Everything You Need to Know About Brake Inspections, Maintenance, and DOT Compliance
Why Fleet Brake Maintenance Is Non-Negotiable
Your fleet’s brakes are the most important safety system on the road—and they take a serious beating every day.
- A fully loaded truck takes 20% longer to stop than a passenger vehicle.
- Brake failure is a leading cause of commercial truck accidents.
- DOT roadside inspections frequently flag brake issues, resulting in costly fines.
But here’s the problem: brake wear happens gradually. Many fleet managers don’t realize there’s an issue until it’s too late—until a driver reports trouble stopping, or worse, a truck fails to stop altogether.
At BFS Fleet Service, we specialize in comprehensive brake inspections and repairs to keep your fleet safe, DOT-compliant, and on the road.

1. The Top Causes of Fleet Brake Failure
- Air Brake System Leaks – Small leaks in your air brake system reduce stopping power over time. DOT inspectors check for these during roadside inspections, and too much leakage can put your truck out of service.
- Worn Brake Pads & Rotors – If brake pads wear too thin, they start grinding against the rotor—causing expensive damage and loss of braking power.
- Overheated Brakes – Repeated heavy braking leads to brake fade, where brakes become less responsive over time. This is especially dangerous on long downhill routes.
- Faulty ABS Systems – A failing Anti-Lock Braking System (ABS) prevents proper brake modulation, increasing the risk of skidding and jackknifing in wet or icy conditions.
- Corrosion from Road Salt – Rust eats away at brake lines, calipers, and drums—compromising your entire braking system.
Ignoring any of these issues doesn’t just put your trucks and drivers at risk—it also opens you up to massive liability.

2. How Often Should You Inspect Fleet Brakes?
The best fleets don’t wait for brake failure—they prevent it.
- Daily Driver Inspections: Drivers should check for low air pressure warnings, excessive slack adjuster movement, and unusual noises.
- Monthly Brake Checks: Inspect for uneven wear, air leaks, and fluid levels.
- Quarterly Comprehensive Inspections: Full diagnostics, rotor wear measurements, and brake line corrosion checks.
- DOT Compliance Inspections: Required at least once per year—but smart fleets do them every six months to avoid surprise violations.
At BFS Fleet Service, we offer comprehensive brake inspections and maintenance schedules that keep your trucks compliant, safe, and running longer.

3. DOT Brake Compliance: What Fleet Managers Need to Know
DOT inspectors love checking brakes—because it’s one of the top causes of out-of-service violations.
The most common violations include:
- Excessive brake stroke (indicating worn-out brakes or poor adjustment)
- Air system leaks (leading to reduced braking power)
- Brake lining contamination (from oil or grease leaks)
- ABS system failures (increasing accident risk in wet conditions)
If your truck fails a brake inspection, it’s not just a fine—it’s off the road until repairs are made.
At BFS Fleet Service, we help fleets pass DOT inspections with confidence by ensuring brakes are always compliant and in top working condition.

4. Signs Your Fleet Brakes Need Immediate Attention
Don’t wait for a DOT violation or a roadside breakdown—if your drivers report any of these red flags, it’s time for an inspection:
- Soft or spongy brake pedal feel
- Vibrations or shaking while braking
- Grinding or squealing noises
- Excessive stopping distances
- Dash warning lights (ABS, brake pressure loss)
Ignoring these warning signs can lead to major repairs, lost time, and accidents—all of which cost far more than routine maintenance.
