1995 Mercury Sable Brake Service (ONLINE REPAIR MANUALS)

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...

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...

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 inspecting 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, inspect brake operation to be sure a firm pedal has been ob...

On 1996 Continental Models Built Prior to 11/1/95, Diagnosis Of ABS Concerns Should Be Done Using The 1995 Continental Diagnostic Information.

Diagnostic Procedure

Ensure the following diagnosis procedures are used in the sequence and step-by-step order indicated. Following the wrong sequence or bypassing steps will only lead to unnecessary replacement of system components and/or incorrect resolution of the problem. The diagnostic procedure consists of five sub-tests: Pre-test Checks, On-Board Self-Tests, Manual Quick Tests, Warning Lamp Symptom Chart and the Diagnostic Tests.

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

Master Cylinder Overhaul

Disassemble

• Clean outside of master cylinder thoroughly. Drain brake fluid from master cylinder.
• Remove stop bolt and pressure control valves, if equipped.
• Using a screwdriver, carefully pry up on reservoir and remove it from master cylinder body.
• Remove fluid control valve, if equipped.
• 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.
