To clean your pads and eliminate squealing, clean them with acetone and a rag. Do this two or three times until the glaze and discoloration is gone. I've been doing this on my DuraAce Di2 bikes for the past 6 years and it works like a charm.
I use a cheap propane torch from the local hardware store to burn-off contaminants from my brake pads. Using liquid cleaners to clean pads just pushes the contaminates into the pad.
Loving your channel, Jon. Two thumbs-up on your enthusiastic willingness to experiment to address subscriber's questions. I think I need to clean and lube my bike more frequently ...
I use MEK solvent to clean metal. It's better than Brake Cleaning solvents. Just don't get it on painted surfaces. People say once you get oil on the pads they are toast but that is not true if you clean them with MEK.
My rear brake got contaminated with brake fluid and had the same squeal. Sanded the pad and it did nothing. My dentist who is an avid cyclist said give them to me. He sand blasted them with a dental sand blaster. I sanded them a bit more and scuffed the rotor with 220 grit. It worked.
I accidentally spilled brake fluid on my mtb rotor and eventually contaminating the pads. i tried a degreaser, didn’t work, tried alcohol, didn’t work, I tried burning the pads, still squealed, it was RIP to the pads 😅
You can try to submerged the contaminated pad in IPA for 2 minutes and dry, it usually works for me. If it didnt work, try burning them on gas stove for 20s, let it cool down, then dump it on IPA again and dry.
Wd40 from muc off is great to f up you're brakes. Was lubing my spring and pulley wheels on my rear deraillieur and got on my rotors, went for a ride and no brakepower. Cleaned it and had to sand my rotors and Pads to grip again .
While the whole world experiences stockouts of L03A pads, Jon messes up with them 🤣 jokes aside, great stuff, and as usual thanks for your work and the content!
Great test. I have terrible brake squeal problems despite being meticulous in cleaning and not touching rotors. Cleaning with alcohol makes the problem worse, big descents dragging brakes temporarily fixes them. They are new pads as well so reluctant to trash them.
Excellent. Dumb question, why would you spray your bike with silicone in the first place? Automotive spray wax works great. Doesn't the silicone leave a Oily film?
Would've been interesting to see if a degreaser or GT85 type spray also effected the braking as it's easy to spray on rotors when cleaning with those products... not sure how many of us would put lube from a bottle on our rotors🤣. Thanks for the content though man.
you have to do some videos on bike maintenance and small stuff that everyone can do, like changing brake pads, cables, brake oil flash....etc. share some of that experience:)
I presently have 6600 miles on my chain and still show less than 0.5 wear . Properly cleaned on a regular bases. For the first 3300 miles I used an oil base lube and then switched over to waxing . Now I am wondering hon many miles the chain will last . Cleaning works .
Waxing is the way to go. Prolongs chain life considerably, which also prolongs your cassette, chainrings, and jockey wheels. Less maintenance because wax does not attract dirt. The whole process is fairly easy to do.
This is a perfect response to the rude dude that thinks a miniscule trace of Heptamethyltrisiloxane in the snow making is enough to do in the brakes. Hooray for empirical evidence.
A simple chain wear tool is a great investment. I admit I only change my chain when it's worn enough. But I can get many years out of cassettes and chain rings with consistent cleaning of at least my drivetrain. Great simple video to demonstrate the danger of cross contamination.
Going to ask as I didn't see in most of the comments, did you bed the brakes in first then test? or were they just raw each time? But yes the sound, i hate that sound on my discs took a new set of pads, not sure what they were contaminated with but sandpaper helped.....
I have changed pads 4 times in less than a year and cleaned rotors with alcohol. Bedded brakes in everything and keep all lubes well away from rotors. Within 2 weeks I get mental screeching and hardly any stopping power. It's embarrassing! Mechanic bled the brakes and cleaned them up as well. They are 105 disc calipers and I have heard that they can leak. What can I do?
Great video. Nice comparisons. What about the chains on an indoor trainer. I have a dedicated bike on a Wahoo Kickr and have logged about 8000kms. The chain does not get dirty but what about regular wear and tear?
You’re crazy lol! And I just used the chain checker (that cost like 2 quid from Amazon) yesterday after noticing some noise, new chain on today. Can’t believe how long the old one had gotten!
Rim brakes as comparision would habe been interesting. Your examples of breaking with front disc seemed before and after horrible Bad for me. But thank you for Real life testing! Additional think of 100kg sitting on such bad brakes.
Looks like silicone is no match for disk breaks. I'm kicking myself for getting rim breaks for my new bike. I've never used carbon wheels before and they terrify me when I go dow steep decent and have to stop or make a sharp turn at the bottom.
Very interesting, some kinds of silicone oils are intended to use for car's cam belt to prevent from slipping at pulleys, so they are increasing friction. Also, since I start waxing my chains last year, they have immeasurable amount of wear (Also many rainy rides), one chain have 5000km and second have 8000km, I'm swaping them two times a week.
Cool video. I'm surprised how well the brakes performed with silicon spray on the rotor. I thought it would be much worse. I'm shocked you use an impact driver to do up your through bolt. Those things put out 100+ Nm of torque.
Man, just using these L03A pads knowing you might potentially render them unusable feels so awkward. Where I live you are lucky if you can even find them in stock. At three times the usual price...
Wait - you don't have a trainer? Does this mean you are heading south for the winter, soon? It has got to be getting cold up there in western Ontario! :-)
If you get contamination on your brakes and they squeal like in your demo all you need is some CRC De Squeak from your local auto part store. Works every time. Why pay a shop or spend a hour or more trying to clean with alcohol. You will need to clean some of the excess off after then brakes start to work properly because it's a bit messy. Honestly, if I could get smaller cans of this spray and relabel it I could make a fortune off you cyclists. You people spend crazy amounts of money on cycling crap.

Love it. I had already given this a thumbs up 1 minute in. I was one of the comments concerned about contaminating rotors. Well done Jon
thank you!!
We, the cycling community, are grateful for your sacrifice
LOL np
I was thinking the same thing! Great video!
Fun video man!!! Loved watching it good work :)
thanks so much

Thanks a lot for making this VDO. It does help clear things up for me. Ive had squealing brakes before but didn't know what caused it.
thanks, glad you enjoyed!

LOL np!
Shimano brake fluid has a similar effect to the chain lube. As I found when my calipers started leaking!
thanks for sharing

Fun video, little science experiments like that are entertaining. The noise lol Not sure what else you could try, maybe a psi test
thanks
thanks mate! i learned a lot today

Unfortunately there are people I know who don’t maintain their bikes often…🙀
Thanks for sharing bro.
Ride safe and keep the rubber on the ground…
thanks, same to you!
Kudos for listening to the audience and testing it out! Coming back to Clermont anytime soon?
Thanks so much! I will be back next year, I love it there!

great stuff!, have you ever consider having a series for bike maintenance??
Yes!! I am going to do this for sure!!!
Great video. I’d be interested to see the effect of brake cleaner used before trying to brake as well as after the squeal starts. Nice mustache!
Lol. Thx. I will try this
Thanks Jon. Brilliant testing.

Yes, I did 3 runs down the hill braking to bed in the pads for each set of pads
it would be easier if you just put oil into the caliper and pads.
Nice

Sounds like something is leaking onto the pads/rotors
@Jon Maloney Cycling Its almost put me off of riding the bike. Makes me go potty!
Can you do a video on cleaning etc
I will for sure, stay tuned
Great stuff as always. Keep up the great work. Enjoy watching your videos.
thanks so much, appreciate it!
Great content Jon. That was very original and fun to watch and learn through your effort.
thank you
@@jonmaloneycycling7593 Worst idea ever .dude u never put lube or oil on ur brake pads .
Great video. Nice comparisons. What about the chains on an indoor trainer. I have a dedicated bike on a Wahoo Kickr and have logged about 8000kms. The chain does not get dirty but what about regular wear and tear?
Thx man! Yes chain inside would last a lot longer because there is no dirt, I would buy a chain checker and see if it needs to be replaced
You’re crazy lol! And I just used the chain checker (that cost like 2 quid from Amazon) yesterday after noticing some noise, new chain on today. Can’t believe how long the old one had gotten!
LOL yep!!
I use a similar spray on my frame and other areas but I just spray it onto a soft rag and wipe it on, that way it only goes where I want it to.
true!!
you single handed clear out all the duraace supply...
LOL
Dude you live in such a nice area
thank you
excellent video
thank you
Thanks for taking one for the team, the clean up and swapping out was prob a pain. Aloha 🤙
thank you!
Great content! Keep it up Jon!
thank you
Such a good experiment! I vote the bikes are trash at this point. You can send those to me.... hahah!
LOL!!!

But thank you for Real life testing!
Additional think of 100kg sitting on such bad brakes.
thanks for the feedback!
Make a cleaning video next!
great idea, will do!
That was crazy!
Fair play Jon, serious amout if hassle doing that!! #savetherimbrake 🤣😉
LOL
Looks like silicone is no match for disk breaks. I'm kicking myself for getting rim breaks for my new bike. I've never used carbon wheels before and they terrify me when I go dow steep decent and have to stop or make a sharp turn at the bottom.
I use ceramic detail spray every time after I wash my bike. Water and dirt come right off.
Nice

What’s your post ride clean up like? Keep up the great content!
Thx man, I will do a video on this for sure
Great video! Way to put the naysayers to rest Jon with facts. You should start maybe a video series with different experiments and testing them.
Lol good idea
Will you still use silicone spray on your bike
For sure
you need to thank us for giving you video ideas.
Hahaha. I actually LOL when I saw your comment, and yes I do. Thank you
I am interested what's in that safe tho
LOL
00:23 my comment made it in your vid hahaha
LOL 👍
Great video - you got a new subscriber. I'm a 'drive train cleaner' too...!
awesome, thank you!!
this is metal pads or resin?
They are resin pads
Cool video. I'm surprised how well the brakes performed with silicon spray on the rotor. I thought it would be much worse. I'm shocked you use an impact driver to do up your through bolt. Those things put out 100+ Nm of torque.
thanks, glad you enjoyed
Such a cool idea for a video! I cant even get my hands on the Shimano finned resin pads 🥲
thank you
Nice Bro Science Bro ,approved👍
thank you
Thanks mate good to no.
thanks for tuning in
I enjoy a lot ur science 😄 experiment videos 😎
thanks!!
Man, just using these L03A pads knowing you might potentially render them unusable feels so awkward. Where I live you are lucky if you can even find them in stock. At three times the usual price...
Were you only pulling the front brake?
Yes of course
try to burn the contaminated pad for 5mins.
thanks for the comment
9:32 man puts oil on brakes and is surprised he can’t stop
LOL
Wait - you don't have a trainer? Does this mean you are heading south for the winter, soon? It has got to be getting cold up there in western Ontario! :-)
Doesnt he race on zwift? Maybe borrowed
@@misterdapper754 Yeah, I believe you are correct. Maybe I misheard Jon in the video.
Sorry guys I meant a traditional trainer that spins the rear wheel so I could test the brakes. I Habra a kickr
Soooo..... You wanna sell me that sexy CAAD12 Ultegra on the wall there buds?
LOL
@@jonmaloneycycling7593 damn 😑 *long sighs* Guess I'll just keep on looking than eh

wow, great response to getting roasted in the comments. really useful video.
thanks!!
When I saw u pray that in your video the other day I cringed so much coming from someone who owns the same bike 😂🥵
LOL yeah I don't think you were the only one
You're a bike mechanic for 8 years but you makes mistakes by cutting the fork tube wrongly 🤣
When
Lol
