I had same problem, 1st see if you can pry open the piston just a little bit by
shoving a flat screw driver between rotor & brake pad. And or in my case I
had to grind off the edge of the rotor as tall as the pad in order to slide out the
pads.Then replace the unit..
Usually you can put a screwdriver between the edge of the rotor and the caliper and pry up on it. Stuck from rust, heat, or piston in caliper will not release? Rust, heat, it will pry up. Not releasing, open bleeder screw if possible without breaking it off.
Look at the pistons in the caliper. If it is a cup type piston there could be several reasons for this, (requiring researching technical manuals). But if it is a solid piston with what appears to be 4 raised tabs around the piston in a + configuration this suggests that you may need to screw the piston back into the caliper turning it clockwise. Sometimes this takes quite a bit of turning. Otherwise the pistons are stuck, or you might need to open the bleed screws and compress the pistons as some vehicles have one-way pressure valves in the system. . To add a '96 cutlass caliper piston has to be screwed in clockwise with also applying steady pressure
Sticky/stuck caliper slides, sticky/stuck caliper piston, collapsed brake hose, pinched brake line,
i have 1991cutlass supreme v6 my digtial gas gage stuck
A stuck caliper piston. Stuck caliper slide pins. Pinched brake line/hose. Frozen/stuck parking brake cable/mechanism.
what i would do is get some wd40 a pry bar and pry tht sucker right off.(you may need a new rotor after that or at least resurface yours)
Perhaps throttle plate is stuck and needs to be freed -try a screwdriver to do so
Throttle plate stuck in open position
The caliper on your car may not be retracting properly due to a few reasons, such as a stuck piston, worn out seals, or air in the brake lines. It is important to have a professional inspect and repair the caliper to ensure safe braking performance.
Check to see if the throttle plate is stuck
The brake caliper may not be retracting properly due to issues such as a stuck piston, worn out seals, or debris blocking the movement. These issues can prevent the caliper from releasing pressure on the brake pads, causing them to drag against the rotor.
that's not how you relese pressure on the caliper. you disconnect the brake fluid hose from the caliper and that will relese the pressure. if the caliper still won't move then you need to take the caliper apart and clean it good because the piston is most likely getting stuck.
