Check the brake fluid at least once a year. You can do this by looking at the fluid level in the plastic reservoir on the master cylinder. The fluid level should be at or near the MAX mark. RWARNING Brake fluid is toxic. If brake fluid contacts eyes, flush eyes with running water for 15 minutes. Get medical attention if irritation persists. If taken internally, drink water and induce vomiting. Get medical attention immediately. If the fluid is low, carefully clean and remove the filler cap from the reservoir. Fill the reservoir to the MAX line with Ford High Performance DOT 3 Brake Fluid C6AZ-19542-AA or DOT 3 equivalent fluid meeting Ford specification ESA-M6C25-A. NOTE: If brake fluid is spilled on painted surfaces, it must be flushed and wiped away immediately. Brake fluid may dissolve the paint finish on your vehicle. RWARNING If you use a brake fluid that is not DOT 3, you will cause permanent damage to your brakes. Do not fill the reservoir above the MAX line. If you find that the fluid level is excessively low - below the seam or ridge on the outside of the plastic reservoir - have the brake system inspected. 350
