How I removed the pistons from the calipers to change the seals.

Connect it back to brake line either and hit the brake pedal... but have it sitting in a basin.... or oil everywhere... Good video keep it up....

Might want to put something soft to stop the piston when it flies out. I've had composite pistons crack when they hit the fixed side of the caliper, under air pressure.

My friend. Please be careful. Keep your face out of the way. Years ago, I dropped my guard for a moment and the piston hit me right up the nose. The piston really can fly out of there!

Is easiest and safest to pump out the piston by the hydraulcs before you take it off the bike. As soon as th piston is clear the pressure drops to zero, it cannot get launched anywhere, unlike with Air. It might make a mess if you're unprepared.

@Mickleblade. You are so right on how to get the piston out. Your method should be mentioned in all the videos as the best way so people will know to leave their brake hoses connected. Only occasionally other methods have to be used.
@mickleblade Жыл бұрын
@@bottmar1 I think there's a fundamental misunderstanding of hydraulcs. Even the Haynes manual gets it wrong and claims its safer to use air. A well seized caliper will only come out with hydraulc force.

@@mickleblade my 2 cents is if the hydraulics cant move it enough to remove the piston, its probably too faregone and not smart to be connecting it back to the hydraulics relying on them to stop you!
@mickleblade Жыл бұрын
@@Luckingsworth not so. I've had seized pistons that the hydraulcs just pushed out. A good clean and new seals and fluid and they were fine.

Block of wood between piston and caliper to prevent damage to you & the piston.

You should put a piece of wood in the caliper to prevent the piston flyin out and get damaged

I used a long extension and jammed and then cramped in a trailer hitch and started rotating the piston and it came out then I used salt and vinegar to get rid of the rust

I use an old car key to push the boot in And poke the hole hole hole in it my brand new boot and I gave up...... So I put the brake pads in visa Versa And put on an amazon caliber which doesn't drive very much but the pads are angled because I had a sticking guide pin on the old caliber...

Approximately how many PSI did it take to free these caliper pistons?

90psi

$50 for a cheap HF compressor, no excuse not to in my opinion. It won't run air tools but you can do this and inflate tires with it.
@bestguitarchannel2 жыл бұрын
if you are working on anything with tires and an engine or wood or anything more than hanging pictures on the wall you should get a cheap compressor. Harbor Freight, Walmart, Amazon, Ebay. You should get one for sure.

@somedaysoon332 жыл бұрын
Car/truck calipers require more pressure, could try hooking it up to the brake line and pushing it out with the brake pedal. Is it really rusted out? If it's really rusty then the cylinder likely has pitting and I would replace it. Otherwise you could try some penetrating oil on it, and some heat to press it out.

@royluckadoo67052 жыл бұрын
Can be very dangerous ! Should mention that anyone doing this should avoid putting fingers near the caliper. Best to put in a vice if using compressed air and put a piece of wood outside of the piston to avoid piston flying out aggressively.

The piston is just going to pop out... now you don't want your hand under the piston. In this video I just held it with a rag and pointed the piston down into the toolbox table to catch it. Common sense should tell you not to hold it in the palm of your hand with the piston facing into it.
