If the front road wheel is set to tilt inwards at the top it has a:

• negative castor

• positive camber

• negative camber

• positive castor

After rectifying an engine fault you need to road test the customer's vehicle. Before you start the test it is essential that you:

• check the vehicle's tyre pressures, oil level and windscreen washer fluid

• complete the job card with all details concerning the vehicle repair

• ensure your work bay is tidy and all tools have been put away

• check that you hold the correct driver's license for the vehicle

During a vehicle inspection you discover that the tread on the front tyres is 'feathering'. This probably indicates that:

• the wheel alignment is incorrect

• the tyre pressures are incorrect

• the swivel pin inclination is wrong

• the power steering is defective

A pulse generator is most commonly found in:

• a fuel system

• an electronic ignition system

• a transmission system

• a chassis ECU

The regulated voltage of an alternator is stated as 13.6 to 14.6 volts at 3000 rpm with the headlamps on. This would indicate that the tolerance is:

• 13.6 volts

• 2.6 volts

• 1.6 volts

• 1 volt

An 'aural' vehicle inspection involves:

• conducting a visual inspection

• carrying out a functional check

• checking component clearance

• listening for unusual noises

The purpose of the brake servo fitted to a car's braking system is to:

• assist the driver's pedal effort

• improve the braking friction

• increase the braking efficiency

• increase the pedal leverage

The tension of an alternator drive belt is checked by:

• measuring maximum voltage across the battery at 2000 rev/min

• measuring the deflection of the belt at its longest point

• measuring the output current when under electrical load

• measuring the rotation force using a spring balance gauge

Which of the following is not likely to be part of the checks made on the windscreen wiper operation during routine vehicle maintenance?

• Inspecting the condition of the wiping surfaces of the rubber blades

• Checking for abnormal noise during the wiping action on a wet screen

• Checking the effectiveness of the wiping action on a wet screen

• Checking the current draw made by the wiper motor during operation

A cut more than 25mm or 10% of the selection width which exposes the casing cords on a tyre:

• is repairable by patching

• makes it illegal

• is only suitable for off road use

• can be safely plugged
