Folks, I have 40K miles on this and the engine brake works just fine.

I down shift manually of course.

My toad brakes were not working thus adding an additional 5K lbs to the load.

I have not removed the rear drums yet for inspection. I did inspect them from the inside of the wheels of course.

This was a very very steep hill going into Death Valley from the East. I will post any findings when I get to them.

I know you're an experienced driver, was pretty surprised to read that you managed to smoke your brakes some how. Just trying to learn from your experience.

Looking back at that experience/in hindsight, would you slow further prior to descending next time?

I get how it might work, but was not aware they were using the turbo for engine braking. So I'm already up n that account alone!

not working fine enough.I have come down some pretty pretty steep mountain passes and @ 55 mph and with engine brake on I never even use the service brakes so just don't understand how u could smoke yours at 35mph

Some Cummins engines use the turbo in conjunction with the compression brake to add to the braking effect. My ISX is that way and it gives me over 600 hp braking force when set on high. I have yet to find a downgrade that required that setting.
Here's a link to the Cummins 2007 EPA ISX page": https://cumminsengines.com/showcase-...+2007#overview

But I certainly don't agree with this statement:

Your engine brake at 55 mph is significantly more effective than ANY exhaust brake at the same speed including the Variable Geometry Turbochargers. See Link. Or even my upgraded PRXB Pacbrake Exhaust Brake.

Apples and Bananas

However, I personally would not want a coach with a VGT if it is ALSO used as a brake. They seem to work great in diesel pickups and small trucks but not so great in large heavy buses and RV's.

For use in buses and heavy RV's the VGT should be used in conjunction with an engine brake.

Can't say I would do anything different. I have driven thousands of miles in 30+ years of owning RV's.. I had brakes go soft on a Class C and decided it was due to the wash board road working the brakes so hard that the fluid probably boiled.

Now I take it back. If I face that steep of a hill again I will crawl down it and stop in the road if I have too.

Your probably correct about the fluid boiling. There are charts showing how the age of brake fluid effects moisture in it. They also show the drop in boiling point, as the percentage of water goes up.

DOT 3*fluids*have a minimum dry boiling point of 401F (205C) minimum and a minimum wet boiling point of 284F (140C). It will be clear to amber in color and be hygroscopic (absorbs*moisture). It will absorb 1% to 2% of*moisture content*per year, depending on climate and operating conditions.

Did you buy this coach new?
Reason I ask; the previous owner of ours apparently didn't know how to drive it. When we bought it the brakes wouldn't stop very well and would smoke if you were in town just coming off of a highway. If I applied the parking brake and stepped on the throttle it would hesitate and drive away. I pull all wheels and found cracked, glazed and hot spotted drums from abuse.
I replaced the rear 7" wide shoes with 8.62" wide shoes, deeper drums with Fire Apparatus lining, the front got new drums and the same size shoes it came with but with Fire Apparatus lining also. No more smoke and WOW does it stop now. Before if I didn't use the engine brake it got scary trying to stop.

I am the original owner.

I would love to have more information on the changes you made. What parts and where do you get them for example.

The white smoke that poured out was so bad I popped a fire extinguisher under the axle for good measure.

you have a very serious brake issue for sure and best get it looked at
even without a proper brake assist at 35 MPH there is no way the brakes should acted like you discribe

Yeah, sorry about that.

I sure didn't mean to derail it. Who drives with the brake on is a bit wide open and hopefully the reasons why and why not helped.

Feel free to PM me if you want. I pulled the shoes and drums (one side front and rear)and took them to a truck parts house. Told them my problem and asked for a higher GVWR shoe. They called the wider rear shoes "Mountain Brakes". I asked if they carried lining spec'd for Emergency Vehicles, they did. They matched it all up (mounting points...shoe webbing) and out the door I went, cost me under $1000.00, went home and installed all of it.

OP wasn't really "wide open".... Was simple and straight forward - drive with/without engine brake; why/why not.... Calls for simple answers - no chasing rabbits or going off on tangents necessary...

Now takes me three times as long to find those that actually stuck to the original topic...
