Initial Inspection and Diagnostic Overview

Always check the fluid level in the brake master cylinder before performing the test procedures.

Fill brake master cylinder with specified brake fluid to MAX line to 4.0 mm (0.16 inch) below on reservoir. Use High Performance DOT-3 Motor Vehicle Brake Fluid C6AZ-19542-AB or DOT-3 equivalent meeting Ford specification ESA-M6C25-A.

CAUTION: Use of any other than the approved DOT-3 brake fluid will cause permanent damage to brake components and will render the brakes inoperative.

If a brake is locked and the vehicle must be moved, open a bleeder screw to let out enough fluid to relieve the pressure. This bleeding operation will release the brakes but will not correct the cause of trouble.

NOTE: Prior to performing any diagnosis, make sure the brake system warning indicator is functional.

Visually examine front and rear tires and wheel assemblies for damage such as uneven wear patterns tread worn out or sidewall damage. Make sure the tires are of the same size, type and, where possible, same manufacturer. Any tire or wheel that is damaged or excessively worn should be replaced.

Wheels and tires must be cleared of any foreign matter, and tire pressure adjusted to the correct specification.

If tires exhibit uneven wear or feathering, the cause must be corrected. Check steering and suspension components for damage or wear and, if necessary check and adjust front alignment.
