So like many others, I have had issues with the parking brakes. I've taken them apart, cleaned them and greased gear and everything and new pins. Everything seemed to be ok, but then out of the blue, the left got stuck again. I took the wheel off, took the motor and gear off and went to turn the caliper back to release the brake. But it is stuck, as in completely stuck. Any ideas how I can get it loose so I can move the car and get it home?
