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?
