Brake Bleeding: Service and Repair
Flushing
Flushing the brake hydraulic system involves running new brake fluid through the system until the fluid at each bleeder valve comes out clear. This is the
only way to clean contaminated fluid out of the system. The brake hydraulic system should be flushed with clean brake fluid any time new hydraulic
parts are installed. Flushing is also recommended if there is any question of contamination of the grade of fluid in the system or the mineral oil in the
fluid.
