Speaking of brakes, I replaced the front brake pads on my newly acquired 1987 300TD. It was so easy. I have done the rear brakes before on a 124 but not front. Compared to the rear, the front is a lot easier. No pins to punch out.

When I replaced the rear brakes, I could use a long screw driver to force the piston back. I tried that on the front, no luck. It was very tight (I did have the fluid reservoir cap off). So I took out my C-clamp. Here is a tip iif you use a C-clamp to force the piston back. Use a replaced rear brake pad in between the C-clamp and the caliper piston. Work wonders and won't damage the piston.
