Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hi Im david. do the caliper pistons retract ok when using a c clamp or appropriate piston tool?
ok. do you have new pads on hand? to put in and have someone apply the brakes while you watch for even and smooth piston operation?
also, how clean or dirty is the brake fluid?
you have someone apply the brake and you watch for proper operation of the caliper. its often difficult to troubleshoot a problem without being at the vehicle. sorry you feel that way. apparently you have a bad caliper problem or contaminated fluid, but i dont throw parts at vehicles til something fixes it. anyone can do that. good luck and good day.
The right rear caliper isn't sliding, so clean and grease the slides.
The left rear caliper appears not to be working at all, replace it, clean and grease those slides as well, bleed the brakes.
