I have a 2.2 hdi 16v sx, recently changed brake pads thinking this may help, but no. The handbrake lever on the calipers has stuck on both sides. I can pull the handbrake but they wont release, I have to manually knock the levers open with a hammer. So now I don't use handbrake just leave car in gear. I've spayed with lots release oil with no success. Is there anyway I can release levers somehow recondition them, or am I gonna have to replace calipers?😓 Ideas???
