Replacing brake fluid (Scorpio 2)

Special tool required: Ring wrench for air bleed valve.

Replacement materials: Brake fluid specification SUPER DOT 4 or FORD ESD-M6C57A.

Brake fluid is able to absorb moisture from the air through the pores in the brake hoses and the ventilation hole in the expansion tank cap. Therefore, during vehicle operation, the boiling point of the brake fluid decreases. Under heavy load on the brakes, vapor locks can form in the brake pipes, which greatly disrupts the operation of the brake system. Brake fluid should be replaced every 2 years, regardless of the vehicle mileage, if possible, in the spring. In this case, approximately 400 cm³ of brake fluid should be removed from each brake caliper. If you frequently drive on mountain roads, the brake fluid should be replaced at shorter intervals. A description of the operating procedures is given on p. 117.

Observe safety precautions when handling brake fluid, see p. 117.
