HV04- Test 4

Water collecting in the service brake tanks of a full air brake system will:

• Reduce the volume of air available for braking
• Reduce pressure of air available for braking
• Increase the volume of air available for braking
• Increase the pressure of air available for braking

The steering angle that allows a degree of self centering after cornering is the:

• Caster angle
• Camber angle
• Included angle
• Toe out angle

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

• A very spongy brake pedal during braking
• The brake fluid to boil under prolonged braking
• A significant resuction in braking efficiency
• Corrosion of the brake lines and pipes

Over inflated tyres will wear greater on the:

• Both outer edges of the tread
• Center portion of the tread
• Outer edge of the tread
• Inner edge of the tread

Heavy vehicle testing regulations minimum braking efficiency for football must not be:

• Less than 25%
• Less than 50%
• Less than 100%
• Less than 90%

In relation to steering geometry, Negative camber is when the:

• The wheel tilts inwards at the top
• The kingpin tilts backwards
• The kingpin tilts outwards
• The wheels tilt outwards at the top

If the front wheel alignment is incorrect the:

• Front tyres will feather
• Wheels will not toe out on turns
• Negative offset will change
• Wheels will toe in on turns

A live rear Axle arrangement:

• Is fitted with a final drive
• Has no final drive
• Always has independent suspension
• Has no suspension system

The wheel sensor is an anti-lock braking system (ABS) senses:

• Wheel speed
• Frictional force
• Air pressure
• Braking efficiency

In relation to suspension systems the abbreviation IFS means:

• Individual labour efficiency
• Independent front suspension
• Individual forward suspension
• Independent forward suspension
