Brakes & ABS
Stop safely, every time.
Brakes & ABS covers hydraulic brake systems, disc and drum service, and modern ABS/traction control. Proves you can handle brake work from routine pad-and-rotor service through advanced ABS diagnosis. Everything below is free, no login, no paywall. Work through the skill areas, drill them in Study Mode, and when you're ready, prove it with the certification exam.
Your readiness to certify
Drill all 60 concepts in Study Mode. Mark each one "Got it" once you know it cold. When every concept is cleared, you're ready for the BRK exam.
What you'll be able to do
- Disc brake service: pads, rotors, calipers, hardware
- Drum brake service (increasingly rare but still critical for older vehicles)
- Hydraulic diagnosis: master cylinder, boosters, proportioning
- Brake fluid moisture testing and full system flush
- ABS module operation and diagnosis
- Wheel speed sensor diagnostics
- Electronic parking brake service
Skill areas
9 lessons, each one short enough to finish in a break. Every lesson teaches the system from the ground up, ends with a call to work, and tracks which concepts you have cleared.
Fundamentals
Everything else in brake work sits on top of hydraulic fundamentals.
Disc Brakes
Disc brakes are the bread and butter of shop work: a caliper squeezing pads against a rotor.
Drum Brakes
Drum brakes still ride on the rear of plenty of vehicles, and they behave differently enough from discs that techs raised on calipers get tripped up.
Hydraulics
The hydraulic side of the brake system — master cylinder, booster, lines, fluid, and bleed procedure.
ABS
ABS exists to keep the driver steering, not just stopping.
Parking Brakes
Parking brake systems have quietly become one of the easiest ways to damage a vehicle during a routine rear brake job.
Rotors
The rotor is the half of the friction couple everyone blames and few actually measure.
Pads
Pad selection and installation details determine whether a brake job is quiet and long-lived or noisy and back in your bay in six months.
Diagnostics
Brake diagnosis is pattern recognition backed by measurement.
