Which part of the braking system forms the emergency brake?

• Brake Servo

• Hand brake

• Brake disc

• Wheel cylinder

What is purpose of a tandem master cylinder?

• To ensure enough brake fluid that air does not enter system

• To allow equal pressure to the front wheels

• To enable calipers to clamp brake disc

• In the event of fluid loss 50% of brake will be available

Which of these statements is FALSE?

• Smaller output piston gives smaller force and less travel

• Smaller output piston has more travel but less force

• Larger output piston gives more force but less travel

• Hydraulic fluid does not compress

Pascal's Law states any pressure applied to a fluid in a closed system will:

• transmit that pressure equally in all directions throughout the fluid

• Transmit pressure in one direction only

• Do nothing as fluid cannot be pressurised

• move piston same amount of travel no matter the size

In order to know brake imbalance what must we do?

• Add all of the brake efforts together and divide by car weight

• Add all of the brake efforts together and multiply by car weight

• Subtract the lowest effort from the highest effort, then divide by highest effort

• Subtract the lowest effort from weight and divide by highest effort.

If we had 100% brake efficiency this would mean that:

• The total applied force was equal to the weight of vehicle

• Both front brakes had equal effort

• Both rear brakes had equal effort

• The car is fitted with ABS.

What is the purpose of a reservoir on the brake master cylinder.

• These are only fitted to tandem systems

• They remove air from system

• They stop moisture getting into system

• They provide sufficient fluid to prevent air being drawn into system

The reservoir cap is fitted with a fluid level indicator

• True

• False

A typical car with disc / drum brakes has:

• Drum brakes all round

• Disc brakes all round

• Drum brakes at front & Disc at rear

• Disc brakes at front & Drum on rear
