Diagnosis and Testing

BRAKE FLUID CONTAMINATION

Indications of fluid contamination are swollen or deteriorated rubber parts. Swelling indicates the presence of petroleum in the brake fluid.

To test for contamination, put a small amount of drained brake fluid in clear glass jar. If the fluid separates into layers, there is mineral oil or other fluid contamination of the brake fluid.

If the brake fluid is contaminated, drain and thoroughly flush the brake system. Replace all the rubber parts or components containing rubber coming into contact with the brake fluid including: the master cylinder and reservoir; proportioning valves (non-ABS); caliper seals; wheel cylinder seals; ABS hydraulic control unit; and all hydraulic fluid hoses.

Standard Procedure

BRAKE FLUID LEVEL CHECKING

NOTE: Brake fluid level should be checked a minimum of twice a year.

Master cylinder reservoirs are marked, FULL and ADD, indicating the allowable brake fluid level range in the master cylinder fluid reservoir.

CAUTION: Use only Mopar Brake Fluid DOT 3 Motor Vehicle or equivalent from a tightly sealed container. Do not use petroleum-based fluid because seal damage in the brake system will result.

NOTE: Although there is a range, the preferred level is FULL.

1. Remove the cap.

2. Adjust the brake fluid level to the FULL mark listed on the side of the master cylinder fluid reservoir as necessary. Do not overfill the system.

3. Install the cap.

Specifications

BRAKE FLUID

The brake fluid used in this vehicle must conform to DOT 3 specifications and SAE J1703 standards. No other type of brake fluid is recommended or approved for usage in the vehicle brake system. Use only Mopar Brake Fluid DOT 3 Motor Vehicle or equivalent from a tightly sealed container.

CAUTION: Never use reclaimed brake fluid or fluid from a container which has been left open. An open container will absorb moisture from the air and contaminate the fluid.

CAUTION: Never use any type of a petroleum-based fluid in the brake hydraulic system. Use of such type fluids will result in seal damage of the vehicle brake hydraulic system causing a failure of the vehicle brake system.

Petroleum based fluids would be items such as engine oil, transmission fluid, power steering fluid, etc.
