How do you get the caliper piston to go in when you are replacing rear brake pads on a 2000 seville.  is there a procedure for anti-lock brakes??  THANKS MUCH

Answer
You have to turn the piston inward like turning a big bolt.You will need pictures  of the components within the system that is causing you problems of which can't be done on this website which only allows one picture.  I do not have a website so you will have to e-mail: onlineautohelp@msn.com in order to obtain the information.
