Flushing is done at each bleeder valve in a manner similar to the bleeding procedure. The difference is that the bleeder valve is opened 1 1/2 turns and fluid is forced through the pipes, hoses, and bleeder valves until it comes out clear. Refer to Bleeding the Brake Hydraulic System.

After each valve is flushed, check the level of fluid in the master cylinder. Refill the master cylinder if necessary. After the entire flushing procedure, make sure the master cylinder reservoir is filled to the correct level.
