2000 Mercury Mountaineer Change Brakes

you need brake pads and rotors.

Replacement parts for whatever linings are worn out, whatever drums or rotors are worn or ground beyond the published legal limits, a place that will machine those drums or rotors, the proper tools, the knowledge to avoid the many pitfalls that professionals know about that can cause problems, the knowledge to do the things professionals do as part of any brake work to insure a safe and satisfactory job. "Changing brakes" involves replacing a few parts. That is not the same as a brake job any more than replacing a spark plug is a tune-up.

We don't know if you're working on the front or rear, have drum or disc rear brakes, standard or heavy duty, anti-lock brakes, or what prompted you to want to do this job.
