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...

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...

Remove wheels and inspect brake disc, caliper and linings. The wheel bearings should be inspected at this time and repacked if necessary. Do not get any grease on the linings.

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

Should it become necessary to remove the caliper when installing new parts, clean all parts in alcohol, then wipe dry using lint-free cloths. Using an air hose, blow out drilled passages and bores. Inspect dust boots for punctures or tears. If punctures or tears are evident, install new boots during assembly.

Single Piston Calipers

The caliper assembly consists of a pin sliding caliper housing, inner and outer shoe and lining assemblies and a single piston, Figs. through . The caliper slides on two pins which also act as attaching bolts between caliper and the combination anchor plate and spindle. The outer brake shoe and lining assembly is longer than the inner brake shoe and lining assembly. Inner and outer shoe and lining assemblies are attached to the caliper by spring clips riveted to the shoe surfaces. The inner shoe is attached to the caliper by installing the spring clip to the i...
