Arrow Question about changing rear brakes

I have an '04 RL and last night I was able to change my front brakes just fine. On the rear brakes, I am having trouble compressing the calliper to fit it back over the pads. Seems like the emergency brake is adding pressure or something and not allowing me to compress the calliper. Any ideas how to relieve that pressure so the calliper can be compressed? Do I have to bleed the lines?

Thanks for any help you can provide. I always appreciate the help from those with experience on my problems. This is the first car I have had that have wanted to do most of the work on myself.

are you twisting the calliper? the rear brakes need to be pressed and twisted to compress, more like screwing it in than compressing it...

there are two vee shaped slots in the rear caliper piston face. you have to screw the caliper piston back into the caliper by locking a service tool into these pins and rotating clockwise to bottom the caliper piston before installing new pads. If you don't have the tool try with a couple of helpers to hold the caliper, and hold the screw drivers putting two flat head screw drivers in vertically to the slots and then a third screw driver in between the two screwdrivers, to rotate the piston. Once installed, ratchet the handbrake lever a few times to wind out the caliper piston to get good hand brake actuation. good luck

or when I did it, a pair of needlenose pliers worked well. It should only be a handful of turns before its bottomed out

2004 BLUE Ion Redline

All you need in life is two things: WD-40 and duct tape. If it doesn't move and it should, use WD-40. If it moves and it shouldn't, use duct tape.

Installed: K&N CAI, B&M shifter, IRotor cross drill rotors, Hawk pads, Vector 940 (soon hardwired)
Next up: CTI over axle bend with magnaflow

Yes! The caliper tool works great, see if you can rent one from the auto parts store. The 1st time I did mine, I was able to get the pads in without it, but the 2nd time, the caliper wouldn't compress, even when I spun the piston. It needed to be spun and squeezed at the same time, which is exactly what that tool does.

I swear the threads on the pistons must be invisible or something.....


Seriously folks, GM started doing this on rear brakes 20 years ago.

Ok, so, like, yeah, umm....
