Normal Operation
WARNING: This page is about a different car, the 2007 Lincoln MKX and 2007 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
During moderate to heavy braking, noise from the hydraulic control unit (HCU) and pulsation in the brake pedal can be observed. Pedal pulsation coupled with noise during heavy braking or on loose gravel, bumps, wet or snowy surfaces is acceptable and indicates correct functioning of the anti-lock brake system (ABS). Pedal pulsation alone or steering wheel nibble when the brakes are applied (frequency is proportional to the vehicle speed) indicates a concern with a brake or suspension component.
Possible Causes
- Brake pad(s)
- Brake disc(s)
- Wheel(s) and tire(s)
- Suspension component(s)
