Had new powerstop pads, rotors and powder coated calipers installed on my 2004 ssr.
Prior to install brakes were hard as a rock. After, they were spongy, no air in lines, so replaced the power booster and the control module, still spongy. GM tech help said to replace booster, then module.
If i clamp both front rubber parts of brake lines pedal is hard as a rock. Unclamp either one and it is spongy again.
GM tech help can't figure it out, what do you guys think?
Any help would be greatly appreciated.
