2000 Mercedes Benz ML320 rear rotors

With the caliper assembly off an the center retaining torx screw on the rotor off, the rotor should slide right off. Make sure your parking brakes are off as this will make removal impossible. Also I have seen rotors stuck to the vehicle due to excessive wear of the parking brakes which creates an inside lip on the inside drum portion of this rotor. If this is the case you will need to back off the auto adjuster in the drum assembly. You can access the adjusted from the back of the brake assembly. There is usually a small rubber piece about an inch long that can be removed from the back of the assembly. Inside you will see a wheel with points on it. This is your adjuster. Back the adjuster with a screw driver and this will release some of the parking brake pressure enabling you to get the brakes over that inside lip.
