Brake Discs
WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Using an impact tool without a torque socket will lead to unevenly tightened wheel nuts. This causes brake disc on-vehicle lateral runout and brake roughness.
- Inspect the brake discs and measure the brake disc thickness. Record the measurements. Refer to GENERAL SPECIFICATIONS in this service information.
- If the brake disc is cracked or otherwise damaged, install a new brake disc. For additional information, refer to FRONT DISC BRAKE SYSTEM article for front brakes or REAR DISC BRAKE SYSTEM article for rear brakes.
- If the measurement is below the minimum thickness specification, install a new brake disc. For additional information, refer to FRONT DISC BRAKE SYSTEM article for front brakes or REAR DISC BRAKE SYSTEM article for rear brakes.
- If the diagnosis has revealed vibration in the steering wheel, seat or pedal while braking that varies with vehicle speed, machine the brake disc. 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 specification. For additional information, refer to GENERAL SPECIFICATIONS and BRAKE DISC MACHINING in this service information.
