Hi guys, so I was going to start work on my 164LS that sat for 4 years while I worked out of town but I immediately ran into a problem. On trying to move it toplace where I can work on the engine utilizing the steps that Alfisto Steve suggested, I found out that the parking brake is frozen. Actually, it is the driver's side rear wheel that is frozen, the passenger side rear wheel is free. Is the parking brake connected to the rear calipers or is it brake shoes on the inside of the brake disc like it is on my Mercedes GL550? Do you guys have any words of wisdom for me on how to fix this? (The parking brake handle releases with no problem).
