Inspection and Verification (Start Testing Here)

Visually inspect the following components for mechanical or electrical problems:
Mechanical
- Brake master cylinder
- Brake caliper piston
- Disc brake rotors
- Wheel bearings
- Brake pads
- Power brake booster
- Brake pedal linkage
- Booster vacuum hose
- Tires
- Debris
Electrical
- Parking brake switch
- Damaged or corroded wiring harness
- Brake master cylinder fluid level switch

For low or spongy brake pedal concerns:
- Check and, if necessary, refill the brake master cylinder reservoir.
- Bleed the brake system and retest the brake pedal feel.
- If the brake pedal is still low or feels spongy, check the wheel bearings.

For slow or incomplete brake pedal return concern:
- Inspect for binding, damage, correct installation or interference at the brake pedal.
- Check the power brake booster for binding, damage and correct installation.

For a vibration concern when the brakes are applied:
- Road test the vehicle
- Apply the parking brake and note if vibration is felt.
- If vibration can be felt while applying only the parking brake, use a hub-mount brake lathe to machine the rear disc brake rotors if final thickness will be within specification. Retest the vehicle for normal operation.
- If vibration is only felt while applying the brake pedal, use a hub-mount brake lathe to machine the front disc brake rotors if the final thickness will be within specification. Ford recommends on-vehicle rotor machining. Follow the lathe manufacturer's instructions. Retest the vehicle for normal operation.
