Jake Brakes. GOTTA HATE 'EM.

I love my new house, but there's one thing that pisses me off: I moved sorta close to an intersection on a major interstate. The road noise is not loud. It's actually kinda a nice ambient sound.... But every morning, I am woken up by

BLULULULULULULULULULUUUUUU... Reen reeen reeeeeen! BLULULULULULULULULULULUUUUUUU..... Reen reen reeeeeeeeeeen! BLU LU LU LU LU....LU.....LU.

If you know what a jake brake is, you know EXACTLY what I'm talking about. If you don't, a jake brake is a wonderful device the big rigs (18 wheelers, whatever you want to call them) have. Basically, you know how you can downshift in a manual and let off the clutch to slow you down? You're letting the vacuum of the engine slow you. Well, These big diesels have a little extra in this department. same basic idea, except it's kinda "turbo-charged" in reverse. They modify the valve timing, creating high backpressure to use the engine compression to actually slow the pistons. --And it exhausts out the pipes basically unmuffled, and at a velocity that makes it pop VERY loudly with each puff.

And I've been told that they don't even slow the trucks down very much. --That basically the only reason most truckers use them is to show off how sweet their loud custom pipes are. --Kinda like how Harley riders get the loudest exhaust possible. These guys are blasting their jake brakes because, for some strange reason, they think it impresses people. How inconsiderate, as they can OBVIOUSLY see they are passing a residential area. Generally, they're pretty good about it at night, but once the sun comes up, I guess they figure it's fair game.

P.S.- The person who told me the real low-down on jake brakes is a trucker, from a family of truckers.

You got mad skillz!
 
Yeah, mad skillz 😉 but do you have a .wav? I can't quite get the idea of it.

Our new house is at a road intersection, and I don't think we'll be getting the jake brake action but it is noisier than I'd remembered, must've been a Sunday when I got my first impression.
 
Wow I've always been under the impression that they actually helped a decent amount. Either way I can see how that would get annoying very quickly. Time to shut the windows and turn on the climate control 😉
 
HHAHAHAH perfect impression.
Well I never knew that about a semi.
What other good trucker life style info ya got?
 
I'll try to find a .wav. If not, just try this: In the loudest, most hideous, scratchy, low, DMX voice you can muster, YELL out BLULULULULULULULULULULUUUUUU. The "Reeeen reeeen reeeeeeeen" is those fsckers revving up to build more compression to get an even louder burst the second and third times (just in case it didn't CRACK my window the first time). --SO make it in a high-pitched turbo sounding voice.

Before I bought my house, I was in an apartment that was right next to a cloverleaf on the two busiest roads in town. All night, I'd hear jake braking. It's enough to drive you insane after a while.

A couple years ago the city started enforcing noise ordinances specifically aimed at jake braking.
 
Hmmmm....

Sure that's a jake brake? It KINDA sounds like one. But it sounds a little more like a loud passenger truck slowing down by downshifting. Who knows. At any rate, it's better than nothing, but it doesn't capture the essence. I have access to a really nice handheld DAT here at work and some nice mics. Maybe I'll go sometime soon and sit by the highway and see if I can get some sound bytes....

DesignDawg - yeah, I know what you're talking about, that one is pretty mellow (couldn't find anything better)...like I said, turn up your speakers really loud so you get the whole echo/resonance thing going on 😀😉😛. The bad ones are much higher pitched and make a distinct "pop"...
 
I drove truck for about 4 years, and the loudest brakes are the guys that run straight pipes. The newer trucks jakes are really actually quiet compared to the wanna be cool truckers with the big pipes. I do totally understand what you are talking about. Try sleeping in your truck in the desert, and all the sudden you jump out of bed thinking somebody just hit you, and it turns out dude is pulling up next to ya to crash out too.:disgust:
 
I don't drive truck for a living but I do work with a friend who owns a trucking company and drive em around all the time to take em in for maintenance and whatnot. There are actually two different methods used. some trucks have one or the other and some have both. Having both gives the greatest effect. He has both in his '98 Volvo 770 and it does work pretty good. You couldn't use it to come to a stop really. I'm pretty sure its intention is for use on hills or just highways to save brake pad wear. He has a couple other volvo daycabs that when ya switch it on it dont really do much. That wav file is the geniune sound of a jake also.
 
I know EXACTLY what you mean. I once had a house at an intersection and I sold it after about one year for that reason and I can't stand those idiots with the subwoofers!😀 Don't they realize it does not accent the music at all?!?!?
 
aaaah that is why I like living in an area very close to downtown full of college students and old people. It's almost like a small town here, very little traffic and the nearest freeway is at a good distance. Still I'm living maybe 800 meters from central Gothenburg, some 600,000 living here.

Mmmmmm like it
