Rear caliper won't go in for brake pad replacement.

This is way different than my trucks! Usually i use a C clamp and depress the caliper. The chevy malibu.....doesn't like that so much. In fact it won't move at all. This must have something to do with the automatic unlock feature when you depress the brake pedal to unoco the emergency brake. So, now i need to find out how to circumvent this so i can get even my old brakes on! I wound up working the emergency brake lever and now the caliper is out to far for even them to go on. Any thoughts??

    There must be something that is locking the caliper piston in the out position. The emergency brake isn't on, but there is no handle to release it either. You depress the brake and press the emergency brake again and the car diengages it. So, i'm just wondering how to do that without pressing the brakes on my already extended caliper piston.

    Thanks

    Thanks for the post. I did find a post last night about the piston needing to be screwed. I was able to put a wrench on it and screw them back in and insert the brakes. Thanks again.

    What I was meaning was that the piston may have to be screwed back in to the caliper,instead of just pushing it back in. Are there any notches at the face of the piston where a tool would lock in and turn it? I know I hate the new stuff myself.

    I think that maybe unlike the old calipers these may have to be screwed in and it probably takes a special tool?

The pistons have to be screwed back in place,I use a pair of needle nose plyers while applying constant pressure to piston.They can be rotated both left & right but you will notice soon which way pushes them in.

I realize this is from '06, but someone may find it useful. The rear piston has to be turned clockwise while pressing it in. There are specialty tools for this, but needle-nosed pliers do just fine. Once it's in align the notches to align vertically in relation to the caliper. If you apply too much force with a c-clamp it can damage the parking brake mechanism built into the caliper and require replacement.

Struggling to depress pistons on rear brakes. Hoave used G-clamp, Made a special tool with nut and bolt. Still struggling.

The pistons in the caliper should retract without much effort. A "C" clamp is usually all you need to do it. I suspect you have a seized caliper or possibly a kinked or crushed brake line (preventing the brake fluid from returning to the master cylinder when the piston is depressed) feeding that caliper - but isn't very likely.

Hi, Do I need a special tool to depress the caliper piston or can I use a G clamp? I did this on the front brakes but the rear piston seems a lot tighter.

You can use a "C" clamp...but be sure to use the old pad that goes on the piston side of the caliper...place the old pad back on the piston and then use the "C" clamp to depress the piston back into the caliper..this will prevent damage to the piston...also, to aid in this process, you can remove the brake fluid resevoir cap and put a towel around it so it doesn't leak all over the floor

How do i change the brakes on a 2000 pontiac sunfire

Pull the wheels off. Remove the calipers. There are usually two bolts. Remove the pads from the holders. Use a c-clamp to depress the piston. Usually you have to crack the brake bleed valve in order to do this. Replace the pads and the holders to hold them in place. Tighten the bolts that hold the caliper. Replace the wheel and lug nuts.

How do I get the rear brake cylinder depress back in when putting on new brakes.

If it does not push back with a c-clamp,then it will turn to go back in,the right side,and the left side will turn either left,or right hand to go back in,depending on witch side you are working on.

disc brakes on the rear of a vehicle have a screw out mechanism that attaches to the ebrake . this means that you must turn the caliper piston to recess into the cylinder.
