Description Make the Most of Your Power Stroke’s Heat Riser Valve! BD’s BrakeLoc connects to the engine heat riser valve’s control wire, turning the factory heat riser valve into an electronically-controlled exhaust brake. Automatic transmission-equipped models require the use of the BD AutoLoc computer to manage torque converter lock-up values for maximized retarding power. Please contact a BD technical sales representative for details relating to your specific application. Note that, because the heat riser is activated electronically, there is typically a 2-3 second delay between the time the valve is actuated and engine retarding occurs. While the BrakeLoc is an economical alternative to an exhaust brake, it is NOT intended as a substitute. For quicker, more effective braking, we recommend the vacuum-actuated BD Brake exhaust brake system, which utilizes our Variable Orifice Technology, and won’t stick like the stock heat riser can. NOTE: Valve show in picture is for reference only, not included.
