The BD Diesel 1027145 Brake system is designed for severe-duty applications, providing reliable engine braking performance for heavy trucks and fleet vehicles. This exhaust brake system features a rugged cast-iron housing and incorporates BD’s exclusive alumibronze bushing for maximum durability and leak-free operation. Controlled via a lighted On/Off toggle switch or an optional stick-mounted rocker switch, the system communicates with the engine’s electronic idle verification board for swift engagement, making it suitable for both manual and automatic transmissions. The design mounts either in place of the factory exhaust elbow between the turbo and the exhaust system or inline between the engine and muffler or particulate filter, ensuring compatibility across various vehicle configurations.
The system’s valve assembly is actuated by a high-strength air cylinder or vacuum cylinder, depending on the model, with the included air compressor capable of other auxiliary functions like air horns or air-ride components. It provides up to 150 retarding horsepower across the engine’s RPM range, significantly reducing brake wear during descending grades and heavy towing. Constructed with corrosion-resistant stainless steel mounting hardware and featuring BD’s innovative variable orifice technology, this exhaust brake ensures optimal control and thermal management under demanding conditions. The system also includes a monitoring port for retarding performance and an optional EGT port for additional diagnostics, making it a comprehensive solution for fleet and heavy-duty operators.
All components come with detailed instructions, and the system is backed by a 24-month or 24,000-mile warranty, emphasizing BD Diesel’s reputation for quality and durability in the industry. Whether used for everyday towing or severe fleet duty, this exhaust brake enhances safety, reduces brake fade, and extends the lifespan of your vehicle’s braking system, making it an essential upgrade for professional operators seeking dependable performance in demanding environments.
