You put one of the old brake pads for the piston to blow out against. 😊
I start with both, just to keep things controlled
Omg we make dollars not sense 😂
@@auk7150 Well, ok look at the labor time to rebuild a caliper, & the markup on a reman caliper. What works to your advantage? Sometimes you might be surprised.
@@user-mx7xd4pk5h I’m for rebuild and acknowledge the point , but why not use the old pad , what’s the point of creating a more dangerous work environment ..
@@auk7150 Well, the object of this video is to not put your hand on the piston & blow it out with air. But if you are going to use air, you want the piston to come completely out, or I do, it is all to speed up the dissemble of the caliper. Sure, put a towel over it. Safest thing is to get reman calipers, so you don't dissemble them. It is ok for a doit yourselfer, but for a garage, it makes more sense to replace them, & rotors.
Small block of wood wrapped in a shop rag is what you needed
Tobey Maguire saves the day again!
👍👍👍
He'll put some dirt in your eye, atleast his eyes are covered 😂😂😂
I’ve always just used a small board never had any issues
Dang right🎉🎉
Or put your hand there to slow it down. That's why you got 2 of them.
I learnt this the hard way😢
I lost this tip if my finger in a pneumatic clamp whilst working as a machinist when I was 18. Air and hydraulics are very powerful and won’t bat an eye at body part they will go through it.
I used to be a apprentice machinist and I remember holding my finger in the chuck and almost pressing the pedal to see how tight it would feel, I was one iq point away from turning my finger into mush.
Thank you for the advice!! I’m about to do a brake caliper repair, I’d probably hurt myself!
Just fold up a rag like every decent tech has actually done
Try a 2x4
What he said 2 / 4, but we no longer rebuild them. We just buy them rebuilt.
El video es de lo más explícito!!! Jamás poner la mano al tratar de sacar el pistón de la pinza de freno usando aire comprimido....hay que poner un taco de madera que amortigue el impacto de su salida. Muy buen video que ayudará a no cometer un grave error.
Saludos desde Santa fe, Argentina.
Bienvenido. Gracias por calificar el video. Hola a ti también desde Kyiv, Ucrania.
I had to watch it twice to see, that this was a pencil and not a hex 😂
i like how he was already prepared with the safety goggles on, he knew what was coming.
Tony hawk’s a mechanic now 😂😂😂😂
Quad piston calipers are always fun.
Piece of 2x4 usually works well…or 1x2 on smaller calipers.
Use fluid pressure to slowly push the piston out.
Good explain !!!
Thanks a lot
On a different multiverse, spiderman was a mechanic.
Would check out since it's a form of engineering.
Why is Tobey Maguire breaking things with my break calipers 😂
Я обычно ветошь кладу , и удар гасит и не вылетает
А не проще убавить давление. Недавно вот только менял поршень, ставил 2 бара и чуть нажимал на пистолет, и поршень не превращался в пулю
Best to wrap cloth around it to both capture the piston and any mist and brake fluid also to dampen the piston from hitting the other side.
You don’t need so much pressure. Just enough to get the piston moving.
For many many years I simply wrap the caliper with a shop towel and it will catch it.
2x4 works great
tried my fingers once. only did it once…
That's good to do it immersed in a bucket with water... so it doesn't bounce around and can hurt someone...
Оппа, спасибо, вы сохранили мне пару лучевых, планирую пойти в ученики автомеханика
I have a hand pump that is made to calibrate pressure gauges up to 600 PSI. One piston took 400 PSI to pop out.
We used a piece of wood so you don't scratch or ding the piston.
Maybe turn the pressure regulator on your air compressor down a little.
That's good advice. Thx.
You're welcome
Я брал очиститель карбюратора и надевал уплотнитель. И он потихоньку выходит . на месте приора
Well, that’s one way to get 6 weeks vacation. It’ll be a painful 6 weeks though.
Try not blast the air through and control it slowly and you don’t need half your tool kit to catch the break cylinder .
Simply clever
I use to pack a rag in front with caliper facing down and slowly let air in and it didnt hit the deck.😊. I just buy new ones now..
Good demonstration, good warning. Also I like that bench vise, looks good and solid.
Thanks a lot
Yeah it does that when you cant regulate the pressure. You might need 20 to 30 psi to get one to move out in a controlled but not forceful manner. Makes a pop but doesnt harm anything. I wrap a couple rags around it so the piston doesnt get damaged.
Surprisingly, you can also use a bike pump if you don't have an air compressor. But definitely use a block of wood to stop the piston from flying.
Tobey Spiderman should grab it 😅 .
Or, or, hear me out.... push the piston out bfore detatching the brake line. So break line free, snug it up, press brake pedal, remove line and pison using your hands so nothing gets damaged and no one gets hurt.
Wow I see alot of people have gotten hurt because you use to much air pressure and don't use a sponge to reduce the piston to hit and come out fast just saying I did this for years and never got hurt in my 35yrs experience
Good advice
Thank you
make the air pressure less??😅😅😅
Yes, you can reduce the pressure, but you need to control this process
@@opelservicekyiv какой процесс? Надо контролировать? Давление?
@@samsungsamsung-qc5uu давление. Можно легонько нажать придерживая, а можно на полную и вылетит так что потом и не найти
@@opelservicekyiv ну это и козе,понятно
You can buy a small hydraulic cylinder to do this with a pipe adaptor , use a block of wood between the piston and the caliper body to save damage
That's funny. I built one years ago out of an old Electroglide front brake master, a chunk of handle bar and a steel plate base. With a flexible brakeline with adapter fittings on the end. Use it for bench work on all sorts of cylinders. It will nicely blow apart most calipers.
Have fun.
When did Toby Maguire become a mechanic 😂
Try turning down the air pressure
“Let me borrow your pencil real quick”
👍😀
Just use the brake fluid pressure to get it almost all the way out. Then you can remove the caliper and pull the piston.
R u sure thats the easiest way and safe? Thanks for the advice
I showed this as a precaution to avoid damaging my fingers. Using high air pressure to install the piston seal can cause injury to your fingers.
I wouldn’t want to break my pencil!
This is why I have a hand pump with swappable fittings in the shop 😂
Don’t shoot air into your caliper when your fingers are in there, good advice, I don’t know how you’d accomplish that anyway
Use a bit of suitable flat steel bar instead
Thanks 👍
Good thing our hands aren't made out of pencils!
Shot one through my shed, almost going through the walls😂
And half an hour to find the pieces!
Wood works great
Yeah because I'm always shooting air thorough brake cylinder when I'm working on it😊
Try bike tyre tube. Reusable and less mess cut to length
Maybe don’t use full pressure when doing that instead.
Dont use compressed air on brakes. Use a grease nipple in the place for brake pipe and use a greasegun to taje out the piston safe and unhurt. Its only fools that use air but the greasegun have usually about 600 kg / squere cm in presure. I start with that when i shot my cap of ny haed with the piston.😮 work safely😊
I just hold my hand over it and let it hit the end and pick it up. Never failed.
Use a hockey puck it won’t damage the piston
Oh.... I would never have thought of putting a pencil there in the first place.
Because it's a stupid idea
I use a piece of wood. I cracked a ceramic piston with the pad
Use one of the old brake pads
looks good advice to me. Salute from England! 👍🍺🇬🇧
We salute you too, thank you😊👍
Very good call! Easy way to lose a finger.
You change air pistol quick haha
I keep a 3in 2x4 for it.
A longer piece of 2x and hold the end and nothing to chase and pick up👍
His spidey senses were tingling
Nobody ever uses safety goggles in real life 😂
They forget, but you have to wear glasses 😊
I broke my finger doing this, a painful lesson!
Most good techs have pcs of 2by in all sizes, and then you can ease into the pressure inst3ad of full throttling the shop air
I wear a ww2 era navy divers rig when I do mine.
Unless it’s a rare or collector car it’s easier to just buy rebuilt lol
Use the brake pedal on the car. Before disconnecting.
Unless you shop at The Bone Yard.
This might not have come off my car it might be a used one I'm rebuilding.
None the less, you don't need 150 pounds all at once. A bleed valve on the airline will allow this to come apart real smooth without any drama. Our shop specializes in the older stuff. We do a lot of parts refab.
Have fun.
The one and only time I'll accept a finger wag 😂
Push with hydraulic, not pneumatic.
No body repairs them we just replace them nowadays
😂😂😂breaks a pencil every time 😂😂😂😂
I lost a finger nail like that 😅
Ive seen the results of using something fleshy to stop a brake piston
Block of wood is easier than trying to find the socket you sent to orbit.
I always just put a piece of 2x4 in there
Да, и пальцы попалам, мы обычно молоток ставим и выдавливаем в основном на месте.
попал палец месяц назад, чуть не отрубило. болит ещё 😂
I use a small piece of 2x4
Video: *demostrating something*
Mind: this guy looks like spiderman
I hold it before it take speed . Now there's tool everywhere on the floor .
I know someone that really did this!
When i tried it, air didnt do anything. I had to attach a grease hand pump and pump em out
Learned that the hard way😅 dont try that at home😂
People shove a shop rag there all bunched up. its safer and catched the piston with no mess
Вот именно - я себе так знатно палец прищемил - чуть не сломал. Поршень, зараза, не выходил - клинило , пришлось крутить щипцами и по-разному, вот он в итоге и выстрелил чуть мизинец не снес.
Just put a rag in and done use full power from the airline. I do it, not had any issues.
Is that the air line 3000 😂😂
Un gran ejemplo y una gran lección para aquellos te quieren hacer los rápido y fácil
Estoy de acuerdo, hay que tener cuidado
Hollywood actor Jeremy Renner becomes a Auto mechanic😅😅😅😅
very similar
