Flushing Hydraulic System
1982 Chevrolet Chevette L4-111 1.8L DSLSECTION Flushing Hydraulic System
Fig. 27 Flushing Hydraulic System:
Whenever new brake components are installed in the hydraulic system, it is recommended that the entire hydraulic system be thoroughly flushed with clean brake fluid.
It may sometime become necessary to flush out the system due to the presence of mineral oil, kerosene, gasoline, etc., which will cause swelling of rubber piston cups and valves so they become inoperative. The procedure is as follows:
Flushing is performed at each wheel in the same manner as the bleeding operation except that the bleeder valve is opened 11-2 turns and the fluid is forced through the lines and bleeder valve until it emerges clear in color, Fig. 27. Approximately one quart of clean brake fluid is required to flush the hydraulic system. After completing the flushing operation at all bleeder valves, check to ensure the master cylinder is filled to the proper level.
