Brake Safety Week is live right now — Aug. 23 through Aug. 29 — and the difference between a clean inspection and a truck sitting on the shoulder is a 20-minute check you can walk your driver through over the phone tonight. Most independent dispatchers treat enforcement weeks as weather: something that happens to you. It isn’t. Brake violations are the most predictable out-of-service category in the entire inspection program, which means they are also the most preventable. This is the check to run, the numbers to know, and the protocol to keep running after Saturday.
- Run a focused drum and rotor walk, check for edge-through cracks, severe scoring, heat checking, and measure lining or pad thickness on every wheel.
- Treat out-of-service brake violations as costly: lost loads, broker confidence damage, and long-term CSA points that restrict freight access.
- Make brake checks routine: add drums stroke and ABS lamp to DVIR, keep local shop contacts, and quarterly review carrier brake history.
What Inspectors Are Actually Looking For This Week
The Commercial Vehicle Safety Alliance announced Aug. 23-29 as this year’s Brake Safety Week, a seven-day enforcement initiative across the U.S., Canada and Mexico. Certified inspectors run routine commercial vehicle inspections with brake systems as the emphasis, and any vehicle with a brake-related out-of-service violation gets pulled from the road until it is repaired.
The part that matters for your pre-trip coaching is the annual focus area. For 2026, CVSA has inspectors placing special emphasis on brake drums and air disc brake rotors, and collecting condition data on both. That is a narrower target than “check your brakes.” It tells you exactly where to send the flashlight.
The Drum-and-Rotor Check to Walk Your Driver Through Tonight
You are not a mechanic and you are not going to become one this week. What you can do is give the driver a short, specific script instead of a vague “look at your brakes.” The full roadside inspection covers air leaks, slack adjuster travel, lining and pad thickness, drums and rotors, ABS function and chamber hardware — and any one of those can trigger an out-of-service order, according to a Brake Safety Week preparation guide from Rush Truck Centers.
- Walk the drums for cracks. Ask the driver to look for any crack that runs to the open edge of the drum, and for heat checking or blue discoloration that says the drum has been cooked. External cracks that reach the edge are the classic out-of-service find.
- Check rotors for through-cracks and severe scoring. On air disc units, a crack that goes all the way through the friction surface is a defect. Surface heat checking is common; a through-crack is not.
- Measure lining and pad thickness. The federal thresholds live in 49 CFR 393.47. Have the driver confirm nothing is at or below the limit on any wheel — and remember a single defective brake can start the count toward a 20% out-of-service determination.
- Chalk-mark the pushrod stroke. Have the driver mark the pushrod at rest, make a full brake application at 90-100 psi, and confirm travel is inside the readjustment limit for that chamber size. Two or more out-of-adjustment brakes on the same vehicle is a common OOS path.
- Run the air loss test. Build to governor cutout, shut down, and time the pressure drop with the service brakes applied. Audible leaks at chambers, hoses or the gladhands go on the DVIR before the truck moves.
- Confirm the ABS lamp cycles and goes out. A malfunction lamp that stays lit is a violation the inspector sees before the driver rolls down the window.
Brake drum and rotor issues may affect a vehicle’s brake efficiency. Broken pieces of drums and rotors may become dislodged from the vehicle en route and damage other vehicles or result in injuries or fatalities to the motoring public.

What an Out-of-Service Brake Violation Costs Your Dispatch Board
Price the downside before you decide the check isn’t worth the time. Brake violations remain a leading cause of out-of-service orders at roadside, and an OOS truck is not just a repair bill. It is a missed appointment, a load you have to rebook at whatever the spot market will give you today, a broker who now has a service failure in your file, and points in the Vehicle Maintenance BASIC on the carrier’s CSA profile.
That last one is the part dispatchers underweight. Severity weights and time weights mean a bad inspection this week keeps affecting the carrier’s percentile for two years. Shippers and brokers who screen on CSA see it long after the repair invoice is paid. A carrier that quietly slides into the alert threshold starts losing access to the exact freight you built your book around.
Turn This Week Into a Standing Brake Protocol
Enforcement weeks are useful mainly as a forcing function. CVSA runs brake safety campaigns on a predictable annual rhythm, and the underlying inspection criteria do not change on Aug. 30. Build the routine now while the urgency is doing the work for you.
Three concrete moves. First, put a recurring brake line item on the DVIR review you already do — drums, stroke, ABS lamp — so it is a checkbox and not a memory test. Second, keep a shop contact in each of your two or three heaviest lanes so a defect found at 5 a.m. becomes a two-hour delay instead of a lost day. Third, pull the carrier’s inspection history from the FMCSA Safety Measurement System once a quarter and look at whether brake violations are a pattern or a one-off. A pattern is a maintenance-program conversation, not a driver conversation.
What to Do Before Saturday
For the rest of this week, do three things. Send every driver the six-item check above as a text they can work through in a parking lot, not a PDF they will never open. Build one extra hour of slack into any appointment that routes through a state with heavy roadside activity, because a Level I inspection during an emphasis week takes longer than a bypass. And if a driver reports a cracked drum or a dragging brake, hold the load and rebook it rather than gambling — a reschedule costs you a day, an out-of-service order costs you the day plus the CSA points plus the broker’s confidence.
CVSA will publish the aggregate results later this year. When it does, compare your carriers’ experience to the national brake-violation rate. If yours came through clean, the protocol works and you keep it. If one truck got caught, you now know exactly which component to put on a shorter service interval before next August.
