E 350 Van V8-7.3L DSL Turbo VIN F (1995)
Brake Fluid: Testing and Inspection
Hydraulic brake fluid color must conform with the requirements of Federal Motor Vehicle Safety Standard 116. Under this standard, brake fluids are
visually different from other automotive fluids such as transmission, power steering and engine oil.
The color of the brake fluid in a normal brake system in Service can vary from its original color for many reasons. Sometimes a brake master cylinder
(2140) may show significantly different shades of color of brake fluid in the brake master cylinder reservoir (2K478). Some of the reasons for the
apparent difference in color in a system are listed below.
^ Brake fluid discoloration can occur due to heat and/or aging.
^ Brake fluid discoloration can exist when different brands/shades of brake fluid are used in topping off during normal Service.
^ Brake fluid discoloration can occur through the dissolving of color dye used on brake master cylinder internal springs in manufacturer's assembly
procedure.
NOTE: Brake fluid contaminated with a hydrocarbon/mineral based fluid (power steering or transmission fluid) can be detected by an obvious
swelling of the brake master cylinder filler cap gasket. If the swollen gasket condition is present, all brake system rubber parts must be replaced.
All brake tubes must be thoroughly flushed with Ford High Performance DOT 3 Brake Fluid C6AZ-19542-AA or DOT 3 equivalent fluid meeting
Ford specification ESA-M6C25-A before the vehicle goes back into Service.
