What does 'hydraulics' mean?
Absorbs water from the atmosphere
Operated by a liquid
The study of tidal water movement
Types of fast boats that run on aerodynamic blades
Which wheels does the handbrake normally operate on?
The front wheels only
All four wheels equally
The rear wheels only
One front wheel and one rear wheel for safety
Which of these answers is true?
Fluids are compressible
Fluids are compatible
Fluids are incompatible
Fluids are incompressible
In a simple hydraulic jack, how many non-return valves are there?
None in a simple system
One in a simple system
Only two-way valves are used in a simple system
Two in a simple system
What does the acronym SAE stand for?
Society of Automotive Engineers
Specialized Automotive Equipment
Standards And Equivalences
Society of Artisans in Engineering
The property of a liquid to absorb water from the atmosphere is named:
Hydroscopic
Hydrodynamic
Hygroscopic
Hyperallergic
Which of these answers does not describe a part of a standard hydraulic car braking system?
Servo
Waste Gate
Primary Piston
Compensating Port
If a car is going to be designed with both disc and drum brakes, which of these answers is true?
It is not good practice to have discs and drums on the same car
Drums at the front and discs at the rear
Disc on the left, drum on the right at the front and disc on the right, drum on the left at the rear
Discs at the front and drums at the rear
In a hydraulic brake master cylinder, what is the purpose of the primary piston?
To supply pressurised brake fluid to one brake line
To supply low pressure brake fluid to the secondary piston
To supply pressurised brake fluid to all brake lines equally
To return brake fluid to the reservoir when the brakes are released
Having more than one brake line in a braking system for safety is usually known as:
Duplex-line system
Twin-flow system
Dual-line system
Bypass system
If the area of the piston in the master cylinder is 10 sq mm and the area of the piston in the brake caliper is 20 sq mm, which of these answers is true for the caliper?
The pressure will be reduced and the distance travelled increased
The pressure will be increased and the distance travelled will be increased
The pressure will be reduced and the distance travelled will be decreased
The pressure will be increased and the distance travelled will be decreased
Which of these system layouts is not a common or usual one for automotive brakes?
Front /rear split
Left/right split
Diagonal split
None of these
In a brake servo, the diaphragm assists braking by being partly:
Pulled by a vacuum from the exhaust manifold
Pulled by pressure from the inlet manifold
Pulled by a vacuum from the inlet manifold
Pulled by pressure from the exhaust manifold
Some vehicles use a vacuum pump to operate the servo because:
Some engines such as diesels do not produce vacuum in the usual way
They produce too much vacuum when slowing down
It is more efficient than other systems
It saves wasting vacuum that could be used to power other systems
Which of these answers is correct in relation to most light vehicle hydraulic braking systems?
They use telescopic pipes to allow for suspension and steering movements
They use rigid pipes for strength and longevity
They use fibre-optic cables for reliability and fast transmission of braking forces
They use a mixture of rigid and flexible pipes and hoses
