Yeah, like Nemo said. The parking brake uses brake shoes & a drum. The drum acts as the hub for the disc rotor. If you can take off the rotor, you expose the parking brake shoes.

I could not get my rear left rotor off. Took it to a mechanic. He could not get it off. He took off the caliper & the rotor turns freely.

I am going to take the caliper off of the rotor & wire it up so the brake hose stays connected. I'll then test drive a few miles to see if the brake area heats up. If it does then I know the caliper is not the problem. If it doesn't heat up then I know the parking brake assembly is not the problem.

Sound legit?
