Engine Brake on wet and rainy roads ?

Its dangerous. It could cause traction loss so yes, it is ill advised.

The guy that said it was OK should not have told you that as a trainee. It's one of those things people still do with experience but they may have some limits they use but don't mention in a quick conversation like how wet is it, how flat is the road, how much curve is too much. Whatever the case I'd suggest just slowing down before the hill so you don't need them.

Been driving for like 4months trainer hardly ever turned off engine brake. I use it if the roads are just wet and I'm heavy and the road is flat or straight. But I will NOT use it if there could even just possibly be ice on the road.
Using it on 1 when traction is good but road is damp should be fine. But dont go stage 3 on black ice and empty.

I use it , in all weather, but only in a straight line, I will learn real fast about the good ole law of physics when u Jake break around a corner to fast on Icey roads... On rainy roads I use my service breaks more often, they are not going to heat up much with water constantly being sprayed on them... Jake break is a tool , learn how to use it correctly ... Don't take a hammer to do a screw drivers job , same concept applies to trucking.. Learn how to use all the tools available to u , but always have a backup plan when stuff goes wrong, think about what ur gonna do if these wheels slide away from u , be proactive, it will save your life more than once , ask anybody that's been out here for more than a couple years

 

Lordy, unless you can mash the gas and spin the tires, your jake will NOT break loose. even on super steep icy hills it has to be very slick ice for your jake to break you lose unless you are also on the brakes, but it does happen. When it is real slick run your engine at lower speeds with the jakes on downhill grades, not much use to use them on flat ground. I run some serious grades and would be sol without jakes, wish I had a retarder to go along with the jakes.

 

I have had numerous times over the years living in Colorado that the jakes or retarder used on ice or snow pack that almost wrecked me. Had one truck older 3406B set up at 575 with Pac Brakes and Cat retarder
(pac brakes were better than Jacobs engine brakes on B models)With this setup you had to be cautious
you could actually slide the drives on a 7percent wet downgrade if you fully engaged both the jakes and
retarder at the same time. Would almost kill the engine if you didn't shut it off immediately. Having both was
fantastic doing heavy haul up here in the high country.

 

I'm a super trucker my Jake's stay on

 

Shouldn’t have any problem wet. But icy is another story.
The problem is braking your tractor. While no braking applied to your trailer. Your trailer can slide to the side.
Been told that when you apply your brakes. (Not jake). The system applies the trailer brakes slightly ahead of the tractor. This is for safety. To keep the trailer behind you.
