    Brake caliper issues on 98 malibu

    We're working on my buddies (True) brakes and one of the bolts on the caliper bracket is stripped and stuck in. Secondly the piston in the caliper is extended out and wont compress back in.

    Help! lol. Considering buying a whole new caliper and bracket and cutting the old one out.

    Undo the bottom bolt from the caliper and flip it up to move it off the bracket.

    If the 15mm bolt on the bracket is stripped remove the other bolt, put an impact on the stripped one and pry the bracket off whille running the bolt in reverse. It should catch and either run the bolt out or snap the head off allowing you to pull the bracket. A new bracket will be required.

    The piston in the caliper is either siezed or turned sideways. Try moving it in with a large set of channel locks. Work it side to side if it's stiff.

    thanks, forgot to mentiom its the bottom bolt so we can only flip it down.

    (wont the rotor be in the way to pull the bracket around?)

    When the brakes are applied the piston moved forward, and continues to move farther but doesnt go back in. It has some side to side play


    bolt head is suuuper stripped (grade 10.9 steel)

    Ok if the top bolt is out flip it down. You may have to disconnect the flex hose. but once the caliper is down it will slide back on the slider and off the bracket.

    it is the caliper bracket that we cant get off.. the bottom bolt is stripped to hell.. vice grips cant even grip on anymore.. should we cut off the bolt and drill it out? or heat it up and try and turn it out?

    Ya, if you figure the left side $68 (on sale, normally 80ish) plus tax for a new caliper after giving the old one to them plus $23 per new bolt to enter through the knuckle (need 1). Problem here is that the other side has the same problem with a stripped bolt on the bottom and caliper piston not wanting to go back in. (Both sides of the car the inside brake pad was worn down to nothing while the outer on each side still had half life left)

    All I wanted to do was put my new rotors and pads on

    This is why I should have a Jeep, it'd be more fun to wrench on.

    It's common on the N-body. The pads have to be regularly serviced or they will sieze and cause the inboard to wear prematurely.
