Automotive Service Technicians and Mechanics Brake Performance Test of an Automobile The brake performance test of FMVSS 105 defines the minimum needs for the brake system on any vehicle driven on the road. The technician should know a bit about the performance test, not for the sake of being able to quote government regulations. Parts of the test define the
Hydraulic Brake Systems Hydraulic operation of the brake systems has been the universal design for more than 60 years. The complete components of oil or hydraulic braking system consists of master cylinder; steel lines, rubber hoses, various pressure-control valves, and brake apply devices at each wheel. Master Cylinder The master cylinder is the start of the brake hydraulic system. It
MECHANICAL BRAKES Internal expanding shoe brakes are the generally used braking system in automobiles. In an automobile, the wheel is fitted on a wheel drum. The brake shoes are fitted in contact with inner surface of this drum to apply brakes. The construction of mechanical disk brake is shown in picture. The whole assembly contains of a pair of brake
Mechanical brake system The details of the drum type manually operated mechanical brake system can be seen in the picture In the motor vehicle, the wheel is attached to a drum. The drum encloses the entire brake mechanism and keeps out dust and moisture. The inner side of the drum is open. The backing plate at the open side of
Pneumatic brake system An air operated brake system or pneumatic brake system is employed predominantly in medium and heavy duty trucks, because of the following advantages. 1. The pressure of the precompressed air allows practically any force required for braking to be developed with a very small effort applied by the driver to the brake pedal. 2. The compressed air
Introduction of brake system The brake system is one of the most significant systems of a vehicle. It has the following basic roles. 1. It should slow a moving vehicle. 2. It should bring a vehicle to a stop. 3. It needs to hold a vehicle stationary when stopped. 4. It permits directional control during maximum braking. In a vehicle
