ASE G1 Domain 5: Brakes Welcome to your ASE G1 Domain 5: Brakes 1. ASE G1: Brakes When diagnosing a vehicle with ABS, a technician finds that one wheel consistently locks up during heavy braking. What could be the primary cause of this condition? A. Faulty ABS wheel speed sensor at that wheel B. Air trapped in the brake system C. Uneven tire tread wear D. Defective ABS control module None 2. ASE G1: Brakes A soft brake pedal is noted during initial vehicle start-up, but firms up after the engine is running. The MOST likely cause of this condition is: A. Air in the hydraulic system B. Faulty master cylinder C. Vacuum leak in the brake booster hose D. Defective ABS pump None 3. ASE G1: Brakes If a vehicle's brakes drag and do not release immediately when the pedal is released, the FIRST component to inspect should be the: A. Brake pads for sticking in the caliper B. Master cylinder for residual pressure C. Wheel cylinders for leaks D. Brake pedal linkage for binding None 4. ASE G1: Brakes A vehicle exhibits a squealing noise from the brakes at low speeds. The noise stops when the brake pedal is applied. The MOST likely cause is: A. Glazed brake pads B. Loose brake caliper mounting bolts C. Worn brake pad wear indicators D. Contaminated brake rotor surface None 5. ASE G1: Brakes During a test drive, a pulsation is felt in the brake pedal when the brakes are applied. This symptom is MOST likely caused by: A. Warped brake rotors B. Rear drum out of round C. Faulty ABS modulator D. Collapsed brake hose None 6. ASE G1: Brakes A customer complains that their vehicle pulls to the left when the brakes are applied. The technician should FIRST inspect the: A. Left-side brake hose for blockage B. Right-side caliper for sticking C. Alignment specifications D. Tire pressure on all wheels None 7. ASE G1: Brakes Which of the following is a common reason for brake fluid to appear dark and discolored? A. Overheated fluid from excessive use B. Moisture contamination C. Rubber hose degradation D. All of the above None 8. ASE G1: Brakes A vehicle's rear disc brakes have excessive dust on one side compared to the other. The technician should suspect: A. A seized caliper piston on the cleaner wheel B. A collapsed brake hose on the dirtier wheel C. A faulty proportioning valve D. A malfunctioning parking brake on the dirtier wheel None 9. ASE G1: Brakes What is the MOST likely cause of a brake warning light that illuminates during sharp turns and then turns off soon after? A. Low brake fluid level in the master cylinder reservoir B. A short circuit in the warning light system C. Malfunctioning wheel speed sensors D. Faulty handbrake switch None 10. ASE G1: Brakes Excessive pedal effort is required to stop the vehicle, but the braking performance is adequate. This condition is MOST likely caused by: A. A restricted brake line B. A defective brake booster C. Worn brake pads D. An incorrectly adjusted parking brake None 1 out of 10 Time is Up! Time's up
