Click Start Test above to launch a full-length ASE A5 practice test weighted like the real Brakes exam, or drill a single task area — Hydraulic, Power Assist, and Parking; Drum Brakes; Disc Brakes; or Electronic Brake Control. Every question includes a clear explanation so you learn the reasoning, not just the answer.

The ASE A5 Brakes certification is awarded by ASE, the National Institute for Automotive Service Excellence, and validates an automobile technician’s ability to diagnose, service, and repair brake systems — hydraulic, power-assist, and parking brakes, drum and disc brakes, and electronic brake control systems such as ABS, traction control, and electronic stability control.[1]

The computer-based test is delivered by appointment through Prometric and contains 55 multiple-choice questions — 45 scored items plus 10 unscored research questions — with 1 hour and 15 minutes of testing time.[2]

A5 is one of the eight tests (A1-A8) required for ASE Master Automobile Technician status; it is the automotive Brakes credential, not a software, IT, or finance certification. To round out your prep, pair these with our free study guide, flashcards.

ASE A5 is one of the 29 ASE certifications — explore all our ASE practice tests to compare and prep across the whole family.

What Is on the ASE A5 Exam?

The ASE A5 exam covers four task areas: Hydraulic, Power Assist, and Parking Brake Systems (19 scored questions), Drum Brakes (5), Disc Brakes (11), and Electronic Brake Control — ABS, TCS, and ESC (10).[2]

Hydraulic, Power Assist, and Parking Brakes is the largest area and covers the master cylinder, lines and hoses, valves and switches, bleeding and flushing, power-assist (vacuum and hydro-boost) units, and the parking brake, including electronic parking brakes.

Drum Brakes covers drum-brake hydraulic and mechanical diagnosis and servicing shoes, hardware, wheel cylinders, and drums; Disc Brakes covers calipers, pads, rotors, and related service; and Electronic Brake Control covers ABS, traction control (TCS), and electronic stability control (ESC), including wheel-speed sensors and scan-tool diagnosis.

On the real test, the 45 scored questions break down as roughly 19 hydraulic/power-assist/parking, 5 drum, 11 disc, and 10 electronic brake control. Our full 55-question practice test mirrors the same official weighting:

Practice Questions by Area

Use Start Test for a full weighted ASE A5 simulation, or open the hub and pick a single task area to drill your weak spot. After each full exam, your results show a per-area breakdown so you know exactly where to focus — most candidates need the most reps in the areas outside their day-to-day specialty.

What Are the Requirements for ASE A5 Certification?

To earn the ASE A5 Brakes certification you generally need about two years of relevant hands-on work experience, or one year of experience plus a two-year degree in automotive repair; relevant formal training can substitute for up to one year of the experience requirement.

You may take and pass the test before you have met the experience requirement — ASE will hold your result and issue the certificate once you document the required experience.[1] There is no separate education prerequisite simply to sit for the exam.

Register and manage your experience documentation through your myASE account at myASE.com.[4]

How Do You Register for the ASE A5 Test?

You register and schedule the ASE A5 test through your myASE account at myASE.com.[4] The current fee is $62 for the test plus a $34 registration fee paid once per order, so a single A5 test costs about $96; you can add other tests to the same order under the one registration fee.[3]

After you register, you schedule your appointment at a Prometric computer-based testing center, and you typically have 90 days from purchase to test. If you fail, you must wait 30 days before retaking, and you pay the test fee again.

Review ASE’s current Dates, Fees & Test Times page for exact pricing and scheduling rules, as fees can change.

What Is the Passing Score for the ASE A5?

There is no fixed passing percentage for the ASE A5 — raw scores are converted to a scaled score, and the passing standard is set for each test by a panel of automotive subject-matter experts.[2] That keeps the bar consistent even as question difficulty varies between test forms.

Only 45 of the 55 questions count toward your score; the other 10 are unscored research questions ASE is evaluating for future tests, and they are not identified during the exam.

Your score report shows whether you passed and breaks down performance by task area so you can focus study if you need to retake. It is your overall scaled score, not any single task area, that determines pass or fail.

How Hard Is the ASE A5?

The ASE A5 test is moderately challenging and very hands-on. The questions are written by working technicians and focus on practical diagnosis and repair rather than textbook theory, so the difficulty comes from recognizing the correct diagnostic step or repair procedure for a given symptom.

Many items use the “Technician A / Technician B” format that rewards careful reading.

The hydraulic and power-assist section carries the most weight and rewards a strong grasp of master-cylinder, valve, and power-booster diagnosis, while the growing electronic brake control section (ABS, TCS, ESC) requires comfort with wheel-speed sensors and scan-tool diagnosis — an area worth extra review if your work is mostly pad-and-rotor jobs.

The takeaway: ASE does not publish an official first-time pass rate, but because almost two-thirds of the scored questions fall under hydraulic/power-assist/parking brakes and disc brakes, technicians solid on master-cylinder and hydraulic diagnosis, disc service, and electronic brake control tend to perform best. Candidates who do not pass must wait 30 days before retaking and pay the test fee again.

What to Expect on Exam Day

The ASE A5 is a computer-based exam delivered by appointment at a Prometric testing center.[2] Arrive early to check in and bring valid, unexpired government-issued photo ID whose name matches your ASE registration. You’ll store phones and personal items as directed; no notes are allowed.

After a short tutorial, you have 1 hour and 15 minutes to answer 55 multiple-choice questions. Because items are job-based and span all four task areas, pace yourself and don’t over-invest in any one question — flag and return as needed.

Having simulated the full timing with practice tests makes that clock feel routine.

How to Use This ASE A5 Practice Test

  • Recreate exam conditions. Take the full test timed, with no notes.
  • Diagnose, then drill. Use a full ASE A5 simulation to find weak areas, then drill them.
  • Own hydraulic diagnosis. The largest section rewards master-cylinder and power-booster reasoning.
  • Brush up on ABS/TCS/ESC. Electronic brake control is a common weak spot.
  • Learn the why. Read every explanation — understanding beats memorizing.

Why Get ASE A5 Certified?

The ASE A5 signals to shops, employers, and customers that you can diagnose and repair brake systems competently — from hydraulics and power assist to drum, disc, and electronic brake control work.[1] A5 is also one of the eight tests required for ASE Master Automobile Technician status, a benchmark that opens doors and raises earning potential. These free ASE A5 practice tests are the most efficient way to get exam-ready.

Conclusion

Passing the ASE A5 comes down to mastering hydraulic and power-assist diagnosis while keeping up with the growing electronic brake control section. Use this free ASE A5 practice test to find your weak areas, drill them to mastery, and reinforce them with our study guide, flashcards so you walk in confident on test day.
