Hi, I am new to this forum, so bear with on this one! I installed new rear brake rotors and pads on my 2007 G6 4 door. While using a large C-clamp to push the piston back in to the caliper, I broke off the large spring on the back side which is part of the e-brake, I believe. The brakes work fine, but I am not sure it will pass inspection and the e-brake may not be working properly. Is there somewhere I can find directions to replace this part and what special tools would I need? Thanks for the help!
