BD BrakeLoc
“Electronic” in this case, refers to simply
connecting to the engine heat riser valve’s control wire and
signaling to close the valve. A delay of 2-3 seconds occurs before
the valve closes and exhaust backpressure builds to retard the engine
revolutions vehicle speed. Automatic transmission equipped trucks
have this function combined with the BD AutoLoc or TorqLoc computer.
These trucks only require a basic wiring harness.
A stock automatic equipped Ford truck, prior to 1999, will disengage
the convertor clutch when the accelerator pedal returns to idle,
the brake pedal is touched or when the truck accelerates. Since
1999, the convertor clutch will remain engaged until the brake pedal
is touched. When the convertor clutch is not engaged the engine
free wheels and the engine rpm falls to idle with no transfer of
retarding horsepower being achieved.
BD’s BrakeLoc computer is designed to close the heat riser
valve on the Ford Powerstroke and will maintain convertor lock up
until a pre-selected vehicle speed. The BrakeLoc improves retarding
horsepower from 5 RHP, when the clutch is not engaged, to 200RHP
when engaged.
BD advises the driver that this “electronic” brake results
in a extreme amount of delay or distance before retarding occurs;
the amount of retarding force is 30% less than vacuum engaged BD
vacuum engaged brake and 10% of the stock Ford heat riser valves
that stick or bind. BD recommends, for instant and superior retarding
performance, the BD Vacuum Actuated, with a variable orifice butterfly
exhaust brake kit, be installed. It does cost more because of the
design and kit content but it is an engineered safer retarding device.
