Abstract
In the vehicle braking system has a very important role, failure will result in disaster if serious consequences. The main parts of the braking system is the brake, in the modern car is still widely used in high performance brake shoe - brake drum. The design of the friction drum brakes were related to the design and calculation., the first model of the vehicle according to the given parameter and the technical requirements, determine the brake structure and, brake main parameters, and then calculate the braking torque brake, brake shoes on the pressure distribution, deformation shoe, brake effectiveness factor, braking deceleration, wear characteristics, brake temperature, etc., and in this brake on the basis of the structural design of major components. Finally, assembly drawings and parts to complete mapping.Key word： Light truck，drum brake, braking torque, brake efficiency factor, braking deceleration.
