Downhill In Snow/ice/slick Roads

Jake Brake off. ......... The higher the RPMs, the more effective the engine braking will be, just don't get into the over-reving zone (2000 RPMs and above).

Since Jake brakes and engine braking both affect the drives only, why is the latter recommended, while the former is an absolute no-no?

Jake brake is an engine brake. It's short for "The Jacobs Engine Brake," which is a registered trademark.

Wrong again.

The company lost its trademark rights due to genericde.

If in inclement conditions, no Jake brake.

If dry pavement, utilize this feature, but watch the RPMs.

These are great, thanks. I was concerned over being and to slow on a grade and this clears it up.

Good advice on the Jake/rpm relationship as well. In dry weather, I use the hell out of the Jake more so than the service brake. I should mention that I intend to buy this T680 from my company when they sell it. Does the Jake really cause a lot of wear and tear on the engine?

Appreciate all your responses!

Thanks for the information.

Timely topic. Thanks for posting. I was thinking about this the other day.

It doesn’t cause any wear and tear at all. The harnesses controlling the system do wear out and have to be replaced but it’s not an incredibly major repair. I’d advise strongly against buying that truck. Most companies keep trucks right up to the point where the power train warranty runs out and the reality is that modern trucks aren’t built to last. They’re built to pass along to the next sucker willing to land in a money pit.

Another thing you can do is disable the e-coast option on the freightliner automatics.

Something the carriers are not going to allow on their vehicles. "Tampering with a company vehicle electronics, wiring, engine, drivetrain, ELD, camera systems, etc." is going to be a likely termination. I've signed several documents during company orientations that detailed this fact.

A driver who worked out of the same terminal as I got terminated for just that sort of thing. He tried disabling the driver cam in the truck and tried hooking a laptop up to the diagnostic connection for the truck. It was speculated around the terminal that he wanted to try to remove the speed governor electronically. I have no idea if the governors are electronic or mechanical. Makes no difference to me because I am not pulling wny stupid moves like that.

Don't mess with anything on a company truck. They will know pretty quickly that something has been altered, usually before having to inspect it. Company shops can remotely check some of the information on how a truck is running. For example, they can remotely see the soot level of any truck in the company's fleet.

There is a setting tab in the dash menu that allows the operator to disable the e-coast. It's under setting and Auto defaults to on when the truck is turned off. Just like there are settings to adjust the cruise control, all are operator level options for many of the trucks functions. Even my company recomends that divers in adverser conditions to disable the e-coast so the truck stays under engine control
