The rear brake caliper piston wont slide back into position as like the front brake caliper pistons, due to the parking brake actuator operates from the same piston. You have to apply pressure and at the same time screw the piston in the clockwise direction. You have four slots on the caliper piston, make sure one of those slots line up with the peg on the inner brake pad, seen many cases where the pad gets worn on the outer surface (uneven)from improper pad installation which in turn can create all kinds of problems.<uneven braking - premature pad wear - vibration - noises etc....>You can buy one of those tools at most parts stores, or just get a pair of needlenose pliers and screw it in with two of the slots in the caliper.Just curious, what is the mileage on the 2002?

Thanks a lot !In the main time I figured it out , but good to know I did the right thing!Abou 14000 miles , my friends car and she was very upset about the extremly short life of the pads. The dealership said it's normal , I don't think so! Any idea why they have worn so fast ?Thanks again !:D Lajos

14K? Sounds about right... How long did she expect?

Hopefully you didn't replace with "long-life" or "dust-free" pads...

From dealership experience, you can't really put a mileage stamp on how long pads will last. Give you an example, one of my Q-45 customers is a traveling salesman. We just performed the 60k maintenance on his vehicle and have yet to replace the brake pads on the front or the rear. Why? Because he travels throughout the southeastern states and most of the mileage is interstate driven, so in turn the brakes are used at the minimum level. On the other side of that scenario, we have a customer with a G-20 and runs a paper route delivering the newspaper, he might get 7,500 miles (if he's lucky)from his front pads. I have seen a few of the I's come in with premature rear brake pad wear, first thing I would check is be sure the rear parking brake cables aren't sticking or binding, second thing to think about, did they might by chance happen to drive away one day with the parking brake applied? Two things we always do when performing a (pad) brake repair. We soak the factory pads in BG brake quiet which will 99% of the time eliminate the possible of brake noise, second thing we apply the (gold in color) PBC grease to the back side of the pad and to the areas the pad slides between the hardware. The grease has a very high in lead content, which has proven to help cushion things between the pads. shims, and caliper. Method has worked well for us for many years in helping minimize brake repair comebacks!

Most brake noise is caused by vibrations that occur when pressure is applied. BG Stop Squeal works on the simple principle of impregnating the brake pad with ingredients that reduce sticking between the pad and rotor. When pressure is applied, the vibrations are significantly reduced, thus brake noise is stopped or is markedly less noticeable. http://www.bgprod.com/products.html
