A current guide to the ASE A5 format, 45 scored-question blueprint, Prometric test-center delivery, hydraulic, disc, drum, ABS, TCS, ESC, and parking brake objectives.
ASE A5 is a brake-system diagnosis and repair exam. The largest domain is hydraulic, power assist, and parking brake systems, but the test also expects practical judgment around drum brakes, disc brakes, electronic brake controls, and stability-related complaints.
Use these official structure points to keep A5 prep aligned with the ASE Automobile & Light Truck study guide.
A5 is part of ASE Automobile & Light Truck Certification Tests for cars, SUVs, and light-duty trucks up to Class 3.
The A5 certification appointment has 55 questions in 1 hour 15 minutes, including 45 scored questions plus unscored research questions.
ASE certification requires passing the test and submitting appropriate hands-on work experience.
ASE credentials are valid for five years; the A5 recertification test is shorter at 23 questions and 30 minutes.
Hydraulic, power assist, and parking brake systems are 19 scored questions, or 43% of the test.
Disc brakes are 24%, ABS/TCS/ESC is 22%, and drum brakes are 11% of the scored blueprint.
The largest A5 domain covers hydraulic, power assist, and parking brake systems, so candidates should practice master cylinder faults, line and hose inspection, valve diagnosis, bleeding, leak testing, brake fluid handling, booster checks, and parking brake operation.
Disc and drum brakes create different clues around noise, pulling, dragging, pedal pulsation, grabbing, pad or shoe wear, caliper movement, wheel cylinders, rotor runout, drum measurements, and brake hardware.
ABS, traction control, and electronic stability control questions may involve warning lights, DTCs, wheel speed sensors, yaw and steering angle sensors, module initialization, wiring faults, and vehicle modification effects.
A5 rewards correct service order: inspect, measure, compare to specification, repair or replace, bleed or initialize when required, road test, and verify the complaint is resolved.

ASE A5 Brakes is part of the Automobile & Light Truck Certification Tests for technicians who diagnose, service, and repair cars, SUVs, and light-duty trucks up to Class 3. ASE lists A5 as 45 scored questions, with 55 total questions in the certification appointment because certification tests include additional unscored research questions; the testing time is 1 hour 15 minutes. Certification also requires appropriate hands-on work experience, and credentials must be renewed every five years. The official A5 blueprint covers Hydraulic, Power Assist, and Parking Brake Systems Diagnosis and Repair (19 scored questions, 43%), Drum Brake Diagnosis and Repair (5, 11%), Disc Brake Diagnosis and Repair (11, 24%), and Electronic Brake Control Systems including ABS, TCS, and ESC Diagnosis and Repair (10, 22%). Preparation should emphasize master cylinders, lines and hoses, valves, bleeding, brake fluid, vacuum and hydro-boost assist, electronic parking brakes, drum hardware, disc calipers and rotors, wheel bearings, rotor thickness and runout, ABS/TCS/ESC sensors, scan tool diagnosis, DTCs, module setup, and interrelated stability or collision-mitigation systems.
ASE lists A5 as 45 scored questions, while the certification appointment contains 55 total questions because additional unscored research questions are included.
The A5 certification testing time is 1 hour 15 minutes.
The scored blueprint covers hydraulic, power assist, and parking brake systems; drum brakes; disc brakes; and electronic brake control systems including ABS, TCS, and ESC.
Hydraulic, power assist, and parking brake systems are the largest domain at 43% of the scored test.
Yes. Passing A1 through A8 and meeting the experience requirement earns ASE Master Automobile Technician status; A5 also pairs with A4 as part of the X1 Undercar Specialist prerequisite path.
Anchor study time to the four A5 domains, especially the 43% hydraulic, power assist, and parking brake section.
Practice low pedal, spongy pedal, hard pedal, pedal fade, brake pull, dragging brakes, lockup, vibration, and increased stopping distance scenarios.
Work through rotor thickness, lateral runout, drum diameter, wheel bearing adjustment, line flare rules, pressure tests, and electronic sensor signals.
Run 55-question timed practice blocks in 75 minutes and revisit flagged electronic-control questions after the first pass.
Use the guide to self-serve, or talk to a coordinator if you need help mapping timelines, official requirements, or troubleshooting day-of logistics.
