Howdo I get the rear rotors off?
1983 300SD. I am trying to get the rear rotor off to replace it. Is there a release screw or spot that I am missing? Do I need a special tool somewhere. Need Help

Hello ,
I am replacing rotors on my car as well. Put on your safty glasses. I use "P B Blaster" a type of penatrating oil. Put a few drops arount the hub. Be aware that your e-brake shoes are behind the hub. If you get them oily use brake cleaner and spray them clean. then get a large hammer ...a sledge hammer works well. You dont need a lot of strength. The weight of the hammer will do. You can also use a 2x4 x12 in. block of wood and a smaller hammer, just give it a real good whack! Its all about energy transfer ......... Give it a square hit right on the face. Between the bolt holes. It will bounce right off. Clean off the hub with some sand paper. |

I almost forgot ..... I believe there is a small bolt holding the rotor in place. You need a 5MM hex. Remove that first.

I do not recall a bolt holding anything in place. Just remove caliper and make sure your e-brake is OFF. Give her a nice whack if needed.

Thank you for your help. Where is the hex bolt? The only bolt I see is the one in the center of the hub. Also by knocking the rotor off with a hammer won't I damage something in the e-brake system. How often does the e-brake system have to be replaced?

Mine has a countersunk screw that holds the rotor in place. It's between 2 of the lug-bolt holes. Once that's out, follow Anthonies instructions. Repeat as needed.

Are the SD systems different from the 300D W123's? Just wondering, as the right rotor on my '83 just almost fell off after the caliper was removed in preparation for changing out the CV shaft. Its possible that the e-brake shoes are adjusted out quite a bit, and that there is a lip on the drum somewhat like outside the main pads after some wear has occurred. Also the hex bolt in the center of the hub holds the CV shaft in place, don't remove that one!
