Braking System MCQs

The brake bleeding process removes . . . . . . . . from system.

The mechanical brakes are operated by means of

Hydraulic brakes function on the principle of

If the car is moving on the level road at a speed of 50 km/h has a wheelbase 4 m, a distance of C. G. from ground 800 mm and distance from rear wheels is 1.2 m. Coefficient of friction is 0.8. What is the retardation if the brakes are applied to the front wheels?

If the car is moving on the level road at a speed of 50 km/h has a wheelbase 4 m, a distance of C. G. from ground 800 mm and distance from rear wheels is 1.2 m. Coefficient of friction is 0.8. What is the retardation if the brakes are applied to all wheels?

The car is moving down on the 14° inclined road with horizontal at 36 km/h which is having wheelbase 1.4 m. The C. G. of the car is 0.9 m above the road. The coefficient of friction is 0.75. What is the retardation of the car if the brakes are applied to all the four wheels?

The car is moving up on the 12o inclined road with horizontal at 36 km/h which is having wheelbase 1.4 m. The C. G. of the car is 0.9 m above the road. The coefficient of friction is 0.7. What is the retardation of the car if the brakes are applied to all the four wheels?

If the car is moving on the level road at a speed of 50 km/h has a wheelbase 3 m, a distance of C.G. from ground 700 mm and distance from rear wheels is 1.1 m. Coefficient of friction is 0.7. What is the retardation if the brakes are applied to the rear wheels?
