1. Describe the steps involved in diagnosing a brake system issue.
The steps involved in diagnosing a brake system issue typically include:
- Taking a detailed history of the vehicle and the symptoms the customer is experiencing.
- Performing a visual inspection of the brake system components, including the pads, rotors, calipers, and lines.
- Testing the brake system’s functionality, including the pedal feel, stopping distance, and brake fluid pressure.
- Using diagnostic tools, such as a brake pressure gauge or a scan tool, to identify any specific issues with the brake system.
2. Explain the difference between disc brakes and drum brakes, and discuss the advantages and disadvantages of each type.
Disc Brakes
- Advantages: Disc brakes are more effective than drum brakes at dissipating heat, which makes them less likely to fade during heavy braking.
- Disadvantages: Disc brakes are more expensive to manufacture and maintain than drum brakes.
Drum Brakes
- Advantages: Drum brakes are less expensive to manufacture and maintain than disc brakes.
- Disadvantages: Drum brakes are less effective than disc brakes at dissipating heat, which makes them more likely to fade during heavy braking.
3. What are the different types of brake fluid, and what are their different properties?
There are three main types of brake fluid: DOT 3, DOT 4, and DOT 5.
- DOT 3: DOT 3 is the most common type of brake fluid. It is a glycol-based fluid that has a boiling point of 230 degrees Celsius (446 degrees Fahrenheit).
- DOT 4: DOT 4 is a higher-performance brake fluid than DOT 3. It has a higher boiling point of 260 degrees Celsius (500 degrees Fahrenheit), and it is more resistant to fading.
- DOT 5: DOT 5 is a silicone-based brake fluid that has a much higher boiling point than DOT 3 or DOT 4 (280 degrees Celsius or 536 degrees Fahrenheit). It is also more resistant to fading and moisture.
4. How do you adjust the parking brake on a vehicle?
The steps involved in adjusting the parking brake on a vehicle typically include:
- Locating the parking brake adjustment mechanism, which is usually located near the rear wheels.
- Tightening the adjustment mechanism until the parking brake pedal has the desired amount of travel.
- Checking the parking brake’s effectiveness by setting the parking brake and trying to move the vehicle.

The signs and symptoms of a failing brake master cylinder can include:
- A spongy or soft brake pedal
- A brake pedal that goes to the floor
- Leaking brake fluid
- Diminished brake performance
6. How do you troubleshoot a brake system that is causing a pulsation in the brake pedal?
To troubleshoot a brake system that is causing a pulsation in the brake pedal, you can:
- Check the brake rotors for warping or uneven wear.
- Check the brake pads for uneven wear or contamination.
- Check the brake calipers for proper operation.
- Check the brake master cylinder for proper operation.
7. What are the different types of brake pads, and what are their different characteristics?

- Ceramic brake pads: Ceramic brake pads are known for their low noise and dust, as well as their long lifespan.
- Semi-metallic brake pads: Semi-metallic brake pads offer good performance and durability, and they are less expensive than ceramic brake pads.
- Organic brake pads: Organic brake pads are made from organic materials, such as rubber and Kevlar. They offer good performance and are less expensive than ceramic and semi-metallic brake pads.
8. How do you inspect and replace a brake caliper?
To inspect and replace a brake caliper, you can:
- Remove the caliper from the vehicle.
- Inspect the caliper for any damage or wear.
- Replace the caliper if it is damaged or worn.

- Solid rotors: Solid rotors are the most common type of brake rotor. They are made from a single piece of metal, and they are less expensive than slotted rotors.
- Slotted rotors: Slotted rotors have slots cut into the surface of the rotor. These slots help to dissipate heat and reduce brake fade.
10. How do you troubleshoot a brake system that is causing a noise when braking?
To troubleshoot a brake system that is causing a noise when braking, you can:
- Check the brake pads for wear or contamination.
