I was doing the brakes today, all the pads were at about 50% so it was just suppose to be a clean and grease job. the last one was down to almost no pad, the caliper piston boot was damaged and i assume the corrosion had got into the seal and it wasnt releasing as it should. i picked up a new caliper but i cant get the parking brake cable out of the caliper. i have soaked it with penetrating fluid and will leave it overnight and see if that helps. I'm all ears if anybody has any suggestions.
