Brake Controller and Jake Brake

Thread rating:  |
toowide - 10 Jul 2006 04:18 GMT I recently added a tow kit to a diesel pusher and am pulling a Honda CRV with a proportional braking system. I've read about (1) how to "calibrate" the brakes on a gravel road using the gain control, and (2) to make sure that I never back up without first disconnecting the towed vehicle. All that's the easy part.
What's more difficult for me is figuring out how to go down a long, steep grade where I always keep my speed down using the Jake brake. Seems like the towed vehicle is constantly going to try to charge into the back of the diesel pusher (just about the same as backing up with the tow still attached) unless I use the manual controller.
But how do the real experienced drivers figure how much to lean on the controller? Do I primarily look for sway, which I've been doing, or something else?
Thanks!
CoachPotato - 10 Jul 2006 05:11 GMT I drove many miles in big rigs with Jake brakes, and never felt the need to feather the brakes on the trailer(s). Don't know why you'd have to with your rig.

So when "the towed vehicle is going to try to charge into the back of the diesel pusher" it will automatically put the brakes on the correct amount so you won't even know it did it. You are worrying about nothing.

His question concerns the toad pushing the motor home down the hill when the MH Jake Brake is being used, not the service brakes. Not a bad question.
The answer is that if the Jake is not slowing the combination sufficiently, it is necessary to use the service brakes, which will activate the auxiliary braking system in the toad. We need to do that all the time, since ours has only an exhaust brake, not a Jake.

That's when I start using lower gears to slow the rig down. I've seen them that didn't make it using the brakes and a lot more close calls. If you ever see a rig go over the edge out of control with the wheels blazing from the brakes getting red hot, you'll think twice about relying on brakes to slow you down going down a mountain. The worst I ever saw was 2 18 wheelers not making a curve on I-68 in WV within 2 minutes of each other while I was creeping along at ~15 MPH in 3rd gear of my 12 speed rig.

As you know, the majority of drivers don't have a clue on how to drive in mountains, ESPECIALLY when driving a heavy rig. Many of those same people don't want to know & go haphazardly flying down the mountain grades. The poster most likely has never driven enough to see the slow truck lanes going both up and down mountain grades.

CoachPotato - 11 Jul 2006 01:32 GMT CoachPotato continues to snort...
Au contraire, experts. I have years of big rig driving experience, and much of it in the mountains. I drove logging trucks back in the 70s. Those were the old days with twin stick main and Brownie transmissions, selectable Jake brakes (2, 4 or 6 cyl) and uphill or downhill seemingly all day long. I hauled logs in those days from the Susanville and Chester areas to Red Bluff in Northern California. And I've hauled lumber and plywood to the LA area from mills in the north. I've also pulled tanks all over California, as well. I do have a clue about how to drive a loaded big rig through the mountains.
And I'm gonna tell ya that if you're going downhill on an interstate highway at 15 MPH in an RV or a big rig, or anything else, you're nuts. You're causing an unnecessary hazard to other vehicles - some of which weigh 40 tons and more.
You seldom see grades greater than 6% on the Interstate system. You may see 7% grades on state or US highways, but I don't recall any such interstates. And loaded to 80,000 lbs, the usual maximum big rig limit, you can go downhill on the Jake for miles and miles at 35 MPH without overheating the service brakes. I've done it hundreds of times. Didja ever go down "Five Mile" towards Bakersfield on the "Grapevine" with a backhaul of sheet rock? Maybe you should try it so you'd know something of what you speak. If you drove down "Five Mile" at 15 MPH you'd likely cause an accident.
For myself, slowing down for some fool doing 15 MPH downhill on an interstate is something I don't recall ever having to do. My hope is that you stay out of my way, Tom!
Third gear in a twelve speed transmission, eh,? Twelve speed? Well, I've never driven a twelve speed, don't even recall hearing of one, but third gear in the old 13 speed RoadRangers would likely be even less than 15 MPH.
Chatter on, "experts"...

I won't claim to know anything about this stuff. I have never driven a big rig. However, my question is: If you can't handle coming around the curve and finding a jerk in an rv doing 15 mph, what happens when you come around the curve and see a bicyclist doing 15 mph, a pedestrian doing 2 mph, or a disabled vehicle doing 0 mph?
> interstates. And loaded to 80,000 lbs, the usual maximum big rig limit, That reminds me, another burning eternal question I've had that the newsfroup can answer. Why are big rig tractors labelled "GVW 80,000 lbs", when the 80,000 number refers to what is described as GCW in light trucks? I had guessed that 80,000 was the GVW for the tractor alone, and the trailer's axles had to carry any weight beyond 80,000 (up to whatever the GCW is for the tractor, and obviously not exceeding the GVW of the trailer), but recent discussions here have led me to believe otherwise.

Because a light truck is designed to carry a load. A tractor is designed to pull a load. A light truck can have a load on it, plus pulling a load, hence the GCW. 80,000 GVW is the max legal weight without permits. That takes 5 axles to carry. 12 on the front, 32 each on the tandem drives and the tandem trailer.

Why are big rig tractors labelled "GVW 80,000 > lbs The tractors are not labeled GVW 80,000#. The 80,000# you read is the gross weight that can be on the wheels of an 18 wheel rig, IF it is loaded just right, and be legal to go down the interstate without an overload permit. That would mean you had to have exactly 12,000# on the steer tires and exactly 34,000# on the drives and the trailer tires. Most states will let you fudge a little as long as it's not over gross. The label of the tractors are Class 8.
Thousands of trucks roll down the interstates every day with permits that are way over the 80,000#. Unless they've changed the regulations in the past 12 years, MI allows some of those "mule trains" to run at 135,000# gross without a permit.

And add that yrs trly, though never a truck driver, was born at night but not last night and has seen MANY a heavy rig crawling up or down long steep grades.
Of course, I have also seen plenty of cowboys running heavy and fast with brakes smoking.
It is true that MOST interstate highways would permit faster speeds under good conditions - but with your vast (or is if half-vast?) experience you may have noticed that conditions are often NOT good. Such as fog, rain, and even s**w.
Bottom line: anyone who expects heavily loaded trucks to maintain 40-50 mph is sooner or later gonna have his expectations (or his rig) shattered.

Congrats, Will, that sure is a lot easier than investing years actually gaining experience doing such things.
First and foremost, a 6% grade in WV is the same 6% as we have here in California, except that we probably tax it here. 40 tons going downhill is subject to the same pyhsical laws everywhere. So whatever your point for that statement - it was pointless.
Secondly, you and Tom "have seen" all manner of things and think that makes you experts. By the foolish claims he makes and you defend, you neither one have a clue about driving big rigs, yet for some reason you jump into a discussion about jake brakes and downhill driving and wish to slam my differing view - even though I've had years of experience doing the very thing you admit to having never done.
You pick some pretty strange debates for someone born so many nights ago.
I'll say it again and if you want to continue your foolish arguement I'll be happy to oblige: Driving 15 MPH down an interstate highway, even downhill with a 40 ton truck, is a stupid thing to do. 15 MPH is dangerous on an interstate no matter what you've seen and no matter how many nights ago you were born. Big rigs loaded to 80 grand can go downhill with their Jake brakes at 35 MPH safely - for miles.
And now, out of the blue, it's 40-50 MPH that you wish to debate? This discussion is about 15 MPH on an interstate highway, Will. We can discuss higher speeds later. Perhaps I convinced you that 15 MPH is foolish? I hope so. Please share your epiphany with Tom.
Bottom line: You and Tom don't know what you're talking about, Will. You can't even stay on topic...

I note that you have abandoned the whole point of this debate: Tom's little sermon about the necessity to drive 15 MPH on interstate highways. 15 MPH is now 25-50 MPH in your latest posts. And Tom has to refer to tornados and extreme weather conditions to bolster his 15 MPH on the interstate nonsense. Y'all just don't know when to quit.
I am guilty of pointing out the error of Tom's foolish recommendation to drive 15 MPH on an interstate highway - and your defense of that nonsense. And that makes me the bad guy, eh? That my contrary - and correct - opinion was taken as an insult says it all. Oh, well...

The topic is using a jake brake when a toad is pushing too.
Perhaps the OP can connect a potentiometer in parallel with the manual control on the brake controller. I've considered that hack for my rig (but not for the same reasons).

(regular brakes or Jake brake) I think the OP has a common electric brake controller.
toowide - 13 Jul 2006 03:20 GMT Being the OP, I'll tell you that I have a 40+ foot diesel pusher with a US Gear unified tow brake for the toad. It engages the toad's brakes proportional to either the application of the air brakes or manual depression of what I call a "thumb switch" on the brake controller. So, if I hit the brakes coming off Chestnut Ridge on I-68 in WV (before trying the Evel Kneivel jump Cheat Lake trick), the toad also brakes... more or less with the same force.
But, if I rely heavily on the engine exhaust brake, as I have become accustomed to doing, the toad's brakes don't engage. So, what happens is that the toad is trying to shove the Blue Ox tow bar assembly through the rear end of the motorcoach for 5 miles.
Somewhere back up in the thread, I did get a response that pretty much said, "Don't worry about it unless you see something getting out of control on the rear monitor."
I'm just new to this set up and wanted to know what other similarly-situated folks do when they're making long descents.
>> >>The topic is using a Jake brake when a toad is pushing too.<< >> [quoted text clipped - 3 lines] > > I think the OP has a common electric brake controller. wwemu@cwnet.com - 13 Jul 2006 03:56 GMT I, too, have the same setup. I use the jake brake as much as possible without causing wear on either the service brakes or the toad brakes. If the speed increases to the point that I have set (in my mind) that is faster than I wish to go, I use the service brakes, which also engages the toad brakes, to bring the speed down to a point below my desired speed, allowing it to build again. If necessary, I will slow to the point that I can select a lower gear that will allow the Jake to handle it alone. As far as the tow bar being able to take it, if it won't, you need a different tow bar. I have used Both Duncan and Roadmaster for over 15 years with no difficulties. I have even backed the toad. It can be done if using care.

I have the USG system on my Winnebago/Ford. I tow a 4200lb 4Runner with it and when I gear down on a descent, the 4Runner doesn't cause me any problems. If I need to, I will use the brakes, which will activate the progressive feature of the system if I brake hard enough. If I don't have to brake hard enough for the decelerator to sense it, nothing happens and I don't worry about it. The 4Runner has receivers bolted to the frame for the toad part of the towbar, and the hitch is bolted to the MH frame, so neither will be damaged by the 4R pushing or being pulled. Your setup is probably the same, but with a lighter toad and a heaver MH. BTW, I have my gain set light so with light braking the MH handles it, but with heaver braking the gain kicks in. Ron

It isn't the way I *think* you drive, it's the way you say you drive!
You claim to drive 15 MPH on interstate highway downgrades and even the 6% grade below Bakersfield. Man, that's my old stomping grounds and I've *never* seen anyone drive that slowly there or anywhere else. I don't know why you claim to drive so foolishly right here in front of God and everyone. Strange. Any real truck driver that might join in would tell you the same.
Loaded trucks blown over on the grapevine, and you saw it happen? You've never seen a flatbed load blown over, I'd bet, and how can you tell a van or tank is empty? Come on! Get real.
And now you're taking that old motorcycle drivel about no old truck drivers, insinuating it's because they drive over 15 MPH down hills?! Truck drivers generally grow old, Tom. Only 905 died in 2005 on the job. That's a tiny minority. And I'd dare say most of those deaths were caused by sleep deprivation or four wheelers.
I gotta give you the benefit of the doubt, Tom, and blame these outrageous claims on medication or something. Nothing else makes sense.
I hope you do well. Let's continue this after you get back from a very successful surgery.

Typing single handed after bing cut on, but I can tell all of you that there are interstates that have grades a lot steeper than 6% (most in the East), Mount Eagle I-24 east bound in TN (MAXIUM truck speed if fully loaded 25 mph) and very few try it that fast, I-40 in eastern TN, same as as I-24 & the steepest grades of any, interstate I-68 in West Viginia that makes several back to back 90 degree turns on short radius at over 8% grade.
The last item I was rediculed on was 18 wheelers blowing over on the interstate. Four times have I seen this. One WAS downhill on the Grape Vine in CA where 8 trucks were blown over within minutes of each other, spliting open and spilling loads. One was between Tuscaloosa and Birmingham, AL on I-20 where a tornado picked a loaded truk up and scattered it for about 1/2 mile. One was on the bridge from Buffalo, NY to Ft. Erie Onterio where 2 18 wheelers being escorted by the highway partol at 15 MPH because of high winds overturned while on the bridge not moving. One was on I-194 just north of South Haven, MI where a furniture van was blown off the road by staright line winds coming off Lake Michigan. I was never there when it happened, but there have been enough 18 wheelers blown over on the Mackinaw bridge between Canada and upper MI, that they run escorts at 15 to 25 MPH many days of the year and the bridge can be completely shut down for hours at the time. I waited over 7 hours for them to open the bridge on 1 trip.
When you guys have driven 48 states and Canada 12 months a year in all weather conditions, Just maybe you'll get the message. If not, God help you!!

They were caught by 60-70 mph crosswinds during a thunderstorm yesterday afternoon. One of the drivers was quoted as saying something to the effect that he drove into a wall of water and then the wind just blew him off the road. Not terribly unusual for thunderstorms here which can have streight winds in excess of 100 mph and can snap utility poles.
