You put one of the old brake pads for the piston to blow out against. 😊

@auk7150 7 дней назад

@@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 ..

@user-mx7xd4pk5h 7 дней назад

@@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.

@resinductelec 9 дней назад

For many many years I simply wrap the caliper with a shop towel and it will catch it.

@1985230ce 17 дней назад

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.

@1985230ce 17 дней назад

I have a hand pump that is made to calibrate pressure gauges up to 600 PSI. One piston took 400 PSI to pop out.

@fredrickmiller5165 4 дня назад

We used a piece of wood so you don't scratch or ding the piston.

@Jack-jw3rd 17 дней назад

2x4 works great tried my fingers once. only did it once…

@stevieboy7873 16 дней назад

Try not blast the air through and control it slowly and you don’t need half your tool kit to catch the break cylinder .

@Subiturbobahiense 3 дня назад

That's good to do it immersed in a bucket with water... so it doesn't bounce around and can hurt someone...

@raiderjohn9407 9 дней назад

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.

@user-ju5hb7fh1c 16 дней назад

i like how he was already prepared with the safety goggles on, he knew what was coming.

@hernansalas4133 16 дней назад

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.

@andrewwilson8317 15 дней назад

You don’t need so much pressure. Just enough to get the piston moving.

@masculinespeaks 16 дней назад

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.

For all those who cannot seem to understand the point being made in this video. He first stuck his hand in the caliper, Then waved "no no" So he then used a pencil and 2 sockets to show the force that the piston makes when it comes out, And how it would demolish your hand

@wink2154 15 дней назад

Just use the brake fluid pressure to get it almost all the way out. Then you can remove the caliper and pull the piston.

@jaybee6477 18 дней назад

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

@hoonyfan2924 5 дней назад

Maybe don’t use full pressure when doing that instead.

@fedthefup2823 День назад

A hundred ways to do this, and that's not one of them.

@mikeberry304 19 дней назад

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

@brianellison3525 9 дней назад

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.

Use the brake pedal on the car. Before disconnecting.

@brianellison3525 9 дней назад

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.

@kjelljohansson1799 4 дня назад

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😊

@brianellison3525 9 дней назад

You don't need to hard dump 150 pounds into it. You can bleed the pressure on smooth and easy, and the piston will slowly fall out. Use a disk pad to catch it, no harm no foul. Look like a pro, not a newbie running around trying to get the piston that just got a big ding in it out from under the work bench. Have fun all.

~3" dia. Piston= 7.068 square inches. ~90 pounds per square inch shop air (and ill bet its more like 130 psi) 7.068square inches(90psi) = 636.17 pounds of force. Im sure with an imperfect seal on the inlet port the actual number could be less than half of this Idk. Maybe you need a thicker pencil?

Yes, judging by serious calculations, yes. A wooden block will help
