Was looking for steps to replace rear pads and after reading this I didn't notice anybody saying to release the bleeder screw on the caliper so when pushing the piston back in, the fluid will come out of the bleeder and not back thru the anti-lock brake system. I've heard if you force fluid back thru the system to the master cylinder that you can screw up the anti-lock brakes and they ain't cheap to replace! Just heard.
