Vehicle Brake Basics

Brakes are mechanical devices used to slow or stop a moving object, or to prevent the movement of a stationary object. This course discusses the hydraulic braking systems typically installed in modern automobiles and light duty trucks. Similar systems can be used on rotating equipment and machinery. Brake pedal design, vacuum-assisted brake boosters, "master" and "slave" cylinders, emergency brakes, anti-lock brake systems, and the importance of regular inspections and maintenance are all covered.

• Define "friction," "force," "hydraulics" and "pressure" • Discuss how "leverage" and the "pedal ratio" increase braking force • Discuss how "brake assist" or "power brakes" increase braking force • Identify and describe disc brakes and drum brakes in vehicle brake systems • List important characteristics for brake fluids • List the brake system components which should be regularly inspected • Describe the functions of emergency brakes, anti-lock brake systems, and wear indicators on brake linings
