Braking System and Wheel Mechanics Quiz

The purpose of the braking system is to

• reduce the speed of the vehicle

• transmit drive to the road wheels

• change the direction of the vehicle

• disconnect the drive from the engine

The purpose of the section of the wheel indicated by the arrow is to

• allow the tyre to run flat

• allow the tyre to be removed

• ensure the tyre inflates quickly

• prevent the tyre being punctured

The tool shown is used to

• check tread depths

• balance road wheels

• measure tyre pressures

• remove balance weights

When measuring steering geometry with the aid of turntables, the vehicle must be

• higher at the rear

• on a level surface

• higher at the front

• carrying maximum load

After replacing front discs and pads, a vehicle should be tested for

• hunting when braking

• slipping when accelerating

• wandering when cornering

• pulling up smoothly when braking

One function of a rear suspension damper is to

• stop the spring compressing

• reduce the spring oscillations

• push the tyre towards the road

• hold the swinging arm centrally

Which one of the following steering angles assists the road wheel to travel straight?

• Castor

• Camber

• Ackermann

• Swivel axis inclination

Brake fluid deteriorates over time as it

• solidifies

• evaporates

• absorbs moisture

• becomes more viscous

Compliance bushes fitted to a suspension component are usually made from

• mild steel

• natural rubber

• sintered copper

• synthetic rubber

The main factor affecting vehicle stopping distance is the

• diameter of the master cylinder and wheel cylinders piston

• air and fluid pressure difference across the servo piston

• friction between the tyre tread and the road surface

• maximum pressure acting through the brake fluid
