Stay off at all times
Stay on at all times
What type of car is this disc used on:
Performance
Family Hatchback
Large saloon
Tractor
What function do the holes in steel wheels perform?
Allow for visual inspection of the brakes
Create a noise under speed
Allow for water movement
Allow air for cooling the brakes
What is increased to allow a greater load for tyres?
Tread
Plies
Rubber
Steel
The load index of a tyre refers to the:
Maximum pressure the tyre can be inflated to
Maximum number of passengers a vehicle can carry
Maximum weight a tyre can carry up to a certain speed
Minimum pressure the tyre should be inflated to
The main factor affecting vehicle stopping distance is the:
Diameter of the master cylinder and the wheel cylinders piston
Air and fluid pressure difference across the servo piston
Friction between the tyre tread and the road surface
Maximum pressure acting through the brake fluid
An over - inflated tyre will:
Reduce tyre life
Increase tyre life
Damage the wheel rim
Damage the tyre valve
The maximum length in millimetres of a cut allowed on the side wall of a tyre is:
15
16
20
25
A spilt brake system refers to a braking system:
With a split pipe
Employs more than one brake fluid circuit
Which feeds fluid to the clutch system hydraulic circuit
With anti-locking brake design features
Weight transfers from the rear to the front of a vehicle during:
Braking
Rebound
Cornering
accelerating
A pulsating brake pedal experienced upon braking at low speeds would indicate:
air in the brakes hydraulic system
excessively worn brake linings
a leaking brake servo unit
Warped or buckled brake disc
Compliance is the term used to describe:
a type of rubber bump stop which forms part of a strut suspension
the flexibility which allows slight distortion of suspension arm bushes
the profile of taper leaf springs or multi-leaf springs
a type of semi trailing arm rear suspension system
Which one of the following will be the most affected by incorrect wheel alignment:
Tyre life
Brake efficiency
Vehicle trim height
Suspension bounce
Ackerman's principle states that the:
Outer wheel turns through a greater angle than the inner wheel during cornering
Inner wheel turns through a greater angle than the outer wheel during cornering
Outer wheel rotates slower than the inner wheel during cornering
Inner wheel rotates faster than the outer wheel during cornering.
Incorrect wheel alignment is often caused by:
Impact with the kerb,
A noisy wheel bearing,
Worn brake pads,
Leaking damper.
Before road testing a vehicle following suspension repairs, the driver must ensure that the:
Vehicle is roadworthy,
Job card is carried in the vehicle, Owners insurance covers testing,
Supervisor gives written permission.
The car has been cleaned
A suspension spring is to be removed from a strut on the bench. The special tool required for the task is a:
Three legged puller,
Spring clamp,
Torx wrench,
Nut splitter.
One disadvantage of directional tyres is that:
They can only be used on vehicles that have alloy wheels fitted,
They are not recommended for use on slippery surfaces,
The wheels cannot be cross rotated as part of routine maintenance procedures,
They cannot be used on vehicles fitted with four wheel drive.
The speed rating of a tyre with 205/55 R18 H markings is:
18
205
H
R
Which one of the following types of tyre has the ply running at 90' to the bead?
Tubeless
Cross-ply
Radial-ply
Bias-belted
When compared with drum brakes, disc brakes:
Dissipate heat more effectively
Have better protection from the road dirt
Are more likely to suffer from brake fade
Increase the sprung weight of the vehicle
The function of an ABS wheel speed sensor is to:
Monitor the speed of the vehicle
Detect direction of wheel rotation
Monitor the brake line pressure
Identify the speed of a road wheel,
The purpose of a residual line pressure in a braking system is that it:
Prevents the brake fluid from travelling to the wheel
Reduces the rate of wear on the brake components
Prevents the reservoir from losing all brake fluid
Maintains an air free system when at rest
The main purpose of a damper unit in a suspension system is to:
Eliminate torsional twist of the chassis or sub frame
Limit the compressive movement of the suspension spring
Prevent energy stored in the springs being converted into heat
Reduce the natural rebound movement of the suspension spring
Suspension dampers reduce road spring
Travel
Tension
Harshness
Oscillations
