I need to replace the rear brake pads on my 1985 300D. While I dive into this job I want to inspect and likely replace the front pads at the same time. I have changed many shoes and pads on cars and truck (mostly GM products), but never on one of these or any other Mercedes. I have been searching posts, but I am having a hard time finding everything that I have in question; so here is my list. Thank you in advance for your assistance.

1. Are there brake wear sensors at each wheel? I want to know how many of these I may need to purchase. I brake wear indicator light is not on, but the left rear outside pad is worn way down and the inside pad has not worn much. The right rear pads are worn much more evenly. I believe that I should probably purge all of the old brake fluid.

2. Is there a detailed post for replacing the front brake pads? If not is there anything specific to this car I should about replacing the front pads? I know that the rear pads have a retaining pin. Do the front pads have a retaining pin and if so how is it to be removed? While replacing the pads should I repack the front bearings and if so how do I go about that job? Is there recommended grease?

3. Is there a detailed post for replacing the rear brake pads? If not is there anything specific to this car I should about replacing the rear pads? How do I remove the pad retaining pin? The pins on the rear wheel I pulled look rather corroded and will likely be a real joy to remove. I s the pin held in by friction or is there another part holding it that I should replace as well?

Again, thank you for assistance.

Look for the DIY button at the top of the page. There is a write-up on changing brake pads on the 124 chassis. The procedure on your 123 car is almost the same. You need 4 wear sensors for the front pads. There are no sensors on the rear pads.
