Exhaust brake in

[jelag]

Guys



There is a lot of hype out there about one brake being better than the next... ... . Some of the vendors are testing their products at different RPM to comfuse the issue... ... .



Part of what the brake does is basic physics... ... .



So if you have the same RPM and the same Back Pressure you should see the same results..... retarding HP This I know from watching the dyno's and talking to the engineers... ...



We're a PacBrake Dist, and their oldest one... ... . they we're the ones that started exhaust brake... ... . when we saw the need where we couldn't fit an engine brake to the engine..... You might visit the web sight, www.pacbrake.com for a good understanding of what happens.....



Look for features that will extend the life of the brake, like the "Nitrate" coating..... as the vendor for the Back Pressure, ask them if they have a port where you can test the back pressure..... and look for ease of installation for those of you wishing to install the brake yourself.....



If you have any questions please feel free to PM me or post them.....

Dean and others,

When I took delivery on my truck in November, I took the $299. 00 deal that was offered for people with a business. Had to have a tax & business liscence to qualify. I had the $299. 00 proce figured in with the deal I made at the time. I understand they raised the price after the fact, but my dealer said you expected to pay the $299. 00 price, so that is what you will pay, period!

I received the jacob's brake and installed it myself as I did not want it done by the dealer. It was not that hard to install, and the directions that came with the package was extremely good!

The brake works very well also.

Wayne, you got a heck of a deal on your brake. As I understand it that price was based on the cost of the pre '03 product (without the vacuum pump). I tried to get that price but couldn't and was told the "old" price. The part number changed and the price went way up. The dealer was just as upset as I was about it.



I almost cancelled my order, but having towed with the Jacobs brake since 1998, I really didn't want to leave home without it. I was more that satisfied with it's performance and never had a problem from day one. A couple of friends of mine have the '03 Jacobs brake and are impressed with it. I can't imagine Cummins putting their name on something that is not first rate. Cummins is the only reason I switched to Dodge in 1994.



As far as the compressor goes, I carry a small $40, 12v one in my toolbox. I think it would take a while to fill up my truck tires with that or the small compressor that would come with other ebrakes. I guess it all boils down to what you want and what you believe works best for you.

Hey everyone, brake is in truck where it belongs and works great !!!Oo. Oo. Be towing the racer up to So. Utah Saturday morning can't wait to see how it does!! Seems to be doing great on the truck empty though. Appears stealer did a O. K. job installing it too!! And NO they did not even try to get more $$$$ out of me for it either! $840- $500= $340 + installation =$645 total!!

for the guys who installed there brake switch,did you run the wire like the directions said or did any one sneak it between the boot and shift handle. looks like it could work and look cleaner. mike

 

[Casey Balvert]

It helps to warm up the boot but it does work and it does look cleaner.

That's where mine is going, too.

I removed the gearshift knob, then lifted the boot up til the opening was near the top of the shifter installed the wire cord between the boot opening and the shifter, then pulled the boot back into the original position and reinstalled the knob. This procedure made it real simple to get the cord between the shifter and the boot.



This makes it look much better than running the wire cord over the boot.

exhaust brake

I got my Pac Brake exhaust brake from Pacific Brake and Clutch in Spokane, Wa. and installed it myself, The install took me all of 4 1/2 hours. It is a fairly simple project,. but I must confess I retired as a Heavy Truck and Equipment Mechanic, so I had the needed tools for the job.

The Pac Brake comes complete with the air compressor and the Brake unit, It includes a toggle switch for a dash swith unless you prefer the gear shift mounted switch and I do believe that is an extra option, ( Depends on your dealer ) . The compressor that comes with the pac Brake is capable of pumping to 150 PSI preasure, so with the addition of a small air tank, a 1 way check valve between the compressor and the air tank, one can use the onboard compressor for airing tires, air horns and many other fun stuff things.

Ok, back to the brake, I have my 1993 12 valve cummins in my 93 Dodge and I installed the jacobs exhaust brake on that truck many years ago and was very satisfied with its performance. I am here to say that I am equally satisfied with the performance from my Pac Brake on my 2003 24 valve Dodge/Cummins.

Rich,



4 1/2 hours! I can't believe it took you so long -- the banner ad says it only takes 2 1/2 hours for an '03 PacBrake!



Seriously, that's about the same amount of time it took me to install the first 03 Jacobs/Cummins brake. I got it down to under 4 hours on the second one. Sounds like the installation times are fairly comparable for the two designs.



Enjoy your brake!

My Jacobs Exhaust Brake was installed yesterday by Bolles Motors in Union, CT. It was at the end of a long list of "gotta haves"for my truck. They did a very professional job of installing it and ran the switch cable through the boot as per my request. I can't imagine why in the world the instructions have the cable drapped over the boot, it makes it look like it was bought at a garage sale.



I didn't use the brake much yesterday because of the big storm we got here in the Northeast. I did try it out where I could with no traffic around and it seems to be just as good as the Jacobs brake on my 98. 5. I did notice that the brake seemed quieter than my old one and there is the sound of air coming out of the airbox when the brake is on that I never heard before. I have been told that this noise is from valve overlap.



I am really going to like the stalk switch. The old model had a rocker arrangement that I never really liked. The unit looks to be extremely well made as well it should be for the price. After spending as much as I have on this vehicle, I cannot complain about the cost of the brake. I have towed with one and without and I did not even entertain the idea of pulling my trailer without an exhaust brake, even thought the service brakes on the G3's are far superior to previous CTD's that I have owned.



One thing for anyone doing the install themselves. The existing exhaust elbow has a couple of small alignment dowels to match up with the turbo. The ebrake does not have the alignment dowels and care must be taken when lining up the brake and the turbo. The gasket there is pretty thin and looks like it might tear easily. I believe the material is graphite. I have been told that it is a good idea for the parts to be cold when putting them together.

I have been looking for an alterante power source for the exhaust brake relay rather than splicing into a wiring harness. Has anybody use the spare fuse 37 with an ad a circuit for the power?

 

[Rich Hoefer]

Blue Goat

I have used the spare # 37 fuse location, but not for the exhaust brake, I used that location for the key hot power source for the Battery isolater for my trailer charge circut. I cut down a spade connector so it would fit the hot side of that spare fuse holder, and then installed a inline fuse holder and run the wire out through a small groove i filed in the edge of the fuse box cover to my Isolater, works fine.
