Jake brake not working on high.

Unlike the wheel brakes you have on your car, the Jacobs Engine Brake (TM) is a "compression release" engine brake used by large diesel trucks, especially on steep downgrades. To understand how it works, remember that a diesel engine has much higher compression than a gasoline engine, typically 15:1. The jake brake slightly opens the ...A Jake Brake changes the timing of the valve so that it doesn't open and the exhaust gas can't leave, so it gets compressed inside the chamber by the piston. It works like a spring essentially, the piston loses energy (meaning it moves slower, meaning the truck slows down) and the gas gains energy by being compressed.This is a video on performing a tune up on C12 engine.

the high and low switch produces the same amount of braking. The trans downshifts to 4th then stop downshifting. That cause me to use the brakes to slow the coach. This is my first coach with a jake. previuos coaches were Cat engines with exhaust brakes. I think they should act similar.??

These compression brakes hold pressure in the cylinder then releases it in an explosive, very noisy manner. That's why so many communities have ordinances against Jake Brakes. An exhaust brake, mounted just after the turbo, is usually a butterfly valve that is turned by a lever to partially block the exhaust gasses.

The spool valves can leak or blow apart causing a weak Jake or a cylinder to not work on the Jake. The spool valves also act as detents and park the Jake rocker arms when the Jake is not in use. If the spring gets weak the Jake rocker arms may not detent and if they don't then they will clatter back and forth and loose the oil trapped in them.

Yes, because in a Jake brake, you release the compressed air at the top of the compression stroke, and then close the exhaust, so you create a vacuum during the work stroke of the cycle. In a gas engine you get some braking from the compression, but it's not vented early, so the cilinder will basically decompress the high pressure to atmospheric.
