1 If your brakes can work properly , good brakes are essential for safety during dn、ruvtg.

2. The disk brake is the best brake which is generally due to its simpler design , lighter i .elju Ind better braking performance.

1. The most vital factor in the running and control of the modem vehicles is the breaking system.

2. Brake fluid is a special liquid for use in a hydraulic brake system.

3. The small forces applied to the brake pedal usually produce relatively large forces.

4. The rate of slowing down or retardation is governed by the speed of conversion of energy.

5. Brake is a friction device for converting the power into heat by means of friction

6. To decelerate and stop the moving automobile, the service brake are usually used.

7. The brake lining of a friction maternal are secured to the shoes by brass

8. The brake drum is mounted on the wheel hub.

1 brake : the means of bringing to rest a moving vehicle in a shortest possible distance.       

2 service brake : stop or slow a car by depressing and releasing the brake pedal. 

3 hand brake : keep the car from rolling on unleveled ground.  

4 drum brake : a backing plate , brake shoes , wheel cylinder , return springs etc.    

5 parking brake : hold the automobile at rest.

1. An automobile brake system is actually a friction device to change power into heat（实际上就是一种把动力转变成热量的摩擦装置).

2. Basically , automobile brakes are of two types: the mechanical brakes and the hydraulic brakes (机械制动器和液压制动) 

3. The most vital factor in the running and control of the modem vehicles is the automobile brake system (汽车制动系统).

4. There are two brake shoes at each wheel. The bottoms of the shoes are held apart by an adjuster. The tops of shoes are held apart by a wheel cylinder（蹄片顶部由轮缸分别固定）

5. Brake lines are steel tubing with copper and lead coating to prevent rust and corrosion ( 以防锈蚀)
