You will have to remove the cap from the Master cylinder.This will release the pressure on the braking system and should allow you to easily compress the caliper piston. * * * * * Be sure to wrap a cloth around the master cylinder, because when you do this brake fluid gets all over everything and it's a very good solvent--it especially likes to dissolve paint. And then use a big C-clamp to compress the piston. Even with the pressure released it still takes some work to compress caliper pistons.
Yes, there is such a thing as twin-piston calipers.
A piston seal is a gasket designed to keep fluid from leaking around the piston. Piston seals are commonly used in brake calipers.
if its your rear calliper its because of the handbrake adjustment mechanism, remove the capping screw and then wind the Allen head adjustment bolt right out, if that's not the case you may have wedged it on the angle when compressing the piston, good luck
the piston on the rear calipers will turn in a clockwise motion and that is how they retract.
use a c-clap
you want to collapse it flush with the caliper, dont pust it in to where the piston sinks, just flush will do ya'
When there is to much resistance to retract the piston, When the rubber piston(s) boot/seal is damaged/torn, When the bleeder is broken/stripped,
Poor lubrication. Excessive rpm's. Defective piston. Problem with the wrist pin, bushing or piston rod.
You will need the tool to retract the calipers. The piston in the rear calipers have to be turned clockwise as you compress them back in.
try manciniracing.com and see if they carry them.
No. If your calipers are leaking, they need to be replaced. Calipers leak because they're worn out, or because you didn't change the fluid and it corroded the inside of the piston bore.
with a large pear of channel locks,or a caliper compressor
