Heavy-Duty Truck Brake Parts

Air brakes are the part of the truck you cannot afford to get wrong. JAK'S Diesel stocks a deep range of heavy-duty air brake system and compressor repair parts for Class 8 tractors, trailers, and vocational rigs — the gaskets, O-rings, valves, pistons, seals, springs, and repair kits that keep your air brake system sealed, building pressure, and stopping straight.

Most in-stock orders ship same-day, with free freight on orders over $1,000. Not sure a part fits your compressor or air system? We cross-reference OEM, competitor, and superseded numbers so you order the right part the first time. Call or text (720) 445-6249 to confirm fitment.

Choosing the Right Heavy-Duty Truck Brake Parts

Heavy-duty diesel components must be matched to the exact engine and application. Before ordering from this collection, verify the part number, engine model, engine serial number, and any casting or calibration number shown on the original component.

Fitment information to have ready

  • OEM, dealer, casting, or interchange part number
  • Engine manufacturer, model, and engine serial number (ESN)
  • Truck year and model when the component is chassis-specific
  • Core details for remanufactured or exchange components

Need a fitment check?

Use the OEM cross-reference tool or text a clear photo of the part tag to (720) 445-6249. A JAK'S Diesel specialist can confirm the match before the part ships.
