What is one of the main purposes of a braking system?
To increase the vehicle's speed
To stop or slow down the vehicle in a controlled way
To power the vehicle's electrical system
To help the engine run cooler
What type of energy transfer occurs in a braking system?
Chemical energy to electrical energy
Heat energy to kinetic energy
Kinetic energy to heat energy
Electrical energy to mechanical energy
What effect does air in the hydraulic braking system have?
No effect
It creates more braking force
It increases pedal travel and reduces braking force
It will cause the handbrake to have less effort
What is the most common operating system used in modern vehicles to operate the brakes?
Air system
Mechanical system
Hydraulic system
Combination of air and mechanical
What is the name of the component that is used to create the pressure in the brake fluid when the brake pedal is pressed?
Caliper
Brake drum
Master cylinder
Wheel cylinder
A mechanical braking system is commonly found on a vehicle as a parking or handbrake.
True
False
Air braking systems are typically found on which types of vehicles?
Motorcycles
Small passenger cars
Sports cars
Heavy vehicles such as lorries and buses
What are the two most common designs of braking systems?
Air brake and Mechanical brake systems
Disc and drum brake systems
Hydraulic brake and Mechanical brake systems
Servo-assisted and Non-servo-assisted systems
A brake disc is generally made from which material? (There may be multiple answers)
Aluminium
Cast iron
Plastic
Stainless steel
In a hydraulic braking system, brake fluid travels from the master cylinder to the braking components at each wheel through what?
Wire cables
Springs
Brake pipes
Levers
The self-adjusting action in a disc brake system is designed to maintain a working air gap between the brake pad and the brake disc.
True
False
What is the function of a servo unit in a braking system?
It provides a vacuum to the engine.
It increases the force applied on the brake pedal.
It releases the handbrake.
It lubricates the brake components.
Which drum brake arrangement has a 'self-servo effect' that allows for extra braking power?
Twin leading
Leading-trailing
Single acting
Double acting
What is the minimum legal brake pad thickness as set out by the DVSA?
5 mm
3 mm
1.5 mm
1 mm
What does the DOT rating on brake fluid usually refer to?
The colour of the fluid
The country of origin
The boiling point and resistance to moisture
The price of the fluid
What are metal brake pipes usually made from? Select all the correct answers.
Steel
Copper or copper-nickel
Rubber
Plastic
The anti-lock braking system (ABS) is controlled by:
A mechanical linkage
Engine vacuum
The brake pedal alone
Electronics
A vehicle's handbrake is used to stop a moving vehicle.
True
False
Why do vented discs aid in heat removal?
They are made of a different material.
They have vents or slots between the disc surfaces.
They are painted with a special heat-resistant paint.
They are smaller than solid discs.
Which of the following diagrams shows a diagonal split hydraulic layouts ?
“The boiling point of brake fluid must be lower than the brake operating temperature (in degrees Celsius).” Is this statement true or false?
True
False
What is a brake fluid that absorbs water known as?
Hydrolastic
Microscopic
Hygrophobic
Hygroscopic
The main difference between D.O.T. 3 and D.O.T. 4 brake fluid is that:
D.O.T. 4 has a higher boiling point (in Celsius).
D.O.T. 4 has a lower boiling point (in Celsius).
D.O.T. 4 is thicker.
D.O.T. 4 is thinner.
What is the primary function of brake fluid in a vehicle's braking system?
To enhance the vehicle's fuel efficiency.
To cool the brakes during operation.
To create hydraulic pressure
To lubricate the brake components.
How often should you typically change your car’s brake fluid?
Every 2 years
Every 5 years
Only when the brakes feel spongy
Every 6 months
What happens if brake fluid absorbs moisture over time?
Brake fluid becomes more effective and enhances braking performance.
Moisture absorption has no impact on brake fluid or braking systems.
Brake fluid can lose effectiveness and lead to brake failure due to lower boiling point and corrosion.
Brake fluid will turn into a solid and block the brake lines.
What should you do if you spill brake fluid on your car's paint?
Use a strong solvent to remove it immediately.
Rinse with water, wash with soap, and apply wax.
Leave it as is, it will dry on its own.
Ignore it, brake fluid doesn't damage paint.
Why is brake fluid important?
Brake fluid is used to clean the car's exterior.
Brake fluid is important because it enables the hydraulic brake system to function effectively, ensuring safe braking.
Brake fluid is important for engine lubrication.
Brake fluid is primarily a coolant for the transmission.
Can I mix different types of brake fluid?
Yes, it's safe to mix brake fluids.
You can mix any type of brake fluid without issues.
Mixing brake fluids can improve performance.
No, you should not mix different types of brake fluid.
How do I check the brake fluid level?
Check the tyre pressure instead.
Inspect the engine oil level.
Look for leaks under the car.
To check the brake fluid level, locate the reservoir and ensure the fluid is between the 'MIN' and 'MAX' markings.
What happens if brake fluid is contaminated?
Brake fluid contamination has no effect on vehicle safety.
Contaminated brake fluid enhances the lifespan of brake components.
Contaminated brake fluid improves braking performance.
Contaminated brake fluid can cause brake failure and reduced braking efficiency.
Is brake fluid toxic?
No, brake fluid is safe to handle.
Brake fluid is non-toxic and environmentally friendly.
Brake fluid is only harmful in large quantities.
Yes, brake fluid is toxic.
How can I tell if my brake fluid is dirty?
Brake fluid is clean if it is bright yellow.
Brake fluid is dirty if it smells sweet.
Brake fluid is always clear and transparent.
Brake fluid is dirty if it is dark, cloudy, or contains particles.
