STOP THE CARĢ7 Master Cylinder Reservoirs Master Cylinder Vacuum Line To Front Brakesģ0 Gain power from vacuum in intake manifold standard dual master cylinder gives front and rear brakes separate hydraulic systems.Ģ6 Master Cylinder If a brake fluid leak occurs in one system, the other system will still operate, making it possible to. forward movement of the pistons causes primary cups to cover bypass holes, hydraulic pressure builds up and is transmitted to the wheel cylinders.Ģ5 MASTER CYLINDER pedal retracts, the pistons allow fluid from the reservoir to fill the chamber Special sensors within the master cylinder used to monitor level of fluid in reservoir, and alerts driver if pressure imbalance develops. Hydraulic pressure created and the force of the primary piston spring moves the secondary piston forward. When brake pedal is depressed, push rod moves the primary piston forward in the cylinder.

It’s the primary braking system using a the pedal connected to a hydraulic system causing it to operate. Disc and drum brakes are the most common type of braking systems used. Friction is created between a moving and a non-moving surface at each wheel to generate the heat. Heat energy is created in the brakes by friction. Stop the vehicle by converting the kinetic energy of the vehicle to heat energy. ![]() How it Works Friction develops heat which absorbs kinetic energy of the car ![]() 2 Friction develops heat which absorbs kinetic energy of the car ![]()
