ASE A5 Brakes Practice Test

66. A vehicle pulls hard to the right while braking. Which of the following is causing this condition?

  • A. A seized left front brake caliper piston.
  • B. A restricted right front brake line.
  • C. Sticking right front caliper slide pins.
  • D. Worn brake pads.

66.

Answer A is correct. A seized left front caliper piston will cause the vehicle to pull to the right while braking.

Answer B is wrong. A restricted right front brake line results in brake drag and a pull to the right.

Answer C is wrong. Seized or sticking right front brake caliper slides/slide pins will cause the car to drift right while driving forward and pull left while braking.

Answer D is wrong. Brake drag results in an overheated brake unit, poor fuel mileage, and a drift or pull to the side with the dragging brake.

67. Which of the following can result from over-tightening a wheel?

  • A. Stud damage.
  • B. Brake rotor damage.
  • C. Both A and B
  • D. Neither A or B

67.

Answer A is wrong. Wheel studs can become stripped if over-tightened.

Answer B is wrong. Over-torquing a wheel can result in brake rotor warpage.

Answer C is correct. Both A and B are correct.

Answer D is wrong. Both A and B are correct.

68. The front brake pads on a vehicle with a quick take-up master cylinder need replacement. They were recently replaced. Technician A says this is a low-drag brake system. Technician B says the master cylinder's quick take-up valve could be sticking. Who is correct?

  • A. Technician A
  • B. Technician B
  • C. Both A and B
  • D. Neither A or B

68.

Answer A is wrong. Both technicians are correct. This type of master cylinder is used with low-drag brake calipers. It is distinguishable by a large diameter piston and primary low-pressure bore located at the back or push rod end of the master cylinder.

Answer B is wrong. The quick take-up master cylinder provides more brake fluid volume to add space between the pads and the rotor. They are fuel-efficient.

Answer C is correct. Both technicians are correct.

Answer D is wrong. Both technicians are correct.

69. Technician A says to use the scan tool's bidirectional function to test the bulb of an inoperative parking brake warning light. Technician B says a scan tool may be required to retract the piston of an electronic parking brake caliper before servicing the rear brakes. Who is correct?

  • A. Technician A
  • B. Technician B
  • C. Both A and B
  • D. Neither A or B

69.

Answer A is wrong. Commanding a warning light with a bidirectional scan tool is an excellent way to test a bulb in the instrument panel.

Answer B is wrong. Most modern electric parking brakes have actuators bolted to the rear calipers. Use the in-dash navigation or a bidirectional scan tool to command the system to retract the parking brake before servicing the rear brakes.

Answer C is correct. Both Technicians are correct.

Answer D is wrong. Both Technicians are correct.

70. The red brake warning light on the instrument panel illuminates when the brakes are applied. Which of the following results in this condition?

  • A. A burned brake light bulb.
  • B. Air in the hydraulic brake system.
  • C. A damaged wheel speed sensor tone ring.
  • D. An open in the brake switch circuit.

70.

Answer A is wrong. Some vehicles have a brake light failure indicator. This is typically amber. A burned brake light bulb will not illuminate the red brake warning light.

Answer B is correct. The red brake warning light will illuminate if there's a loss in pressure in one of the two hydraulic brake circuits if the parking brake is engaged or if the key is in the ON/RUN position.

Answer C is wrong. If the ABS controller senses a damaged tone ring by an erratic wheel speed sensor signal, it will illuminate the amber ABS light.

Answer D is wrong. The brake lights would not illuminate if the brake switch has an open circuit.
