Hydraulic pressure is required to operate this braking system. Force is applied to the brake drum through the master cylinder. The master cylinder develops the required pressure to operate the system. Single master cylinders are used in racing cars. Due to the regulation of the duel circuit brakes, the tandem master cylinder is incorporated in single housing with two master cylinders connected in series. It controls the pressure variation in both the circuits. The reservoir in this system maintains the level of oil in the cylinder which may be disturbed due to temperature or limited leakages. Master cylinders are of two types Lockheed master cylinder and girling-type cylinder (Figure 9.9).
Hydraulic brake systems

For motor cars this unit is usually mounted on the engine side of the body bulkhead structure, through which a push-rod connection is made to a down-hanging or pendant brake pedal that is spring returned to the off or brakes released position. In some light commercial vehicle applications (and earlier car practice) the master cylinder is mounted on the chassis frame where it similarly connects via a push-rod to an up-standing brake pedal. The master cylinder acts as a hydraulic pressure transmitter, because it contains a sealed piston that slides within a cylindrical bore whenever the brake pedal is depressed.

Operation of the brake pedal forces fluid from the master cylinder under considerable pressure to the wheel cylinders or disc brake calipers. In turn, the wheel cylinders act through connecting links to force the brake shoes out against the surfaces of the brake drums, or to force brake pads against the sides of the brake rotor (disc). A mechanical linkage to the rear wheel brakes is usually provided to serve as a parking brake, although some current production vehicles use a hydraulic interlock to actuate the parking brake system.

The hydraulic disk brake consists of an actuation lever coupled to a master cylinder, mounted on the bicycle handlebars, a brake caliper (mounted on the bicycle fork, when the front brake is applied), brake pads (friction material), master cylinder, conduit or hose, hydraulic fluid, and rotor. Braking starts when the brake levers are pressed and push the master cylinder that is inside the body where the lever is attached. The movement of the master cylinder presses the fluid generating high hydraulic pressure that is transferred through the conduit to the caliper; in this, the pressurized fluid moves the piston inside, which in turn moves the brake pads connected to its structure, pressing them against the brake rotor. After the pads contact the rotor, greater forces can be applied to the brake lever, consequently increasing the pads clamping force on the rotor. See Fig. 1.

With conventional service brakes, the braking sequence is initiated by force applied to the brake pedal. The force that is applied to the brake pedal is then converted into hydraulic pressure via the vehicle’s master cylinder. Brake fluid is the transmission medium, between the master cylinder and the brakes. In order to amplify the actuation pressure, a brake servo unit gives higher hydraulic pressure to the brakes. This makes braking easier and is used in power-assisted braking systems.
