1992 Ford Mustang Brake Service (ONLINE REPAIR MANUALS)

Pressure bleeding is recommended for all hydraulic disc brake systems.

The disc brake hydraulic system can be bled manually or with pressure bleeding equipment. The brake pedal will require more pumping and frequent checking of fluid level in master cylinder during bleeding operation.

Do not use brake fluid drained from the hydraulic system when bleeding the brakes. Be sure the disc brake pistons are returned to their normal positions and the shoe and lining assemblies are properly seated. Before driving the vehicle, check brake operation to be sure a firm pedal has been obtain...

Disc brake service is extremely critical due to 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 necessary to prevent brake roughness. In addition, the surface finish must be non-directional and maintained at a micro-inch finish. This is necessary to avoid pulls and erratic performance and promote long lining life and equal lining wear of both the left and right brakes.

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

Never use copper tubing as a replacement for steel tubing. Copper tubing is subject to fatigue cracking and corrosion which could result in brake system failure.

Steel tubing is used to conduct hydraulic pressure to the brakes. All fittings, tubing and hose should be inspected for rusted, damaged or defective flared seats. The tubing is equipped with a double flare/inverted seat or I.S.O. flare to insure more positive seating in the fitting. To repair or reflare tubing, proceed as follows:

DOUBLE FLARE/INVERTED SEAT

• Cut off the damaged seat or damaged tubing.
• Ream out any burrs or ...

FUEL SYSTEM PRESSURE RELIEF

Fuel supply tubes will remain pressurized for long periods of time after engine shutdown. This pressure must be relieved before performing fuel system service. A valve is provided on the fuel injection supply manifold for this purpose.

• Remove air cleaner assembly.
• Connect EFI and CFI fuel pressure gauge tool No. T80L-9974-B, or equivalent, to fuel pressure relief valve cap on fuel injection supply manifold.
• Open manual valve on gauge tool to relieve fuel system pressure.

Parking Brake Linings, Replace

The parking brake system is a drum type design mounted in the hubs of the rear brake rotors.

• Raise and support vehicle, then remove wheel and tire assembly.
• Remove caliper as previously outlined, then the rotor assembly.
• Drain differential fluid from axle by removing cover.
• Remove lock bolt from differential pinion shaft, then the pinion shaft from differential.
• Push axle shaft inward to gain access to axle shaft C-lock, then remove C-lock.
• Remove ABS speed sensor, then the axle shaft from axle housing.
• Disconn...

FRONT & REAR SPLIT SYSTEMS

When the brake pedal is depressed, both the primary (front brake) and the secondary (rear brake) master cylinder pistons are moved simultaneously to exert hydraulic fluid pressure on their respective independent hydraulic systems. The fluid displacement of the master cylinder is proportioned to fulfill the requirements of each of the two independent hydraulic brake systems, Fig. .

If a failure of a rear (secondary) brake system should occur, initial brake pedal movement causes the unrestricted secondary piston to bottom in the master cylinder bore. Primary p...
