I have an 84-300D that is new to me by about 2 months. In replacing the rear brake pads, I noticed that the rear rotors had a significant lip on the edge.

I checked my front rotors and they have the same lip on the outer edge. The front pads are fine. Is that normal for MB rotors? I usually work on my Volvos and have never seen this. I would think they needed rotors if they were on my Volvos.

Thanks,

Don

Replace them. Worn out.

there is a thickness spec on rotors.

i would measure them before changing them. some lip is not a problem.

Yea, there's a certain thickness spec, but if there's a real lip and you don't have a measuring caliper, and it bothers you,
change them - they're cheap.

Brakes are maybe the cheapest and yet most important safety feature on the car.
And it makes you feel good!

Thanks for the info. I will probably do the whole shabang in late June (rotors, calipers, pads and hoses).

I will be back for more assistance then, I am sure.

The lip doesn't mean much, takes a few thousand miles to form. You need to measure the rotors thickness. Usualy you get two sets of pads out of a set of front rotors. Rear rotors and pads seem to last 100k-150k miles. Well unless you have traction control and give it a good work out, then much much less.

If you have no records of when they were last done, just replace them and get a base line. Rotors are cheap.
