To change Rear Brake Pads on a 1997 Buick Park Avenue. Remove the bottom bolt on the caliper. The top has a non removable pivot pin. Remove the bolt that holds the brake emergency brake to the frame. Remove the 2 bolts in the rear of the axle plate that hold the caliper in place. (they take a #18 metric socket and you may need a breaker bar to loosen them) With the caliper free from the mount, swing the pad holder up on the top pivot pin and remove the old shoes and replace. Turn the caliper piston clockwise and inboard with a caliper disk brake tool (harbour freight about 19 bucks). Flip the shoe holder part of the caliper back in place and put the assembly back over the rotor. Re install the bolts (blue locktite on the caliper mount bolts and tighten slight snug with breaker bar) retighten the bottom caliper bolt (moderately no locktite)
Follow the directions that sbrit56880 explained. This procedure worked fabulously. If you intend on changing the hardware (dust boots and bolts) because the caliper doesn't move freely, make sure you take the old parts with you if you can, if not at least take the bolts so you can match them up. On the rear the top non removable pin can be removed by popping the chrome cover with the rubber nub sticking out. Don't do this unless you have the replacement kit in your hand because you will probably destroy the cover taking it off. Use the lube that comes with the kit. And guess what? I bought mine at Napa Auto Parts and it was made in the USA! The tool to adjust the caliper piston is made by several manufacturers including Lisle (Part number 25000) Not as inexpensive as Harbor Freight though. By the way this procedure also works for the Buick Riviera.
