Does a 1982 300SD use a 10 mm Allen Screw to secure the rotors, or is this present in the '85+SDL only.

Visited my rotors a few weekends ago and could not get them off.

Emergency brakes function fine, and hold at 3 clicks.

Just put on new brake pads, and brake hose.

However, I could not get my rotor's off. The fitting that I saw, may have been an allen screw seemed to be devoid of any flat surfaces that might allow an allen wrench any purchase?

I backed away from the task until I had more information.

Advice please!
