I just changed my rotors and pads all the way around. The front pistons compress (used a C-clamp). The rear pistons screw clockwise back into the caliper. Good luck, I hope this helped. Rob in Idaho
Hey Nina==Take off the wheel then remove the 2 bolts holding the caliper on. Then pry on the caliper to compress the piston and remove the caliper. Hang the caliper with a coat hanger or wire and don't let it hang by the hose. Goodluck Joe
To replace the rear brakes on a 2007 Buick Lucerne, first, lift the rear of the vehicle and secure it on jack stands. Remove the wheel and tire, then locate the brake caliper and remove the caliper bolts to detach the caliper from the rotor. Carefully slide off the old brake pads and replace them with new ones, ensuring to compress the caliper piston back into the caliper housing. Reattach the caliper, replace the wheel, and lower the vehicle before testing the brakes.
Chevy came up with the brilliant idea of turn in calipers a number of years back. Check the inside of the caliper piston cup. If you see a square depression in the center, it is a turn or twist in caliper. DO NOT try to compress it. You'll damage the caliper and increase your brake job costs. Chances are when a brake caliper wont compress it is the type that must be turned and compressed at the same time and requires a special tool that you can borrow from a local chain auto parts like Auto Zone. That was the case on my 96 Buick Riveria rear disk brakes.
center the piston cup with a Clamp and turn back slow until the cup set back in place
Buick Riviera was created in 1963.
2 the right butt on some of them U have 2 compress the piston AS U are turning IT 2 the right & also the bleeder screw should b open AS not 2 compress old brake fliud backwards into the Master Cylinder.
buick riviera '92. My dad had one and he loved it.
there is no special tool to remove them but one is needed to compress them to get them back on for the rear.
