Looked at a couple YouTube videos. Brakes on the Buick look easy. I need to borrow a caliper piston tool for the rears though. I didn't save one off the tool truck when I retired. :wtf::BangHead::BangHead::BangHead:
Get the screw type. Those cube style suck. Screw type is worth the money in frustration alone. A little crank on piston, follwed with a little push with the screw. No brute force necessary.
Mark your piston and index it to the same spot when piston is compressed. There are tabs on the pads that need to go into the notches. After assembling,cycle e-brake lever on caliper to bring pads up to rotors. 1 to 1-1/2 hours.busdy’s son had no clue, cracked one piston and jammed the other sonehow. Then i had to clean up the mess.
