Thread: 2005 Grand Prix GTP Rear Brake Issue

I recently discovered my rear brakes are not functioning. I was removing the lug nuts from the rear wheel while on jack stands. I had a friend holding the brakes down for me. The wheel still spun freely. He had to stand on the brakes with all his weight to keep the wheel from spinning while I was removing the lug nuts. Looking at the rotor, there is a nice film of dust with only a few smudges on it. The e-brake is depressing and unlocking normally, but provides no actual braking when pressed. I have not had done any work on the brakes since I purchased the car several years ago (none appeared to be needed). Any suggestions on the possible cause and fixes would be greatly appreciated. I would hate to go and replace the calipers if the issue is somewhere else.

Thanks,
J.

Thats most likely where your issue lies.

You will need to remove it to see if you can move the piston.

You will need to push and turn the piston.

It appears to be just the passenger side. It looks like I will start by bleeding the caliper and go from there.
