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 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

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

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
