Exam 1
1. A customer complains of a low brake pedal. Which of the following
is the MOST likely cause?
A. Warped rotors
B. Glazed brake pads
C. Air in the brake lines
D. Worn wheel bearings
,Answer: C
Rationale: Air in the brake system compresses easily, causing a soft or
low brake pedal.
2. Technician A says a seized caliper piston can cause brake drag.
Technician B says a collapsed brake hose can cause the same
symptom. Who is correct?
A. Technician A
B. Technician B
C. Both A and B
D. Neither A nor B
Answer: C
Rationale: Both issues can cause brake drag by preventing the caliper
from releasing fully.
3. Which component converts brake pedal force into hydraulic
pressure?
A. Caliper
B. Brake booster
C. Master cylinder
D. Wheel cylinder
Answer: C
Rationale: The master cylinder generates hydraulic pressure when the
brake pedal is pressed.
,4. What tool is used to measure rotor runout?
A. Dial indicator
B. Micrometer
C. Torque wrench
D. Vernier caliper
Answer: A
Rationale: A dial indicator measures lateral rotor movement (runout).
5. A pulsing brake pedal during braking MOST likely indicates:
A. Worn brake pads
B. Air in the lines
C. Warped brake rotors
D. A seized caliper
Answer: C
Rationale: Warped rotors cause pulsation in the pedal due to uneven
surface contact.
6. Brake fade is most commonly caused by:
A. Cold pads
B. Moisture in fluid
C. Overheating of brake components
D. Vacuum leak
Answer: C
Rationale: Excessive heat reduces the friction between pads and rotors,
causing fade.
, 7. Technician A says worn brake pads can cause rotor damage.
Technician B says pads should always be replaced in axle sets. Who is
correct?
A. Technician A
B. Technician B
C. Both A and B
D. Neither A nor B
Answer: C
Rationale: Worn pads can damage rotors, and pads should be replaced
in pairs for balanced braking.
8. A customer says their vehicle pulls to the right when braking. This
could be caused by:
A. A stuck open thermostat
B. A seized left caliper
C. Low brake fluid
D. Worn control arm bushings
Answer: B
Rationale: A seized caliper on the left side causes uneven braking and
vehicle pull to the right.
9. What is the main function of the proportioning valve?
A. Increase front brake pressure
B. Reduce rear brake pressure during hard braking
