2007 Ford Taurus Brake Service (ONLINE REPAIR MANUALS)

• Attach a rubber drain hose to bleeder screw of clutch master cylinder, then submerge free end of hose in a container partially filled with clean brake fluid.
• Slowly pump clutch pedal to floor several times and hold it.
• With clutch pedal held to floor...

Power brake operation concerns should be handled as if two separate systems exist.

• Inspect for faults in hydraulic system first.
• If hydraulic system is satisfactory, inspect power brake circuit.
• Press brake pedal firmly and then start engine.
• Pedal should fall away slightly and less pressure should be needed to maintain pedal in any position.
• Install of suitable pressure gauge in brake hydraulic system.
• Record pressure with engine off and power unit not operating.
• Maintain pedal height, start engine and record measurement.
• There should be substantial pressure increase in second measurem...

Pressure bleeding is recommended for all hydraulic disc brake systems.

Do not reuse brake fluid drained from the hydraulic system when bleeding the brakes. Ensure disc brake pistons are returned to their normal positions and the shoe and lining assemblies are properly seated.

Do not shake the pressure bleeder tank while air is being added or after it has been pressurized. This will prevent air from the tank getting into the lines. Do not move the tank during the bleeding operation. The tank should be kept at least one third full.

On models equipped with power brakes, exhaust the...

Whenever new brake components are installed in the hydraulic system, it is recommended that the entire hydraulic system be thoroughly flushed with clean brake fluid.

It may sometime become required to flush out the system due to the presence of mineral oil, kerosene, gasoline, etc., which will cause swelling of rubber piston cups and valves and render them inoperative.

Flushing is performed at e...

Master Cylinder

Disassemble

• Clean outside of master cylinder thoroughly. Drain brake fluid from master cylinder into suitable container.
• Remove stop bolt and pressure control valves.
• Pry up and remove reservoir from master cylinder body.
• Remove fluid control valve.
• Depress primary piston and remove snap ring from retaining groove at open end of bore.
• Remove primary and secondary piston assemblies from master cylinder. If secondary piston does not come out, apply air pressure to secondary outlet port to remove.

Inspection

• Wash components in clean brake fluid only. Use an air hose to bl...

Disc brake service is critical because of the close tolerances required in machining the brake disc to ensure proper brake operation.

Maintaining close control of the shape of the rubbing surfaces is required to prevent brake roughness. In addition, the surface finish must be non-directional and maintained at a micro-inch finish. This is required to avoid pulls and erratic performance and promote long lining life and equal lining wear of both the lefthand and righthand brakes.

Do not attempt to refinish the rubbing surfaces unless precision equip...
