1999 Ford Contour Brake Service (ONLINE REPAIR MANUALS)

Complaints about power brake operation should be handled as if two separate systems exist. Inspect for faults in the hydraulic system first. If it is satisfactory, start inspecting the power brake circuit. For a quick inspection of proper power unit operation, press the brake pedal firmly and then start the engine. The pedal should fall away slightly and less pressure should be needed to maintain the pedal in any position.

Another inspection begins with installation of a suitable pressure gauge in the brake hydraulic system. Take a reading with the engine Off and the power unit n...

The anti-lock brake system operates using a control unit and sensors as follows, wheel lock-up is prevented during heavy braking by modulating brake pressure. The system permits the driver to maintain steering control and stop vehicle in the shortest possible distance under most conditions. During the anti-lock brake operation, the driver will sense a pulsation in the brake pedal and hear a clicking sound. The pedal effort and pedal feel during normal braking are similar to that of a conventional power brake system.

The Hydraulic Control Unit (HCU) is an integrated unit and is locate...

Pressure bleeding is recommended for all hydraulic brake systems. Ensure all dirt and contaminants are removed from master cylinder area prior to removing reservoir cap.

To prevent air from the pressure tank getting into the lines, do not shake the tank while air is being added to the tank or after it has been pressurized. Set the tank in the required location, bring the air hose to the tank, and do not move it during the bleeding operation. The tank should be kept at least one-third full.

On vehicles equipped with disc brakes and master cylinders without proportioners or press...

Hydraulic Brake Fluid Color

Hydraulic brake fluid 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.

Fluid color in a normal brake system may vary from its original color for many reasons. A brake master cylinder may show significantly different shades fluid color between the two brake master cylinder reservoirs. Color may also appear to vary between cast steel and die cast aluminum reservoirs. Some reasons for discolorati...

Remove wheels and inspect brake disc, caliper and linings. Inspect wheel bearings and repack if required.

If the caliper is cracked or fluid leakage through the casting is evident, it must be replaced as a unit.

If caliper is removed when installing new components, clean all components in alcohol, then wipe dry using lint-free cloths. Blow out drilled passages and bores with compressed air. Inspect dust boots for punctures or tears, replace as required.

Inspect piston bores in both housings for scoring or pitting. Bores showing light scratches or corrosion can be cleaned with crocus clo...
