'97 Mercury Sable, Grinding New Brakes
I have a 97 Mercury
Sable and I did a brake job, replaced back rotors w/pads. Now whenever
I am braking there is a "grinding" noise like worn out brakes
on the rotor. With the wheels off nothing was found, no scratches, scrapes---what
could it be?
It just may be the brake pad material. There are different grades of brake
pad material and in most cause one would think that the better the grade
the better the brake. But there is a trade off in some cases. Using a
too aggressive semi-metallic brake pad on the rear of a vehicle of your
type can result in a noise. Not a squeak or a squeal but a grinding type
noise. The fix is installing the brake pads from Ford/Mercury or an aftermarket
that is low in metal content. But never install a brake pad that is not
recommended by the manufacturer for the vehicle! Getting the right friction/braking
material on the rear of your Mercury should quiet things down.
