The exhaust brake on my truck suddenly stopped working, the fuse is ok, where to from here please? Also, does the air dryer have anything to do with exhaust brakes? as I don’t believe this has ever been changed.
Not too familiar with this vehicle nor do I have adequate access to any repair manual information that might help assist in the next step. I will however go ahead and post this so that if someone else has some good information on your issue they might see it and reply.
