BRAKE FLUID CONTAMINATION
Indications of fluid contamination are swollen or deteriorated rubber parts.
Swollen rubber parts indicate 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 fluid separates into layers, there is mineral oil or other fluid contamination of the brake fluid.
If brake fluid is contaminated, drain and thoroughly flush system. Replace master cylinder, proportioning valve, caliper seals, wheel cylinder seals, Antilock Brakes hydraulic unit and all hydraulic fluid hoses.
Scheme 44
Always clean the master cylinder reservoir (1) and cap (2) before checking fluid level. If not cleaned, dirt could enter the fluid.
The fluid fill level is indicated on the side of the master cylinder reservoir (1).
The correct fluid level is to the MAX indicator on the side of the reservoir. If necessary, add fluid to the proper level.
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 or an equivalent from a tightly sealed container.
| CAUTION | Never use reclaimed brake fluid or fluid from an container which has been left open. An open container of brake fluid 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. |
Scheme 45
- Install the prop rod on the brake pedal to keep pressure on the brake system.
- Remove the reservoir cap and siphon fluid into a drain container.
- Disconnect the electrical connector from the fluid level switch in the reservoir (2).
- Remove the reservoir mounting pin.
- Remove the reservoir (2) from the master cylinder.
- Remove old seals from the cylinder body.
