Hey guys,
I replaced my front rotors/pads a month ago hoping to reduce the vibration while braking.
This made almost no difference.
I'm guessing the rear rotors are warped
I thought I read on the Gm forums before it disappeared that replacing the rear rotors are a little more involved.
I haven't been in there yet so I don't know what to expect.
Brake lines?
Special tools?
Caliper piston compressed or screwed back in?
Thanks

my rotors up front needed to be cut very badly, when they were, the car was riding so smooth.

The only thing I see harder about changing the back ones is that you cant turn the rear wheels, so space is limited

Rear rotors aren't too bad You will have to hand wrench the caliper bolts and the anchor bolts out because of the limited space. Follow the parking brake cable forward from the caliper to the control arm. There you will see a 13mm bolt take it out it helps you get the caliper high enough to remove the rotor. You may need to screw the piston in a bit cause of the new rotor. I would change the pads also at this time. If you do you will have to screw the caliper piston the whole way in.If you don't have the tool try a pair of needle nose pliers opening them to the slots of the piston and turning them in (to the right).Align the slots up and down to accomidate the pins on the pads.Clean the hub flange a little if its rusted with a wire brush before you put the rotor on.Now install the rotor and hold it on with a couple lug nuts clean and lube the caliper anchor bolt it to the car then install the pads. Now put the caliper on and tighten the bolts.Now to adjust the caliper get a pair of vise-grips and clamp them onto the parking brake arm on the rear of the caliper in the area where the cable connects. Move the arm in the direction the cable would pull it back and forth a few times. You should see the piston and inner pad moving into the rotor. When the arm doesn't move as far you should be there.

Ok thanks again! I did my rear brakes/rotors today and my vibration is gone. woohoo!! Although screwing in the piston was a pain in the neck:P
