Stuck brake pistons????????????
Every time I check my brakes, the pistons are stuck making tire rotation difficult. I was taught that the pistons must be able to move freely. I have three cars that exhibit these symptoms.
How can I avoid this problem? Must the pistons be removed, cleaned and new seals installed at regular intervals? Where is the best source for a seal kit and new pistons. Are parts stores a god source or should I purchase genuine Datsun-Nissan parts? How much air pressure ,PSI, is needed to blow the pistons from their bores? In the past, I could not remove the pistons and purchased a rebuilt caliper assembly with pistons installed.
Any suggestions as how I may prevent stuck pistons in the future? I dread repairing 12 brake pistons!!!!!!!!!!!!!!!!
