I just spent most of last Sunday replacing the brake pads on all four wheels of my 2001 Pontiac Grand Prix. I also bled the brake lines since the brakes were exhibiting a lot of "fade" during heavy stops.
These were fairly simple procedures if you have some automotive knowledge. I probably saved at least a few hundred dollars by doing the work myself.
The brake pads were $47 for the front two wheels and $31 for the rear wheels. The brake fluid, brake cleaner and anti-squeal gel added another $20 to the total cost.
Any General Motors vehicle from Pontiac, Chevrolet, Cadillac, Oldsmobile, Saturn or Buick should have very similar braking components. The bolt sizes or bleeder valve locations may vary.
Here are the guides below.
