Fill the brake master cylinder with DOT 3 or DOT 4 brake fluid meeting Ford specification ESA-M6C25-A.
See Figures 1 and 2
To check the brake fluid level, visually inspect the translucent master cylinder reservoir. The fluid level should be at the maximum level line of the reservoir. If the level is low, top it off using DOT 3 or DOT 4 brake fluid meeting Ford specification ESA-M6C25-A. It is normal for the brake fluid level to decrease as the brake linings wear. If the level is excessively low, inspect the brake linings for wear and/or the brake system for leaks.
