Caliper Piston won't come out all the way...

boyerizm · 05-27-2023, 01:52 PM

I’ve been using a tire inflator / wood / old brake pads and have gotten 3/4 pistons out, one is being stubborn. Now that the other ones are loosened up they come flying out while this fourth one begrudgingly comes out a little bit. Are there any other tricks? I’m seriously about to cave and just buy the bbk.

Put the others back in, lock them in position with C-clamps or whatever, then use the inflator. All of its pressure will be directed to that one piston.
