Vehicle Repair Quiz

Failure to record onto the job card the full amount of time you have spent repairing a vehicle will:

• increase company costs and increase company profits

• reduce the customer's charges and reduce company profits

• reduce company costs and increase company profits

• increase the customer's charges and reduce company profits

Which of the following faults could be caused by worn shock absorbers?

• Increase in braking distance

• Poor vehicle acceleration

• Reduced road spring oscillation

• Decrease in braking distance

A driver complains of steering wheel 'shimmy' that gets worse as the vehicle's speed increases. This most likely indicates:

• the tyre pressures are too high

• the front wheels need balancing

• the wheel alignment needs adjusting

• the shock absorbers need replacing

In relation to steering geometry 'Negative Offset' is produced when the:

• centre lines through both steering arms intersect at a point just in front of the rear axle

• slip angles of the rear tyres are larger than the slip angles of the front tyres

• centre line through the swivel pin intersects the centre line of the wheel below ground level

• centre line through the swivel pin intersects the centre line of the wheel above ground level

The presence of air in a hydraulic braking system will cause:

• a very 'spongy' brake pedal during braking

• corrosion of the brake lines and pistons

• a significant reduction in braking efficiency

• the brake fluid to boil under prolonged braking

In vehicle suspension what does the term 'dive' refer to?

• The dipping and rising of the vehicle on uneven road surfaces

• The lifting of the front of the vehicle during acceleration

• The leaning movement of the body when turning

• The dipping of the front of the vehicle during braking

In relation to steering, 'oversteer' is produced during cornering when the:

• slip angles of the rear tyres are smaller than the slip angles of the front tyres

• slip angles of the front tyres are the same as the slip angles of the rear tyres

• slip angles of the rear tyres are larger than the slip angles of the front tyres

• rear wheels of a car are carrying much less load than the front wheels

Which of the following faults will change the camber angle?

• Very high tyre pressures

• Unbalanced front wheels

• A buckled front wheel

• Incorrect toe setting

ONE advantage of alloy road wheels compared with steel road wheels is they:

• increase unsprung weight

• reduce unsprung weight

• are cheap to manufacture

• reduce heat transfer

In relation to steering geometry, the purpose of the 'castor angle' is to:

• allow for the deflection of the wheels

• provide self centering of the steering

• provide toe-out on turns when cornering

• provide centre point steering layout
