Brake Discs

WARNING: This page is about a different car, the 2006 Mercury Grand Marquis and 2006 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: Using an impact tool without a torque socket will lead to unevenly tightened lug nuts. This causes brake disc on-vehicle lateral runout and brake roughness.

NOTE: It is generally not required to install new brake discs to address noise issues.

Remove the brake disc. Refer to FRONT DISC BRAKE or REAR DISC BRAKE .
Inspect the brake discs and measure the brake disc thickness in a minimum of 4 places around the circumference of the brake disc. Record the measurements.
- Install new brake discs if any thickness measurement is less than the minimum specification. Refer to FRONT DISC BRAKE or REAR DISC BRAKE .
- Install new brake discs if cracked. Refer to FRONT DISC BRAKE or REAR DISC BRAKE .
- Machine the brake discs if the diagnosis has revealed vibration in the steering wheel, seat or pedal while braking. Heavily scored brake discs, similar to that caused by pads worn down to the backing plate, should also be machined. In order to machine, discs must be above the minimum thickness to machine specification. Refer to SPECIFICATIONS . Refer to BRAKE DISC MACHINING .
