One acceptable method of cleaning metal components on drum brakes is the use of a:

• High-pressure air supply

• Special cleaning fluid

• Soft nylon brush

• Stiff wire brush

The main health risk associated with overhauling drum brakes, is the possibility of:

• Contact with oil

• Contact with grease

• Inhaling brake fluid vapour

• Inhaling asbestos dust

Which pair of the following instruments is most suitable for finding the internal diameter of a brake cylinder?

• Internal calliper and rule

• Dividers and rule

• Odd-legs and micrometer

• Feeler gauge and micrometer

The main purpose of a suspension damper is to:

• Allow for excess load

• Limit the maximum travel of the suspension

• Maintain vehicle height under load

• Absorb the movement energy of the spring

An independent suspension system is one in which:

• There are two different forms of spring to suit light and heavy loads

• Two beam axle suspension units act independently of each other

• Laminated springs are employed on each wheel

• The movement of each wheel has little effect on any of the other wheels’ movements

One advantage of independent suspension compared with fixed beam suspension is that it:

• Extends tyre life considerably

• Improves the ride characteristics

• Increases the load-carrying capacity

• Allows coil springs to be fitted

A health hazard associated with brake lining dust is:

• Dermatitis

• Skin cancer

• Asbestosis

• Asphyxia

This illustration shows the profile of a suspension spring. The type shown is:

• Laminated

• Single-leaf

• Multi-leaf

• Torsion bar

When dismantling a suspension system the MOST important safety aspect that must be observed is to:

• Ensure that the suspension is well lit

• Use both bottle jack and stands

• Ensure that the force exerted by the spring is contained

• Check the condition of the suspension components and floor surface

During a routine interim service, it is noticed that the dust covers on the track rod ball joints are split and perished. The correct procedure is to:

• Replace the ball joints

• Fit new dust covers and pack with grease

• Repair the dust covers with plastic tape

• Do nothing until the main service
