LV04 Wheels, Tyres, Brakes, Steering & Suspension.

What is the most common form of steering mechanism?

• Rack and pinion

• Recirculating ball

• Worm and sector

• Hydraulic power

To satisfy the MOT regulations the minimum braking efficiency for the foot-brake must not be:

• Less than 50%

• Less than 60%

• Less than 70%

• Less than 80%

In relation to check and adjust the front wheel alignment which of the following is NOT true?

• Toe-in increases tire wear

• Toe-out improves stability

• Camber affects cornering

• Caster affects steering effort

An offside brake caliper piston seized in the off position may cause the:

• Vehicle to pull to left

• Brakes to overheat

• Brake pedal to feel spongy

• Vehicle to pull to right

In relation to vehicle behaviour during cornering 'oversteer' is when the:

• Front wheels lose grip

• Rear wheels lose grip

• Vehicle understeers

• Vehicle maintains grip

Steering wheel shake that gets worse as the speed increases is most likely:

• Wheel imbalance

• Brake disc warp

• Tire pressure issue

• Suspension fault

The Ackerman steering layout produces:

• Parallel wheel alignment

• Toe-in during turns

• Toe-out during turns

• Increased tire wear

A customer complains that their vehicle pulls to the left during braking. One possible cause is

• Incorrect wheel alignment

• Uneven brake pad wear

• Low tire pressure

• Faulty suspension

The legal limit for car tread depth is:

• 1.6 mm

• 2.0 mm

• 2.5 mm

• 3.0 mm

A vertical movement of the body at the front then the back in turn is called

• Pitch

• Roll

• Yaw

• Bounce
