Semi-Truck Brake Repair United States | 24/7 Roadside Assistance

In the world of heavy-duty trucking, your engine gets you moving, but your brakes keep you alive. There is no feeling more serious for a driver than stepping on the service brake pedal and feeling a lack of response, or hearing the hiss of an air leak that will not stop.

A brake failure is not just a mechanical setback; it is a life-threatening emergency for you and everyone else on the road. In the eyes of a DOT inspector, a brake violation can also mean an immediate out-of-service order that damages your schedule, your CSA score, and your revenue.

At MTS Truck Repair, we specialize in professional nationwide semi-truck brake repair. We do not expect you to limp a dangerous vehicle to a shop. We bring a fully equipped mobile brake unit directly to your location — whether you are stuck at a weigh station, parked on the shoulder, or sitting at a truck stop.

Are your brakes dragging? Is your air pressure dropping? Call MTS Truck Repair right now at 1-844-888-7587 for immediate roadside brake assistance.

24/7 Emergency Semi-Truck Brake Repair

Brake issues rarely happen at a convenient time. They often appear during a pre-trip inspection, after a hard braking event, in freezing weather, or during a roadside inspection. MTS Truck Repair provides 24/7 emergency brake support because a truck with compromised brakes cannot wait for business hours.

If you are red-tagged at a weigh station or unable to build air pressure at a rest area, you need a technician who understands the urgency. Our dispatch team works to get a mobile brake specialist to your location quickly and safely.

Safety is non-negotiable. If your brakes are failing, call 1-844-888-7587 now.

What We Fix: Air Brake & Mechanical Brake Service

A semi-truck braking system is a complex network of air compressors, valves, air lines, chambers, slack adjusters, drums, shoes, and ABS components. A failure in one part of the system can compromise the entire rig.

1. Air System Diagnostics & Leak Repair

• Air Line & Glad Hand Repair: We replace dry-rotted or damaged air lines and leaking glad hand seals.
• Brake Chamber Replacement: We replace damaged T30/30 chambers and other common commercial brake chambers.
• Air Dryer & Governor Service: If the system will not build pressure or the purge valve is stuck open, we troubleshoot the cause.
• Brake Valves: We help with faulty foot valves, relay valves, and tractor protection valve problems.

2. Mechanical Brake Components

• S-Cam & Bushing Repair: Sticking S-cams and worn bushings can stop brakes from applying or releasing correctly.
• Slack Adjusters: We diagnose and replace faulty automatic slack adjusters.
• Brake Shoes & Drums: For serious metal-on-metal conditions, we can help restore safe braking ability.
• Brake Adjustments: We check pushrod travel and adjustment issues that may lead to DOT violations.

3. Frozen & Seized Brakes

In cold weather, moisture in the air system can freeze and brake shoes can seize to the drums. We use safe methods to thaw frozen air lines and release seized brakes without damaging components.

4. ABS Diagnostics

• ABS sensor troubleshooting
• ABS wiring repair
• ABS modulator valve diagnosis
• Amber ABS light support
