Burban ~ gonna split this so we don't Hijack the other guys thread :D



Anyhow....Do I love my Jake yes I do.

Back in June we were driving cross country.  Had a 99 Escort on a tow dolly.  Had pulled the front drive shaft so we were in permanent 2 wheel drive.  Coming through Oregon we hit 6" of snow (yes I said JUNE).  Ever few feet there was a car or truck off in the ditch.  We were very limited on options and had to just slow it down and make it up.  Every time the brakes were actually touched the back of the truck would try to slide out from under the dolly.  But with the Jake on the truck stayed under control and just moved down the pass.

I use it to warm the truck up in the morning.  Use to to keep off the actual brakes.  It's tied into the tranny control so it is like having tow/haul with OD when it is on.

I think it's BigRiver that has the PacBrake.  He speaks highly of his also.

the jakes are actuated by air pressure too arent they?  Do you have a air tank to go with the compressor?

Yup...........I dig the Pac-Brake on my ride. I leave it on 24/7. I tow occasionally, 5'ver, horse trailer, 20' boat and a 20' utility trailer.

I had it installed at a Campers World for a few years ago around $1400.00 if I remember correctly.

Like Jo mentioned, if anything, it really saves the brake shoes quite a bit of wear.

OK I don't have any great pictures of just the Jake...but you can see it behind the turbo



Here you can see it from under the truck where it feeds into the 5" exhaust



As soon as the site uploads I'll have a sound clip for you

Remember the difference in the equipment though. A Semi Jake Brake opens the exhaust valve during the compression stroke.  It is an integral part of the engine.  It works by re-routing the compressed air in the cylinders through the exhaust system.

My exhaust brake works after the engine.  Just creating back pressure that slow the movement of the engine.

I don't think even our Cummin's are stout enough to handle the pressures created by a full Jake Brake. I watched a clip once where a guy said it would blow the head off a 5.9 (he was from Jacobs and it was on Trucks or something).

It would be cool but Jacobs and Cummin work very closely if there was a way to do it (and a need) they would have done it already. 

You're welcome Burban.  I love the look I get from ricers when the truck is cold and I have it on stopped at a light.  The brake will kick in when ever the truck is stopped and not up to full operating temps.  I go from sitting :quote: quietly :quote: at a light to making all sorts of noise at them :lol: windows always roll up and cars tend to move.  I had one guy ask me once why I was boosting my turbo at a stop light.  After a little chat he went from thinking I was a nut trying to blow up my truck to understanding the value of the equipment.

Oh yeah and one thing to remember.

A state may not require a muffler on a diesel vehicle for emission reasons.  But more than a few have added legislation that requires them for vehicles with exhaust braking systems.  Most of them are written in regard to commercial vehicles only so we can normally sneak around them.  But it might be worth checking into before dropping the coin only to find yourself on the wrong side of the poo-poo.
