Air Brake Inspection Steps for DOT Readiness
Air brake issues are one of the fastest ways to get placed out of service. A solid inspection process keeps your trucks compliant and your drivers safe.
Air brake inspection steps (field-ready)
- Build air pressure: confirm governor cut-out/cut-in is normal.
- Leak test: service + parking brake applied and released; listen and measure PSI drop.
- Brake application: confirm pedal feel and response.
- Slack adjusters / stroke: check stroke and adjuster function.
- Chambers and hoses: cracks, rubbing, dry rot, loose fittings.
- ABS lamp: verify lamp function on key-on and during operation.
What fleets should fix first
- Air leaks at glad hands, valves, and fittings
- Out-of-stroke brakes
- Cracked chambers and damaged air lines
