Vehicle Inspection and Repair Procedures

The function of brake calipers in the braking system is to:

• increase the speed of the vehicle

• control the steering of the vehicle

• apply pressure to the brake pads

• monitor the engine temperature

Define 'seized' and 'sticking' brake calipers and explain the difference.

• 'Seized' brake calipers are completely stuck and do not move, while 'sticking' brake calipers move but with difficulty.

• 'Seized' brake calipers move with difficulty, while 'sticking' brake calipers are completely stuck and do not move.

• Both 'seized' and 'sticking' brake calipers are completely stuck and do not move.

• Both 'seized' and 'sticking' brake calipers move but with difficulty.

What are the safety implications of faulty calipers?

• Faulty calipers can lead to inaccurate measurements, affecting safety.

• Faulty calipers have no impact on safety.

• Faulty calipers improve measurement accuracy.

• Faulty calipers are only a minor inconvenience.

Which of the following best explains the operation and common issues of Sliding/Floating Calipers?

• They use a single piston and can suffer from uneven pad wear.

• They use multiple pistons and are immune to pad wear issues.

• They are primarily used in drum brakes and have no common issues.

• They operate electrically and have frequent electronic failures.

Discuss the design and potential problems of Fixed Calipers.

• Fixed calipers are designed to be adjustable and may face issues with uneven wear.

• Fixed calipers are non-adjustable and may face issues with uneven wear.

• Fixed calipers are designed to be adjustable and do not face any issues.

• Fixed calipers are non-adjustable and do not face any issues.

Which of the following lists the components of a caliper and their functions?

• Body, Jaws, Locking Screw - Measure dimensions

• Body, Scale, Pointer - Measure weight

• Body, Needle, Dial - Measure temperature

• Body, Lens, Light - Measure brightness

The importance of proper sealing and inspection of the brake hose connection is:

• To ensure the brake system functions correctly and safely.

• To improve the vehicle's fuel efficiency.

• To enhance the vehicle's speed.

• To reduce the vehicle's weight.

Identify the common symptoms of seized/sticking calipers.

• Increased stopping distance

• Unusual noise when braking

• Vehicle pulling to one side

• All of the above

Explain how to distinguish between seized/sticking calipers and other brake problems.

• By checking the brake fluid level

• By inspecting the brake pads for uneven wear

• By listening for unusual noises when braking

• By feeling for vibrations in the steering wheel

The relationship between brake pads and caliper function is:

• Brake pads are part of the caliper function, providing the necessary friction to stop the vehicle.

• Calipers are part of the brake pads, providing the necessary friction to stop the vehicle.

• Brake pads and calipers function independently of each other.

• Calipers are responsible for the vehicle's acceleration, while brake pads are for stopping.
