Brake Master Cylinder: Component Tests and General Diagnostics
Brake fluid level in the master cylinder reservoir should be between 4mm (0.16 inch) below the MAX line on the side of the reservoir and the MAX
line. If brake fluid is low, the red BRAKE indicator will illuminate. To add brake fluid, clean and remove cap and pour clean brake fluid into the top of
the reservoir. Fill to specification mentioned above. Use Heavy-Duty Brake Fluid C6AZ-19542-AA (ESA-M6C25-A) or DOT 3 equivalent. If brake
fluid has to be added often, check all hydraulic connections for leaks.
