1995 Ford Mustang Brake Service (ONLINE REPAIR MANUALS)

On models with anti-lock brakes, the brake hydraulic system must be depressurized before disconnecting any hydraulic lines or fittings. Depressurize the system by pumping the brake pedal a minimum of 25 times with the ignition in the Off position.

Except Aspire, Capri, Escort, Mustang Cobra, Probe & Tracer

Removal

• Remove brake fluid until reservoir is half full.
• On Continental, Sable and Taurus, if equipped, turn air suspension service switch Off.
• On all models, raise and support front of vehicle, then remove wheel and tire assembly.
• Remove caliper locating pins.
• Lift caliper assembl...

Vacuum Assist Diaphragm Type

The vacuum assist diaphragm assembly multiplies the force exerted on the master cylinder piston in order to increase the hydraulic pressure delivered to the wheel cylinders while decreasing the effort necessary to obtain acceptable stopping performance.

Vacuum assist units get their energy by opposing engine vacuum to atmospheric pressure. A piston, cylinder and flexible diaphragm utilize this energy to provide brake assistance. The diaphragm is balanced with engine vacuum until the brake pedal is depressed, allowing atmospheric pressure to unbalance the u...

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...

Power Booster, Replace

Aspire

Pump brake pedal several times to exhaust any vacuum in the booster.

• Remove master cylinder as described in "Hydraulic Brake Systems."
• Disconnect vacuum hose from power brake unit.
• From under instrument panel, remove brake pedal clevis pin, then detach pushrod from brake pedal.
• Remove power brake unit attaching nuts, then remove power brake unit.
• Reverse procedure to install noting the following:
• Ensure proper clearance between pushrod and master cylinder exists as described under "Adjustments."
• Bleed brakes as described in "Hydraulic Brake Systems."
• Torqu...

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 lefthand and righthand brakes.

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