its not designed to push back like the front calipers. the e-brake mechanism is built into the caliper; therefore you must fit a tool into the piston notches and rotate it to move it back. If it doesn't rotate by hand; its seized and replacement is required.

So question is, how am I supposed to take that cable off my caliper for my parking brake?

Are you trying to take it off to replace the caliper? I know the pregen grand prix's parking brake was internal to the caliper. There was a little pin at the end of the cable, and you had to activate the parking brake at the caliper with your hand, and wiggle the pin out. Or just remove the caliper first and try it with it off. I'm not sure if the 04+ style is that way or not. I've never done brakes on one of them.

yes, thats what im doing. taking the caliper off to replace it with the new one.

What I said should work. If not I'll look it up on chilton if you really need it, or maybe search it on youtube if you guys can't figure it out.

Now that I know for sure what parking brake system you have, as far as I've ever seem what primem said is true.

just checked the 05 build options; there were 2 different e-brake caliper options. jl9, j65 had the ebrake as part of the calilper and the z7u had the ebrake in the rotor hat.

getting the cable out the service manual way is a big time waster because the equalizer nut and cable connector clips will be seized. I'm with 02navyblue; remove the cable lever at the caliper and wiggle the cable out. bend the crap out of the old lever arm if needed as it won't be re-used anyway. install the cable on the new caliper before installing the caliper to the caliper bracket. This will give you the slack in the cable needed to get it on the lever arm.

So I believe I now have another caliper seized on my car. I believe its my left one because I just had my rear right done. Anyone know why this is happening. Is it just because its the 2nd year for that body style?
