I have a 36 ft. motorhome with exhaust brake and have been driving many years both m/h and truck and I can't find where it is said that using the exhaust brake in bad weather can not be used...any he...
Bill, I've drove diesels with exhaust brakes all my life (44-1/4 years), and I didn't use a exhaust brake when it was icy or snowy! What a exhaust brake, retarder or Jake Brake does is it turns your diesel engine into a compressor by closing the valves therefore creating back pressure, which slows down the vehicle. Good Question
