Si-man Posted December 15, 2010 Report Share Posted December 15, 2010 Hold the opposite piston in, pull brake so the other pops out. Clean off the piston, stick a small drop of chain lube on piston, spread it around then give the brake a pump to lube up the seal. Usually works.

Even better, lube the inside of the slave Pop the hose out, fill it with oil, pump it in and out a few times, empty it out and rebleed with fluid of your choice Quote Link to comment Share on other sites More sharing options...
