the unnecessary usage of j-brakes, why????

You must have been napping in mechanic school. Jakes do no damage to an engine, if they did, why, oh why would they equip a brand new truck with them and put a warranty on it?

The action of a Jake actually scours the exhaust ports and removes soot. Properly used, they do no damage to an engine. It's the guys that think they sound great after a 2100 RPM engine is turning 2750 on a good downgrade that send parts flying.

Yeap, step on that treadle valve (I haven't heard that in 20 years), heat up those drums and hit the gravel bed. Good advice from the oil change pit.

Steering wheel holders and monkey wrench holders still thrive in this industry.

 

lol, Jake brakes do not damage engines, improper use (high rpm) does. People always find something to whine about, especially when group mentality takes over, i.e. yuppie groups that hear noises and try to initiate idiotic laws, either because of boredom or being city sheep. Sorry but sometimes jakes are necessary. Lucky you arent my neighbor, I have a pretty loud car that will shake your pictures. But if these new age whiners had anything to say, they would probably try to outlaw everything that makes noise near their house.

Dont get me wrong, some complaints are legitimate, but whining about trucks? Meh unless you re a truck driver you cannot judge or determine what is necessary use of engine brakes.

Dont forget who brings the goods to your local stores, and the stuff gets there usually by using equipment designed to do so, i.e trucks with an engine.

 

You know when I love to do it? When some moron in a 4-wheeler cuts me off and he has his window down or top down on his pretty little convertible thinking he is cool and funny when he cuts off 80,000 lbs of steel. I make sure to get my exhaust right next to his head and down shift a gear and let off the fuel. I do it to save my brakes also but it's also my nice little revenge against 4-wheelers that think they own our (tuckers) roads. They are lucky we let them use our roads Same thing with when my old truck used to billow out black smoke out of the exhaust (side exhaust I haul cars). Some kids thought it was funny to keep cutting me off and slowing me down well to make a long story short I happen to come up to my turn and they were going straight. I made sure m exhaust was perfectly lined up with their rolled down window in there p.o.s. rice burner. It made my day looking back and seeing them trying to fan the smoke and soot out of their honda civic with their doors.

You have to realize truckers do have our little "tricks" to get even with morons in cars. Just like when a cars refuse to let us over so we come on over anyways... its not that we don't see you.... it's more like quit being ignorant and get out of the way and share the road.

 

This is moronic behavior on YOUR part! While I agree that it can be ###### aggravating to have to deal with stupid behavior from 4 wheelers...To react by doing the things you claim that you do is a demonstration of your own immaturity and ignorance!

Drivers that do stupid crap like that are the primary contributors to our bad reputation and are the reason for the passage of stupid laws that we all have to deal with.

 

" They are lucky we let them use our roads "

Yeah ok , you seem to forget if it was not for THEM we would have very little to haul or need to be on OUR ROADS hauling it now would we.

 

Back then trucks used to hhave water on the brakes and lloads were llighter ttoo.

And I think Jake brakes were pretty well established in the early to mid 1960's, that's when my Dad got his. (Around the same time he switched from cheese blocks to stakes because there were no more one-log loads) Flatlander types were later to adapt.

That said, my first truck didn't have a jake & I hauled out of some pretty podunk places with it. And a 2-stroke Detroit doesn't have much hold-back, with or without a jake.

 

I didn't have water on the brakes (but since I was an O/O I did have Jakes) and as you well know the carrier that we both pulled for back then was hauling 80,000 pounds regularly even before the weight limit went up from 73,280 to 80,000...At least that's the way it was in the flatbed division.

 

That's called communicating your intentions and you don't have to ask their permission. lol

 

When I was buying N14's they Cummins dealer would set the top RPM<'s at 2300. When I asked why, he replied to let it Jake up to that point for better braking power.

I also know that the 600 HP Signature series produced 600 Braking Horsepower at 2100 RPM's.

The new ISX engines give you as much as the older style.

Personally, I think that Cummins has the best Jake of all.

 

On a pushrod motor (Pre- ISX) you don't want to run the RPM up much over 2100 with the Jake on because you can bend a pushrod pretty easily that way.
The old 2 stroke Detroits used to break rocker arms if you rev'd them too high with the Jakes on.
