Hydraulic System: Service and Repair

Notice: Do not use alcohol for flushing the system or cleaning assemblies where alcohol could be trapped and contaminate the brake fluid. The contaminated fluid can then cause the failure of the rubber components in the system.

Flush the entire hydraulic system be thoroughly with clean brake fluid. Flush if there is any doubt as to the grade of fluid in the system or if fluid has been used and contains the slightest trace of mineral oil. Flushing is performed the same way bleeding is done, except the fluid is forced through the system until it runs clear in color at all bleed valves. Approximately one quart of fluid is required to flush the hydraulic system. Replace all rubber parts that have been subjected to contaminated fluid. After Flushing the system check the fluid level at the master cylinder. Refer to Master Cylinder Reservoir Filling.
