I have a BD exhaust brake on my 2004 LLY Cheve diesel. Been on since 2007.It is great. However, it does not seen to work as well as it used to. Do this brakes ever need to be recalibtated? If so, ...
Mine was installed in 1996 on a 3126 Cat in a FL60. The toggle on/off switch has never been "off". I did have to replace the solenoid about 7 years ago.
