W220 brake pistons stuck
Hi, I'm new to this forum, but today I tried to change the brake pads and when attempting to push one of the pistons back the other extended and failed to return in. Same thing happened for both sides, car rear end is raised; cap is off brake reservoir; we have used pryers. Note this is the outer piston. Thanks

Welcome to the board!
Use more pressure, but make sure you've got some wood or something soft to not ruin the brake piston.
Also best to ask this question in the W220 forum so others can benefit from the following answers.

+1. A bit of wood and a big screwdriver to lever the wood back, worked fine on the rear of my S430.
