Newmar motorhomes are synonymous with luxury, residential quality, and exceptional craftsmanship, from the opulent King Aire to the popular gas-powered Bay Star. While famous for their diesel pusher and gas Class A coaches, their lineup has also included powerful Super C models. These high-end RVs are built on premier chassis from Spartan, Freightliner, and Ford. At Brisbon Automotive, we provide the comprehensive, expert-level chassis repair and maintenance your Newmar deserves. From full air brake service and Cummins diesel engine diagnostics to precision alignments on our heavy-duty rack, our skilled technicians in North Raleigh have the expertise to service your Newmar’s chassis and protect your investment.

Brisbon Automotive provides specialized repair and maintenance services focused exclusively on the automotive chassis utilized by Newmar’s luxury motorhomes.

Available Services and Repairs for Newmar Motorhomes
Your Newmar coach is a high-end investment built on a heavy-duty chassis from manufacturers like Spartan, Freightliner, and Ford. It requires a service facility with the tools and expertise to match. We provide comprehensive chassis service for your specific platform, from a 45-foot diesel pusher to a gas-powered Class A.
Preventative Maintenance
The preventative care for a luxury diesel pusher is extensive. We follow the chassis-specific schedules for your Spartan, Freightliner, or Ford F-53 platform. This includes complete oil and filter services for Cummins diesel engines or Ford V8s, fuel-water separator replacement, Allison transmission fluid checks, and full chassis lubrication.
Brake System Repairs
Nearly all Newmar diesel coaches and Super C models use full air brake systems. Our technicians are experts in servicing these systems, including air dryer cartridge replacement, S-cam brake inspection and adjustment, and diagnosing air leaks. We also service the heavy-duty hydraulic disc brakes on all gas-powered models.
Engine and Transmission Services
This is our specialty. We are your dealership alternative for Cummins engine diagnostics and Allison transmission service. We handle all “Check Engine” light diagnostics, fuel system repairs, and mechanical service for your diesel pusher, as well as full diagnostics and repair for the Ford V8 powertrains in the gas model lineup.
Suspension and Steering System Maintenance
Newmar’s smooth ride is often thanks to its sophisticated air suspension and Comfort Drive steering, often with an independent front suspension (IFS). We service all air ride components, including ride height valves and airbags. Our heavy-duty alignment rack provides precise alignments for these advanced coaches to ensure a stable, fatigue-free drive.
Cooling System Maintenance
Diesel pushers and Super C models feature large side- or rear-mounted radiators. We service this entire heavy-duty cooling system, including inspecting the hydraulic fan drive systems, cleaning the radiator and charge air cooler (CAC) stack, and replacing any belts, hoses, or water pumps to prevent overheating.
Electrical System Diagnostics and Repairs
The 12-volt chassis electrical system in a Newmar is highly complex. We diagnose and repair all driving-related systems, including starters, alternators, chassis batteries, and the multiplex wiring that controls your dash and lighting.
Note: We do not service the 120V “house” electrical system.
Exhaust System Repairs
We service the complete exhaust system, from the turbocharger to the tailpipe. This includes repairing leaks and servicing the engine’s exhaust brake (Jake brake). We also handle all maintenance and repair of the diesel aftertreatment system (DPF/SCR) to keep you emissions-compliant.
Tire Services
The tires on a 45-foot coach are your most critical safety component. We inspect all tires (including inner duals) for proper wear, age-related cracking (date codes), and inflation. Our heavy-duty equipment is designed to balance, rotate, and replace the large 22.5-inch (or larger) tires your Newmar requires.
DEF System Maintenance (for Diesel Engines)
A functional Diesel Exhaust Fluid (DEF) system is critical for all modern diesel coaches. We provide full diagnostics for DEF system faults, “limp mode” conditions, and warning lights. We service DEF pumps, heaters, and sensors to ensure your Cummins engine runs at full power.
