Pulsing brakes.........W210

My 98 has had pulsing brakes for a few months now. The pads are in very good shape. Should I:

1. Pull the rotors and have them turned and use the same pads?
2. Replace the rotors and use the same pads?
3. Turn the rotors and replace the bads?
4. Replace the rotors and pads?

May seem like a stupid question but I hate to throw away good usable pads!

1 or 4, depending on how much you want to spend. 4 is the right way, but 1 will probably work and is cheaper.

That is the general consensus. I was thinking of having my rears turned with new pads. I am thinking of just replacing pads AND rotors.

You can have the rotors GROUND, if they're within spec then use them. I have not had rotors turned in 30years, the finish is what you want when ground.

The problem however is probably the rotor casting, if it warped, chances are it'll warp more, it is not a good casting. I never mess with warped rotors I replace them.

Might as well install new pads, AFAIK you can re-use them, but you're already in there and new pads will seat well on a new rotor.

I have the same problem on this car and the truck too. On the truck it has to do with the calipers not being able to slide around on their mounts. The solution was to remove them and grease the rods they're mounted on. I don't know how the M-B calipers are attached but they have to have a way to slide.

It's interesting too because the car's brakes pulse sometimes and sometimes not so it may be related to worn bushings on the front suspension.

It makes little sense to turn rotors on our cars. First of all it is not much cheaper than replacements. Secondly, it is generally not recommended by M-B. If you really want peace of mind, just replace the rotors and pads on the axle you are having the problem with and you will be a happy camper.
