why my pads would not grip the disk tightly and now I do. Thank you ever so much for the tutorial, much appreciated.
You're very welcome, thanks for watching
Once the caliper heats up, those bores get slightly larger and the excess grease will seep out of its captive areas unless the pins have rubber seals which some in fact do.. Great video..
Masterclass video, I thought I already knew what I needed when doing brakes but you’ve just taught me a whole new level. Many thanks
You're welcome, thanks for watching !
Set underrated video.
This is the FIRST video anyone should watch if you are starting to learn how to work on cars by doing a brake job.
Great video. BUT, I don't agree 100% with the thought of it being over greased. Sure the pin will not push all the way into the cavity... but, it does not need to. You have a boot for one, then also the pin typically needs o be pulled out a bit to mate with the bracket. I find that when I have "over greased" the pins, that they are are still free when I change pads, versus when not. I also use Sta-Lube brake/caliper grease and not silicon. I do agree you should not have is packed on the tip and preventing the pin from completely collapsing the boot, but if the boot collapses, then you are good. That is part of the reason for the flat spots on the pin, to allow the grease to make its way back out. If you have a the pins with the rubber bushings, then yes, I agree 100% with your video as it will not allow the grease to ride along the shaft.
Mechanic of 40yrs, I use copper slip on slides, not greese, good vid for amatures who wana now how to do the job 👍
The reason to use silicone grease on these pins are because petroleum based grease will cause those rubber pin bushings to swell up thereby causing those pins to seize in the bores and also those rubber boots to become soft and rip as it reacts to petroleum grease
It amazes me how often I miss obvious things. I have not once ever lubed a caliper slider pin, and to think I almost passed this video by. Appreciate the knowledge!
Thanks for watching !
You can honestly have grease on the tip, IF... you make sure you can fully bottom out the pin in the caliper bracket BY HAND and have full travel with it, any excess grease will be pushed out into the slide pin boot and can be removed with cloth if you have too much excess, i actually prefer to have a good coating on the inside of the boot because i've worked on many cars where moisture got inside the boot and rusted away the pin around the boot seals and ruined it, just dont fill the caliper bracket holes and boot full of grease and slap it on, that grease can and will escape through any means necessary. Keep in mind the grease is used for both lubrication AND rust prevention on the slide pin so you dont want to underuse it either.
Finally answered my questions about the different pins. My Toyota Rav 4 has the rubber bushing on the lead pin only. I replaced my pins cuz the existing ones had ripped boots and became severely stuck inside the hole. Once removed were caked with Dirty baked on crud. Hard as a rock. When I purchased a new set of pins, the bushing wasn't included and the autozone stores weren't aware of it at all. So I figured that toyota discontinued that part as problematic. However I also purchased a new set of 4 rubber boots, and the in the bag were 2 rubber bushings for the pins (Sold separately). So I cleanup the bracket and holes and all surfaces. Also painted calipers with red caliper paint. (Holes cleanup was extensive but thourogh and masked of for paint). When I use the clear lubricant I not realized that I noticed some resistance and didn't quite feel how I expected it to feel. But I I proceed to over grease all the pins.
I was just about to reinstall my brackets over the rotor, but saw this video and Was I Wrong and your video was perfect in explaining too much lube would have caused me major head aches down the road.
So I'm perfectly and completely informed how to install and with your instructions " DO IT RIGHT!!" And save my girlfriend hundreds and keep her happy with me too. I was about to make a tiny but huge mistake just like the previous mechanic did.
Great Video and very Informed.
Thank you Sooo Much!! 😊
You're very welcome, thanks for watching !
Probably the best video I have seen on the subject. Thanks!!!
You're very welcome, Thanks for watching !
Today i understand that how important the deep knowledge is ❤️
Just awesome video 👍
Thank you !
Тот случай, когда "очень хорошо" совсем не хорошо. Спасибо за видео!
Thanks for watching !
I only learnt about greasing the pins in the last few years (I'm 50) . I thought I was doing it right but now I know I was over greasing them. I had signs of this too. 🤦♂️ Now to fix my errors. Thanks
Thanks for watching !
Excellent and very helpful. I had an issue getting a pin out - I assumed rust ... but it was an air suction issue now that I have watched you video TY
Thanks for watching !
Another good tip for people that don't take care of their vehicles. Thanks
Thanks for watching!
Very helpful video. Some of the best tips around.
Thanks for watching !
Excellent video. This also applies to putting a bolt into a blind hole. Excess grease or gunk can hydrolock the bolt, breaking the threaded hole. Just spray some brake clean into holes and blow them out with compressed air to avoid this.
Nice video. Also the thicker the grease the more likely to create vacuum. When i finish installing the caliper i lift the rubber boot with a screwdriver and sometimes it burps some air left.
Thanks !, good tip 👍
Excellent video. Very thorough and helpful. Thanks you saved me money !
You're welcome !
Awesome video! Silence is golden.
Thanks for watching !
I dont know why this crossed my path? I am working on my breaks currently , i guess we are always being watched..
If something is free for you to use, YOU are the product.
Big brother is just helping out
Excellent video on this subject! 100% perfect! Thank you!!👍
Thank you !
My respects buddy, great video keep them coming.
Thanks, will do!
Just lubed my caliper slides today! Didn't know if I put too much or little.
I always use Molybdenum Disulphide grease, commonly called Molyslip or CV grease, on the slider pins.
It's rated much higher than silicone grease for pressure, is kind to rubber, sticks to metals and is extremely water resistant. I have never once had a slider pin seize with Molyslip.
If it's good enough to cope with the severe load conditions inside a driveshaft CV joint, then it's easily up to the task of lubricating and protecting a slider pin.
One thing I will recommend is never to use copper grease. It is an abrasive that will wear through steel, causing the slider pin holes and the rubber boots to wear unevenly.
I re do it twice a year, always when I swap summer to winter tires and vice versa. I do always a break job, take the pins and pads off, clean them with break cleaner, some sand paper and break clean again and finally relube them. And always sand the inner and outer brakedisc surface, as well as the inner rim surface and bearing hub, I slightly grease them too with break grease same Inuse for the pins. Especially as pre winter treatment because of the salt.
very detail & super useful info. Keep it up
Thank you !

Thank you very much for this useful information..
You're welcome, thanks for watching !
New subscribe from this video. Best one I've seen on this topic
Thank you !
learned a lot from this. Thanks
Thanks for watching !
Worth checking on any new caliper or caliper bracket. Some come pre greased, some don't, I've even had pins seized in new brackets right out of the box.
Thank you soo for for this video. It's a well needed video for me. I needed that today bcz I'm about to do my brakes soon. I did some brakes before and over greased and had soo many issues.
Thank you soo very much.
Just like and subscribed the channel and waiting to see more great tips like this one.
Also a small recommendation that if you talk while explaining thing, that will be awesome 👌
Appreciate your video
Some how i feel this video was inspired by ETCG brake videos he did back in 2010’s
Not sure I agree, but those older ETCG videos was great. Loved the channel back then and watched all of it.
I usually check if it's too much grease by installing the pin and boot and see if the boot can push the pins back up smoothly when I press down the pin and let it go.
Applying a thin layer of grease caused it to stick again on the next interval..
Very long, but very useful 👍
Wow. Great video. Noting but informative.
Thanks for watching !
Good to know! I liked the video 👍
Thanks! 👍
Thanks!
Thank you for your support, I appreciate it ! 👍👍
😆🤡
excellent video ! 10/10
Thank you !
very informative. I'd like to see different style pins (rubber on the tip especially) with different clearance guides tested for more conclusive results. I have one problem with your claim that the pin not pushing in all the way could be the reason for uneven wear... The floating caliper is designed to retract those pins in operation not to push them in. Plus the forces involved are so high I doubt the grease will stop it or disturb it's operation in any meaningful way as opposed to just getting pumped out thru the clearance ways. If you can point to a specific situation where it would be a problem we could discus this but from what I understand as a technician if the caliper piston is in working condition the fact that you put too much grease in the pin holes should not matter in the context of even wear even if you have completely new rotors and pads. Please point out the holes in my logic so I can learn.
Thank you!
You're welcome!
Good advice here, and I'm glad I watched the video. One question though - doesn't the boot prevent the pin from moving all the way in anyway?
Remember guys keep your tip clean.
No way.
This makes too much sense.
Excellent
Thanks
That silicone grease will be gone out of there within 2-3 months. I'd use ceramic brake grease in there, personally.
GOOD STUFF THANKS
You're welcome !
Gracias❤
You're welcome
Can it be used for bosch superfit car brake calipers? I would be happy if you help
Okay. Question: taking into account that the brake caliper is mounted through those pins and the bolts to the brackets bores, how to prevent the pins from tilting after tightening the bolts? My conern is that if the contact surfaces between brake caliper and the heads of the pins are not perpendicular to the axis of the pins, then - in my opinion - it might cause the angular tension in each of those two bores so the brake caliper will not be able to slide freely. What do you think? Is that issue even possible or I am exaggarating? Currently I'm struggling with "sticky" front brakes in my car and trying to know the reason. Sorry for my english.
The pin never bottoms out on the caliper carrier during normal operation anyway.
Hello good job 😘😘😘
Thank you !
would be nice to see:
- how can you remove an extra greese
- how can you check if ping works correctly or you need replacement
If i can push the pin in by hand multiple times amd it pushes itself back just a little, its good! Thats my go-to atleast
What about the bellows? I really don't like when they have a vacuum inside them and are sucking inward. I usually open one end with a dull pick to squeeze out any excess grease and let air back in. When they have this negative air pressure, they don't want to open up as smoothly.
Good to show, factory lube way much less or grease or you could say nearly none at all, a smear..boot is there keep moisture/debris out can say to..
Thank you never knew that:)
Thanks for watching !
Great video quick question would that be the reason the steering wheel has a little shake in it and pulsating from high speed to low speed and I pulls to the left of right could that be the pins or calibers itself
It's unlikely to be caused by this. This link shows the main reasons you get steering wheel wobble: www.theaa.com/breakdown-cover/advice/steering-wheel-shaking
I just drill into the bracket and thread in a zerk fitting. Couple pumps of ep grease and good to go.
Thank you for sharing this video..
I wonder do you have experience with smaller brake caliper like on the honda cub bike, one of the pin was not inside the metal bracket, it was only rubber boot..
the problem i have is when i pushed the bike towards, there is no resistance at all, however when i pull the bike backward and also tilt the handle i feel so much resistance from the brake pad..
does the silicone grease is a must ?? can i use generic grease to lubricatet the pin ?
I don't have any experience with bike calipers at all I'm afraid. As for the grease, I would recommend using a good high temperature silicone grease like in the video. Other greases can react with rubber parts and cause problems.
@@screwsnutsandbolts Thank you so much for your reply.. I'll try to use silicone grease then.. again thank you so much, and have a great day..
They work the same with rubber boot installed
When I did my own breaks this one part is the most annoying, I found the pins would bind with too much grease but too little and I could hear metal on metal scraping, super annoying to try and get it right.
Love your video. I need to repair my rear brake, this video will give me some idea what to be careful about. Well done.
Thanks! 👍
Only 1 of 8 was stuck, not bad for 18 year old car. But in Australia , no salt ,the cars last.😅
Would you say that silocone grease (or 'paste' as I've seen it) is recommended over a black synthetic grease?
Yes a high temp silicone grease is recommended
I silicon all pins
Dude I'm not here to say this is not the right or wrong way but if you ask any certified trained or ASE technician they'll tell you there is almost no wrong or right way to grease the pin. I work at a few dealership and we just spread the grease on the pin and some will pack a little grease inside the caliper and on the pin and call it a day. Never had any issue or hear of any in the years I worked at the dealership.
we use antisieze instead of grease. it lasts longer and will repel water and take the load.
I’m re-doing mine now and that stuff dried up…gonna use some form of grease this time
Спасибо.
You're welcome !
Much thanx dude. Do you know, what is the difference between pin types, like Pin A and Pin B on many brake calipers? Pin A has notch like in your video and Pin B doesnt. For example, Honda's brakes has A and B markup on their BC, but on the right side A mark is on the top and vice versa on the left side (bottom). And i dont know what is the right way how to place pins
Thanks. I'm not sure, it seems to differ between manufacturers. This link may be of help: www.civicx.com/forum/threads/help-front-brake-guide-pins-top-bottom.48762/
remember! Always wipe the tip.
Very thin coating on the pins. That's it. No grease anywhere else. Grease collects dirt ! Wire brush ftw
"and the Woe masters teach the deepest secrets"....
Thanks for the great vid!
Thanks for watching !
Yep, I've done that before.🤦♂
How would i clean out the bore if i put too much grease on the pin? A Pipe cleaner and a lot of brake cleaner i would assume no?
Yes that would do it, just make sure you don't leave any debris in the bore
Bremsystem erzeugt bei Normalbremsungen ca. 15-25 bar und bei Blockierbremsungen ca. 120-150 bar zu viel fett spielt dann keine rolle, wenn du mit finger die Führungbolzen zürickziehen kannst dann die nicht komplett gerade "schwimmende" Bremsscheibe druckt ohne probleme die Bolzen irgendwann wieder zurück
I’m noticing my brakes squeaking but my vehicle is brand new(6 months in), could it just be accumulated brake dust or something else ?
Were the brakes bedded in from new ?. This may be worth a try: www.wagnerbrake.com/technical/technical-tips/break-in.html
Is it safe to remove the rubber bushing if they are obstructing the movement of the pin. I'm talking about 12 years old car not new
I can't really advise one way or the other to be honest. If they're obstructing the slide pin they've probably swollen up for some reason. I'd replace them if possible as they're there for a reason. I've heard some people say they've removed them and it made no difference to the braking performance, or the vibration level. Have you seen this link: blog.1aauto.com/what-does-the-sleeve-on-the-lower-brake-caliper-bolt-actually-do/
To the point
Thanks for watching !
No lube on the tip. Got it
funny.lol
No such thing! As long as the boots can hold it, it gets globbed! I'm partially joking, but for real up here where these pins love to rust like crazy, a lot of lube and a good seal is essential.
