Descending grades with trailers can be hazardous and challenging, often resulting in overheated service and trailer brakes, which lead to brake fade, excessive wear, and costly repairs. The BD Diesel 1027145AP exhaust brake offers proven performance with its variable regulating back-pressure technology, providing reliable retarding power to enhance safety during heavy downhill operation. Controlled via a lighted toggle or optional stick-mounted rocker switch, this brake integrates seamlessly with the vehicle’s electronic systems, engaging quickly and efficiently when needed. Most applications feature BD’s turbo-mount design, replacing the factory elbow between the turbo and exhaust, or an inline configuration that mounts within the exhaust system between the engine and the muffler or DPF. Its rugged cast-iron housing incorporates BD’s exclusive Alumibronze bushing and a positive sealing piston ring, ensuring long-lasting, leak-free operation without blind holes where carbon or rust can accumulate. The brake is actuated by a durable air cylinder—either a new model with an air compressor or an earlier version with a vacuum cylinder—making it versatile for various engine setups. The included air compressor can serve multiple applications, such as air horns, air bags, or air-ride fifth-wheel hitches, adding to its utility. For trucks equipped with automatic transmissions prior to 2006, BD offers programmable AutoLoc and PressureLoc kits, which electronically control torque converter clutch engagement, reducing slippage and lowering transmission temperatures for optimal performance. All BD Brake kits come complete with the brake assembly, mounting hardware, performance monitoring port, comprehensive instructions, and most models include an EGT port for exhaust gas temperature monitoring. Designed for heavy-duty fleet use, this exhaust brake delivers up to 150 retarding horsepower across the engine’s RPM range, ensuring reliable control and safety on steep descents. Its corrosion-resistant stainless steel mounting hardware and rugged construction make it suitable for demanding diesel applications, standing up to high heat and harsh conditions. With BD’s exclusive variable orifice technology, spring-loaded cylinder pressure regulation, and solid offset butterfly design, this brake provides consistent, high-performance retarding power and long-term durability for commercial trucking and heavy-duty towing operations.
