ASE B5 Domain 3: Brakes Welcome to your ASE B5 Domain 3: Brakes 1. ASE B5: Brakes In a split-diagonal brake system, what happens if there is a failure in the front brake circuit? A. Only one front wheel loses braking power B. Both front wheels lose braking power C. One front and one diagonally opposite rear wheel lose braking power D. The entire braking system becomes inoperative None 2. ASE B5: Brakes What is the primary purpose of a proportioning valve in a braking system? A. To equalize pressure between front and rear brakes B. To reduce hydraulic pressure to the rear brakes during heavy braking C. To increase hydraulic pressure to the front brakes D. To balance left and right brake pressures None 3. ASE B5: Brakes What is the cause of a spongy brake pedal in a hydraulic brake system? A. Worn brake pads B. Air in the hydraulic system C. Faulty master cylinder D. Overheated brake fluid None 4. ASE B5: Brakes In an Anti-lock Braking System (ABS), what is the function of the wheel speed sensor? A. To measure the speed of each wheel B. To control the brake fluid pressure C. To activate the ABS pump D. To balance the brake force among all wheels None 5. ASE B5: Brakes What is the typical cause of uneven brake pad wear in a disc brake system? A. A leaking brake line B. A stuck brake caliper piston C. Worn brake rotors D. Faulty ABS module None 6. ASE B5: Brakes How does an electronic parking brake EPB system primarily differ from a conventional handbrake? A. It uses hydraulic pressure instead of a cable B. It operates only on the front wheels C. It is activated electrically rather than manually D. It uses a separate set of brake pads None 7. ASE B5: Brakes What is the effect of a warped brake rotor on a vehicle's braking performance? A. Reduced braking power B. Increased stopping distance C. Pulsation in the brake pedal during braking D. Continuous dragging of brakes None 8. ASE B5: Brakes In a braking system, what is the role of the master cylinder reservoir? A. To store brake fluid B. To pressurize the brake fluid C. To adjust the brake fluid temperature D. To filter the brake fluid None 9. ASE B5: Brakes What is the primary function of a brake booster in a vehicle? A. To increase the braking force applied by the driver B. To adjust the brake pad position C. To regulate brake fluid pressure D. To cool down the brake system None 10. ASE B5: Brakes What is a common symptom of a faulty brake fluid pressure sensor in an ABS system? A. ABS light on the dashboard B. Squealing brakes C. Brake pedal vibration D. Increased fuel consumption None 1 out of 10 Time is Up! Time's up
