Q: grinding noise (not squealing) when brake

asked by on

The issue comes after a front brake service. New pad (semi metallic), resurfaced rotor. The noise comes when brake at low speed (~10mph). as speed goes down, the pitch of noise goes down. It sounds like grinding, but not sharp noise (not metal to metal grind). brakes function good. checked clearance between dust plate and rotor, brake line and ABS line. Could it be the pad is too hard?


My car has 110000 miles.
My car has a manual transmission.

If the issue did not exist prior to the work being done, then the cause of the unusual noise is due to the pads and/or the interaction between the pads and the particular finish that was left on the rotor. You might take a look at the rotors to determine if they were, in fact, turned. A guaranteed solution to the problem is to use only OEM (dealer supplied) brake friction materials and to buy high quality brake rotors (again OEM is preferred or use a recognizable name brand such as AC Delco but there are others). In quite literal terms, once non-OEM parts and materials are installed, and thus in essence an "experiment" is set up, brake noise, and other untoward effects, can be a result. If you would like a Mechanic from YourMechanic to evaluate this for you, please simply request a brake noise diagnostic and a certified mechanic will be dispatched by YourMechanic to evaluate your brakes and address all of your concerns.
