LV04 practice paper

To maintain performance and safety requirements it is:

• important to clean the vehicle after servicing

• important that all cars are road tested

• important that all cars must have a MOT

• important to fit replacement parts that meet the original manufacturers specification

The unsprung weight can be reduced by fitting:

• alloy road wheels

• steel road wheel

• larger diameter wheels

• wheel trims

What is the function of item number 7 in the illustration?

• To enable the brakes to be vented

• To transmit the force from the brake fluid to the brake pad

• To enable brake adjustment to be carried out

• To prevent brake squeak when worn

MacPherson strut type suspension has:

• coil springs

• rubber springs

• torsion bar springs

• leaf springs

Hydraulic suspension dampens out spring movement by;

• compressing another spring of a different rate

• forcing oil through valves to slow its movement

• compressing a rubber cone

• forcing air through valves to slow its movement

A rear suspension system consisting of a solid rear axle with a spring and damper at each end is called;

• torsion bar suspension

• non independent rear suspension

• adaptive suspension

• isolastic suspension

ABS operates by?

• Providing enough braking force to lock the rear wheels only

• Providing enough braking force to lock all four wheels

• Providing only enough braking force to each wheel to avoid locking

• Providing enough braking force to lock one wheel only

Adaptive suspension uses

• air damping controlled by a compressor

• driver operated control valves

• manually adjustable friction dampers

• hydraulic damping controlled by sensors, actuators and an ecu

The steering angle which provides a self-centering force to the road wheels is:

• the castor angle

• the swivel pin inclination angle

• the Ackermann angle

• the camber angle

Negative swivel axis inclination is defined as:

• the outward tilt of the swivel axis when viewed from the front of the vehicle

• the forward tilt of the swivel axis when viewed from the side of the vehicle

• the outward tilt of the road wheels when viewed from the front of the vehicle

• the backward tilt of the swivel axis when viewed from the side of the vehicle
