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.
Section 06-00: Brake System—Service | 1993 Mustang Workshop Manual |
Brake System Diagnosis charts are provided to assist in a broad diagnosis of the brake system's mechanical and hydraulic concerns. In addition to these charts, there are specific component diagnosis charts that cover the Master Cylinder and Brake Control Valve Assembly.
Always check the fluid level in the master cylinder before performing the test procedures. If the fluid level is more than 12.7mm (1/2 inch) below the MAX fill mark of the master cylinder reservoir, add Heavy-Duty Brake Fluid C6AZ-19542-AA (ESA-M6C25-A) or DOT-3 equivalent.
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.
