HV04 Test 5

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

• Increase stopping distance

• Cause brake failure

• Reduce braking efficiency

• Improve braking performance

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

• Toe angle

• Camber angle

• Caster angle

• Kingpin angle

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

• Increased braking force

• Brake fade

• Improved pedal feel

• Reduced stopping distance

Over inflated tyres will wear greater on the:

• Inside edge

• Outside edge

• Center

• Tread blocks

To satisfy the heavy vehicle testing regulations the minimum braking efficiency for the footbrake must NOT be:

• Less than 50%

• More than 75%

• Exactly 60%

• Below 70%

In relation to steering geometry 'Negative Camber' is when the:

• Top of the wheel leans out

• Bottom of the wheel leans in

• Top of the wheel leans in

• Bottom of the wheel leans out

If the front wheel alignment is incorrect the:

• Vehicle will pull to one side

• Brakes will overheat

• Steering will be lighter

• Tyres will last longer

How many magnetic valves does this ABS solenoid valve have?

• One

• Two

• Three

• Four

A 'live' rear axle arrangement:

• is a type of independent suspension

• is a type of non-independent suspension

• does not transmit power to the wheels

• is used only in front-wheel-drive vehicles

What does the wheel sensor in an anti-lock braking system (ABS) sense?

• Wheel speed

• Brake fluid level

• Tire pressure

• Engine temperature
