The ins and outs of brake system maintenance require skilled hands, a sharp eye, and a focused mind. This video serves as a guide to performing work on master cylinders, valves, and power assist components. Dissecting the master cylinder in order to look at its hydraulic components, compensating port, vent port, step bore cylinder, and other parts, the video also examines metering valves, combination valves, proportion valves, and their functions, while discussing pedal force, mechanical advantage, hydraulic advantage, vacuum suspended boosters, atmospheric suspended boosters, tandem boosters, single diaphragm boosters, check valves, and more. All four modes of bleeding are covered.
