    I just love it when I hear a jake. It makes me feel like I am home cause everyone moves and I get a lane for myself and the truck besides me. Even on the east coast they them and the cops do not give a crap in this county.

    Gotta love those nice wakeup calls. A lot of jerks wake me up and with them and though it makes me mad, at least they know what they do.

    I was using that on a dump truck, someone had disconneted the Jake I reconnected it and found the reason soon, somehow you couldn´t switch it off so I just found my way of ####ing faster and floating.
    Talkabout lightning fast shifts on a daily basis :biggrin_25526:
    Then one guy stepped in for me and phoned whats wrong with the truck-- I told him nothing but he went on and disconnected it as he wasn´t up to shifting that way.
    If you weren´t paying attention the Jake could get you before you hit next gear and was on the gas again.

    What are Jake Brakes? same as "Engine Brake" on a Euro-truck? a valve in the exhaust closes, to give the engine braking force, to keep a slow speed downhill, without overheating the brakes?

    Engine brakes that realeases the engine pressures from the cylinders while not on the throttle.
    manufactured by Jacobs system.
    Found mostly on Caterpillar and Cummins (especially N14) on Europeans.
    MAN TGA engine brake is very similar in sound.

    Jakebrake uses the engines exhaust valves by opening them at the compression stroke.

    Godmorgen Mickey :)

    Ok, i drove a TG460A in Norway for about a year once.. just loved that "Tipmatic" gear, and how it could be used to brake the truck downhill :)
    I have an Merc Actros now, with semi-automatic gear.. its ok, but i liked the Tipmatic better..

    What are you driving?

    "Jake Brakes".. hmm.. them '..Mericans have the strangest words for some things.. haha

    Jacobs is a brand of engine brake. People tend to use it a a generic blanket term for all engine brakes. Kinda like xerox for a Photocopy

    Did you know that Peterbilt offers an in-pipe resonator for stacks up to 6 inches? It is about 18 inches long and just slides in the pipe. I bought one at springfield (MO) Pete for $118.

    How many sets of brake shoes do you get to replace a year? Truck and trailer? Oh wait.. its not your #### so hell.. burn em up. Forget that jake! I'll just stand on muh brakes till I see's some purty blue smoke rollin out the drums! Or do you have Jake envy? Don't have one, never used one, so you gotta bash on the guys that have and know how?
    I don't shift with the jake, but I do use it every chance I get slowing. That doesn't mean I'm rolling through a gated comunity at 2am hangin off the door with my head stuck in the pipe listening to it fart while one hand is down my pants doin the meatspin. I hope you're content with being a company man. Cause I don't see being a O/O in your future with that kind of thinking. Tell you what. In some areas, that would take about half a hour of "letting the motor naturally wind itself down" and "light" braking to get it even in low side. And that would be revving the crap outta it to even reach the next lowest gear. I bet you even grab that chicken stick just to slow down too. Forget it supertrucker. Just go on back to the Pilot and take somebodys hood off.
