A brake servo (sometimes called a booster) assists the driver by increasing brake fluid
volume
pressure
viscosity
reaction time
Application of the brakes, in a forward moving vehicle, causes weight transference from the
front axle to the rear axle
rear axle to the front axle
vehicles highest point to the lowest point
vehicles lowest point to the highest point
Brake fade is caused by
air in the system
swollen seals in the master cylinder
weak flexible brake hoses
overheating of the brakes
The braking efficiency of a vehicle is a measure of the
mechanical efficiency of the braking system
ease with which the wheels can be made to skid
braking force compared to the weight of the vehicle
coefficient of friction between brake pads and discs
Which of the following is an advantage of disc brakes as compared with drum brakes?
pads are more difficult to change than brake shoes
they dissipate heat more effectively
they are more prone to brake fade
they have no self-servo action
A snail cam is used to adjust the
pads on a disc brake
shoes on a hydraulically operated brake
shoes on a mechanically operated internal expanding brake
clutch operating linkage to the correct free-pedal movement
Self-servo action of a drum brake occurs on the
trailing shoe
front shoe
leading shoe
rear shoe
The type of brake which uses the forward rotation of the drum to assist the application of both brake shoes is described as
mechanical leading and trailing shoe
hydraulic leading and trailing shoe
twin-leading shoe
twin-trailing shoe
It is recommended that brake fluid be changed periodically because it
absorbs moisture
loses it viscosity
causes seals to swell
becomes too thick
It is necessary to bleed air from a hydraulic brake system because air
will expand with heat
cannot be compressed
can be compressed
does not mix with brake fluid
A tandem master cylinder has how many pistons?
1
2
3
4
When braking, a driver notices that the pedal travel has increased but some braking force remains. The braking system fitted to the vehicle is most likely to have
ABS with separate front and rear circuits
a tandem master cylinder
disc brakes on all wheels
power braking
Which one of the following components is fitted between the clutch pressure plate and the flywheel?
pressure pad
driven plate
clutch thrust
release spring
A clutch driven plate is splined to the gearbox:
output shaft
layshaft
clutch pedal
input shaft
The fourth gear ratio of most rear wheel drive light vehicles is
1:1
2:1
3:1
4:1
