Brake Diagnosis worksheet

What is the purpose of verifying the customer's complaint as mentioned in the lesson objectives for brake diagnosis?

• To determine the serviceability of a drum or rotor

• To establish pedal height, pedal freeplay, and reserve distance

• To convey the importance of verifying the customer's complaint

• To explain the cause of rotor parallelism

Which tool is used to measure hub runout and rotor runout according to the lesson objectives?

• Brake drum micrometer

• On-car brake lathe

• Dial indicator

• Vernier caliper

What is the objective of using a micrometer or vernier caliper in brake diagnosis?

• To establish pedal height, pedal freeplay, and reserve distance

• To measure hub runout and rotor runout

• To determine brake drum diameter and serviceability

• To measure rotor parallelism

What is the purpose of using a brake drum micrometer as per the lesson objectives?

• To phase-match a rotor and hub for minimum rotor runout

• To determine brake drum diameter and serviceability

• To turn a rotor using the on-car brake lathe

• To explain the cause of rotor parallelism

When diagnosing brake problems, what is the first step according to the plan of action provided in the learning material?

• Repair the problem.

• Isolate the cause.

• Verify the customer's complaint.

• Identify the symptoms.

What should you do if the customer's complaint cannot be verified?

• Proceed with the repair based on your expertise.

• Ignore the complaint as it may not be genuine.

• Do some preliminary checks before taking the car out on the road.

• Attempt to find the source of the problem or any other improper things to bring to the customer's attention.

If a customer's car had a previous repair for a similar symptom, what advantage does this give you?

• It allows you to charge more for the service.

• It gives you an advantage in your diagnosis.

• It means you can ignore the current complaint.

• It ensures the car will not have the same problem again.

Before taking the customer's car out for a test drive, what should you ensure?

• That the customer has paid for the service.

• That the car has been cleaned and washed.

• That the car is safe and the pedal does not go to the floor.

• That you have the customer's permission to drive the car.

What should be checked for leaks during preliminary checks before bringing a vehicle in for service?

• Engine oil level and tire pressure

• Brake backing plate, flexible brake hoses, connections, brake tubing, auxiliary valves, master cylinder

• Air filter and battery terminals

• Radiator fluid and windshield wiper fluid

What is adjusted to establish the brake pedal position?

• The brake lining

• The master cylinder

• The push rod

• The brake hoses
