Question 1: Checking for vacuum at the booster

Answer:

The process of using a gauge to ensure the brake booster is receiving adequate vacuum for operation.

Question 2: Testing a vacuum power brake booster

Answer:

The process of checking the operation of the brake booster by observing engine idle and pedal response.

Question 3: Contaminated brake fluid

Answer:

Brake fluid that has been contaminated with moisture or debris, affecting braking performance.

Question 4: Warped brake rotors

Answer:

A condition where the brake rotors are not flat, causing uneven braking.

Question 5: Pumping the brake pedal

Answer:

A technique used to test brake systems, often involving multiple presses to build pressure.

Question 6: Faulty master cylinder

Answer:

A malfunctioning master cylinder that can cause low brake fluid levels and braking issues.

Question 7: Improperly adjusted brake shoes

Answer:

A condition where brake shoes are not set correctly, leading to potential braking issues.

Question 8: Leaking wheel cylinder

Answer:

A failure in the wheel cylinder that allows brake fluid to escape, leading to low fluid levels.

Question 9: Contaminated brake fluid

Answer:

A possible reason for the brake pedal slowly going to the floor under normal braking pressure.

Question 10: Air in the brake lines

Answer:

Presence of air in the brake lines that can lead to spongy brake feel and reduced braking efficiency.

Question 11: Drums machined

Answer:

The process of resurfacing brake drums to ensure they are smooth and provide proper braking.

Question 12: Dragging rear brakes

Answer:

The most likely cause after new linings installed and drums machined is a stuck parking brake cable.

Question 13: Stuck parking brake cable

Answer:

A condition where the parking brake cable does not release properly, causing rear brakes to drag.

Question 14: Disconnecting the ABS fuse

Answer:

A method to depressurize an ABS system.

Question 15: Low brake fluid levels

Answer:

A condition observed by a technician indicating a potential issue such as leaking components.

Question 16: Depressurizing an ABS system

Answer:

The proper way includes opening the bleeder valves.

Question 17: Brake pedal pumping test

Answer:

Pump the brake pedal at least 4 times, hold the brake pedal depressed, and start the engine to test the vacuum power brake booster.

Question 18: Pedal slowly goes to the floor

Answer:

The most likely cause is warped brake rotors, contaminated brake fluid, internal leak in the master cylinder, or faulty brake booster.

Question 19: Internal leak in the master cylinder

Answer:

A common cause for the brake pedal going to the floor when normal braking pressure is applied.

Question 20: Normal pad wear

Answer:

The expected reduction in brake pad thickness due to regular use over time.

Question 21: Faulty brake booster

Answer:

A potential issue that could cause the brake pedal to slowly go to the floor during a road test.

Question 22: Depressurizing an ABS system

Answer:

The proper way includes opening the bleeder valves, disconnecting the ABS fuse, pumping the brake pedal at least 25 times with the ignition off, or running the ABS self-diagnostic test.

Question 23: Faulty brake booster

Answer:

A malfunctioning brake booster that can affect the power assist to the brake system.

Question 24: Air in the brake lines

Answer:

A potential reason for low brake fluid levels observed by a technician.

Question 25: Leaking wheel cylinder

Answer:

A likely cause for low brake fluid levels observed during inspection.

Question 26: ABS self-diagnostic test

Answer:

Running this test is one way to depressurize an ABS system.

Question 27: Pumping the brake pedal

Answer:

Pump the brake pedal at least 25 times with the ignition off to depressurize an ABS system.

Question 28: Vacuum check at the booster

Answer:

Check for vacuum at the booster with a gauge to test the vacuum power brake booster.
