I have an '80 300SD. It had the front cal's replaced(?) in 2003. It has a pulsing I am presuming from the front brakes. I thought the rotors were warped. I had those and the pads replaced;it still pulses at any speed above 15MPH. It is worse slowing from high speeds all the way to stop. Do I need to replace the calipers as well?

My car has "support joints" between the lower control arm and a large cast mount on the body. Your body style may too, I'm not sure. This can be a source of problems in the front end. Check for a tie rod looking rod attaching on the lower control arm, under the spring, then follow it back to the other end where it meets the body. Does the rubber boot look worn/cracked? This may be it.
