#1
What is a common symptom of brake pad wear?
Squealing or grinding noises
ExplanationSquealing or grinding noises indicate worn brake pads.
#2
Which type of brake system uses hydraulic pressure to transmit force?
Hydraulic brake system
ExplanationHydraulic brake systems use hydraulic pressure for braking force transmission.
#3
What is the purpose of the parking brake (handbrake) in a vehicle?
To hold the vehicle stationary when parked
ExplanationThe parking brake secures the vehicle in a stationary position when parked.
#4
What is the purpose of the brake warning light on the dashboard?
To warn of low brake fluid level or brake system malfunction
ExplanationThe brake warning light alerts to low brake fluid levels or brake system malfunctions.
#5
What does ABS stand for in the context of brake systems?
Anti-lock Braking System
ExplanationABS stands for Anti-lock Braking System.
#6
What is the purpose of brake fluid in a hydraulic brake system?
To transfer hydraulic pressure to actuate the brakes
ExplanationBrake fluid transfers hydraulic pressure to activate the brakes in hydraulic systems.
#7
What component converts brake pedal pressure into hydraulic pressure in a brake system?
Master cylinder
ExplanationThe master cylinder converts brake pedal pressure into hydraulic pressure.
#8
What is the purpose of a brake rotor in a disc brake system?
To convert kinetic energy into heat
ExplanationBrake rotors convert kinetic energy from motion into heat energy during braking.
#9
In a drum brake system, which component presses against the brake drum to generate friction?
Brake shoes
ExplanationBrake shoes press against the brake drum to create friction in drum brake systems.
#10
What is brake fade?
A decrease in braking effectiveness under continuous use
ExplanationBrake fade refers to reduced braking efficiency over prolonged use.
#11
What is the correct procedure for bleeding brake lines?
Begin with the brake line farthest from the master cylinder
ExplanationStart bleeding brake lines from the farthest line to the master cylinder for proper air removal.
#12
Which type of brake system relies on an electric motor to actuate the brakes?
Electromagnetic brake system
ExplanationElectromagnetic brake systems use electric motors for brake actuation.
#13
Which of the following is NOT a potential cause of brake pedal pulsation?
Faulty brake booster
ExplanationFaulty brake booster is not a cause of brake pedal pulsation.
#14
What is the purpose of a brake proportioning valve?
To balance brake force distribution between front and rear wheels
ExplanationBrake proportioning valves balance braking force distribution among the wheels.
#15
What is the main advantage of carbon-ceramic brake rotors over traditional steel rotors?
Reduced weight
ExplanationCarbon-ceramic brake rotors offer reduced weight compared to traditional steel rotors.
#16
Which of the following is NOT a symptom of a failing brake booster?
Vibration in the brake pedal
ExplanationVibration in the brake pedal is not a symptom of a failing brake booster.
