I have a 1978 Mercedes 450 SL (model 107 chassis) and the Right rear parking brake assembly disintegrated inside the PBrake hub. It destroyed the backing plate and *everything* inside the hub. I will need to replace the backing plate, and all the components pertaining to the Parking brake. incl. the adjuster, bolts, Pbrake cable, Everything... First, however I need to disasemble it. I have the Rotor off but cannot figure out how to remove the backing plate. Will I have to remove the axle, and if so, then I would appreciate it if someone can give me a procedure to disasemble it and reinstall everything... Your help is greatly appreciated... ps.. I have a mercedes service CD Rom, but the procedures are hard to see and understand...

Thanks,
Paul
