ML63 AMG Rear wheel whining/grinding noise
Just had all rotors and pads changed in two weeks ago. Started to hear metal-metal grinding noise at low speed (<20km/h) and applying brake at low speed made the noise worse. No vibration, no unusual feeling on steel wheel.
At high speed (>40 km/h), no noise (with/without braking)
Anyone experienced or heart about this problem?
Thanks
