The Jacob's Brake can be left on all of the time or turned on as required (old school style). It operates in a 'no fuel position'…. driver's foot OFF the fuel pedal. To activate, the driver takes his foot OFF the fuel (when the jake is left on at all times).

What are the cons about Jake brakes?

While both types of brake systems have their pros and cons, one of the main oppositions to the Jake Brake system is that it is known to be very loud.

Does idling in neutral save gas?

Most fuel-injected cars turn the fuel delivery completely off when you lift your foot from the accelerator. They still burn fuel when idling in Neutral, so do the math. The amount of fuel burned at idle over, say, a couple of miles of coasting downhill is small, but it's still more than zero.

Why do diesels need Jake Brakes?

"Jake Brake", or "compression release brake", is a component installed on diesel engines that slows the vehicle without the driver having to apply the service (foot) brakes. The Jake Brake releases compressed air from the cylinder, slowing the vehicle by absorbing the engine's power.

How does a Jake Brake work on a diesel?

The Jacobs Engine Brake® (also known as the "Jake Brake®") is a diesel engine retarder that uses the engine to aid in slowing and controlling the vehicle. When activated, the engine brake alters the operation of the engine's exhaust valves so that the engine works as a power-absorbing air compressor.

Should I use my Jake Brake in the snow?

Drivers, DO NOT use the Jake brake on icy or slick roads. It is not designed to be used in slippery conditions. If you do decide to use the Jake brake in other winter conditions (like snow or slush) it's important to make sure the tractor trailer unit is lined up and straight before engaging the Jake brake.
