Brake & air system repairs

Service from the
wheel end to the air supply.

We work on commercial trucks and trailers. Tell us your equipment type and symptoms so we can discuss shop or mobile service availability.

Brake components

We inspect wear, damage, and related hardware before recommending replacement.

  • Brake shoes, linings, and drums
  • Disc brake pads, rotors, and calipers
  • Brake chambers and mounting brackets
  • Slack adjusters and foundation brake components

Air supply & controls

Air-system concerns need a diagnosis that follows the leak or pressure problem to its source.

  • Air leak detection and repair
  • Air lines, fittings, and glad hands
  • Air dryers, governors, and compressor concerns
  • Brake valves and parking brake operation

Diagnostics & maintenance

Address warning lights and recurring brake concerns as part of your maintenance plan.

  • ABS fault-code and electrical diagnostics
  • Sensor, wiring, and connector checks
  • Brake operation and component inspection
  • Truck and trailer maintenance support

Warning Signs Your Truck Needs Brake Service

Schedule an inspection if you notice:

  • Longer stopping distances
  • Pulling or uneven braking
  • Low-air warnings or slow pressure recovery
  • Frequent compressor cycling
  • Audible air leaks
  • Brake, ABS or traction-control warning lights
  • Vibration, noise or burning odors during braking
  • Uneven or accelerated component wear
Some symptoms may indicate an unsafe condition. If you are uncertain whether the vehicle can be operated safely, stop driving and arrange professional evaluation or towing.
What happens next

A clear path to your repair.

01 / Share the concern

Have the year, make, model, truck or trailer number, and any warning messages ready. Let us know if the problem occurs while parked, braking, or releasing the brakes.

02 / Review the findings

We evaluate the affected system and discuss the repair needs, parts, and next steps with you. A worn part may be only one part of the problem.

03 / Repair & check

After the approved work, we check the affected components and operation. Ask about adding brake inspections to your fleet maintenance schedule.

Common questions

Before you schedule.

Do you repair trailer brakes as well as truck brakes?

Yes. We service commercial truck and trailer brake systems. Share the trailer type, axle information if available, and the symptoms when you contact us.

Can an air leak be repaired at my location?

Some air-line, fitting, valve, or chamber jobs can be handled on site. Call first so we can assess access, the likely repair, parts needs, and mobile availability.

What information helps with an ABS warning light?

Send the vehicle details and fault codes if you have them. Tell us when the light appeared and whether there are other brake symptoms. A warning light alone does not identify which part needs replacement.

How much will a brake repair cost?

The cost depends on the equipment, the cause of the problem, parts, and labor. Contact us with your vehicle information and photos; an inspection may be needed before we can give a repair estimate.
