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 thatusing the exhaust brake in bad weather can not be used...any help on the matter would help, not looking for a argument.ThanksBill

What makes you think that you shouldn't use an exhaust break in "bad weather" (whatever that may mean - hot / cold / wet / dry / ???)

"Bad weather" can be subjective. I wouldn't use my exhaust brake on icy roads, because letting off the throttle could cause the rig to skid when the exhaust brake engaged. But slightly wet roads, at reasonable speeds, is a different matter. YMMV

You don't want to use it in very slippery conditions, like snow. It can make the wheels break loose.

Thanks, ScottG that's all I needed to hear....again thanksBill

Use your judgement, when it's icy, don't use it but if it's -40, which is bad weather in 50 MPH winds you can.

From the Jacobs Exhaust Brakes Owners Manual:

"The Jacobs Exhaust Brake is a retarding device intended to help control vehicle speed. It is not a vehicle stopping device. On an uphill climb with the Jacobs Exhaust Brake ON, taking your foot off the accelerator will result in rapid vehicle slow down due to uphill grade and retarding power. Operation on wet, slick or icy roads is not recommended. Use the Jacobs Exhaust Brake ONLY when you have good, dry traction with the road. Before shutting off your engine, always turn your Jacobs Exhaust Brake dash switch OFF. Your Jacobs Exhaust Brake should also be turned off when the engine is left idling for an extended period of time (longer than 3 minutes).

Never operate the Jacobs Exhaust Brake on wet or icy road surfaces. Always be sure of your traction".
