ASE A5 Brakes practice test
The A5 test runs from hydraulics to ABS: pedal-feel diagnosis, pulls and pulsation, boosters, and electronic brake systems. One of the most popular ASE tests — and one where symptom-to-cause reasoning is everything.
When manually bleeding a brake system, which is the generally recommended practice?

ASE does not publish one universal passing percentage; the passing standard is set by test. TorquePrep uses 80% as a conservative practice target, not as an official ASE cut score. The certificate is issued once ASE verifies your required work experience.
What the A5 test covers
The official task list for A5 Brakes breaks down into these content areas — the practice bank above draws from all of them:
- Hydraulic system — master cylinder, fluid, bleeding, and valves
- Drum brakes — self-adjusters, hardware, and machining limits
- Disc brakes — pads, rotors, calipers, runout, and thickness variation
- Power assist — vacuum booster tests and hydro-boost
- ABS, traction, and stability control — sensors, diagnosis, and service precautions
- Wheel bearings and related hardware
