Descending grades with trailers can be hazardous and challenging, often leading to overheated service and trailer brakes, brake fade, excessive wear, and costly repairs. The BD Diesel Brake, part number 2033135, provides reliable engine retarding performance to help mitigate these issues. This exhaust brake utilizes a variable regulation back-pressure design, which is controlled by an on/off toggle switch or an optional stick-mounted rocker switch for manual transmissions. It communicates seamlessly with the engine’s electronic idle verification system to ensure quick and effective engagement, enhancing safety during downhill operation.
The brake assembly features a rugged cast-iron housing that incorporates BD’s exclusive AlumiBronze bushing and positive sealing piston ring, designed to prevent carbon and rust buildup, ensuring leak-free operation over time. The valve is actuated by a durable air cylinder—either a spring-loaded vacuum cylinder for earlier models or an air cylinder in newer kits, which can also serve other applications like air horns and air-ride systems. Most kits include an air compressor, providing additional versatility for auxiliary air-powered components.
This brake system is compatible with a range of Dodge trucks from 1989 through 1998, including models such as the D250 and D350. Its proven design delivers up to 150 retarding horsepower across the engine’s RPM range, making it a trusted choice for heavy-duty fleet and towing applications. All mounting hardware is crafted from corrosion-resistant stainless steel, ensuring longevity and durability in demanding environments. The system’s innovative features include BD’s exclusive variable orifice technology, a stainless steel butterfly shaft, and a solid offset butterfly, all housed in a rugged cast-iron casing. Additionally, the pressure regulation and piston ring seals contribute to consistent, maintenance-free operation.
Overall, the BD Diesel Brake offers industry-leading performance, durability, and ease of installation, making it an essential component for heavy-duty trucks that require reliable downhill braking to prevent brake fade and protect drivetrain components. Its proven design and high-quality materials ensure long-term reliability and safe operation in severe towing and steep grade conditions.
