[Pat@BD]

Perspiring minds want to know. We need one for our 2004. 5.

They are available now. Give us a call.

jelag since you are a pacbrake dealer can you clue me into a problem I've had. I have installed about 6 packbrakes onto 01 and 02 dodges all have had problems with the vaccumm operated selinoid valve, some trucks have gone through two. I have had all of these failures in a short amount of time ( most less than 15000 miles ) I have discontinued to sell their products as I deemed the failures unacceptable, especialy when pac brake would not replace the defective valves. They would only fax me their service bulletion about cleaning the valve. Only one valve operated after cleaning, but then failed again in a two month time frame. I live in colorado where there is alot of interest in exhaust brakes, and have been scared to try any more because I had to go into my pocket to repair these deffects. To be fair I have installed a pac brake on an 04 that has had nothing but positive reesults. This customer live is the colorado mountains and tows heavily daily. We were going to spec a new 05 for our business and inquired about the dealer installed brake, and came here to find ut why it was dropped. Thanks to all for info through out this site. It comes in handy keeping our small fleet going ( the 97 is just about to turn over 300K can't wait)

DiscountDan - how many miles have you used that exhaust brake on your 04?

My Dad installed a PacBrake with upgraded valve springs on his new 1st gen. 5. 9L 235HP/Allison pusher in a 35' Vectra MH towing a Civic.



That was several years ago and he could drop off the Grapevine NB in CA at 45MPH without touching the footbrake. He never had any problems and this was an approved mod.



Now with my 3rd gen 325/600, 48RE I am more concerned about the trans than the engine.

Factory Exhaust Brake vs. PacBrake

Does the Pacbrake solve or prevent the issues Carlton Bale, Cummins Product Engineering, has been dealing with the Jacobs and the 48re?



Specifically the two major issues are:

(1) prevent the transmission from starving itself of lubrication when it keeps trying to achieve lockup. Maybe fixed by a software update

(2) the transmission needs the revised thrust washer. To load the thrust washer enough to cause wear, there needs to be an exhaust brake installed. Without a brake, there is no issue.



To me, an exhaust brake is an exhaust brake. They basically do the same thing and will have the same/similar problems, unless someone can explain to me otherwise.

 

[KYLE4]

I don't really wan't to get into the Debate but just so everyone knows the BD brake for the new cummins 600 went into production and will probably be available by the end of week

 

[drandre]

No debate here. I just want to know the differences and similarities of problems, issues, and advantages of the Pac Brake vs. the Jacobs. Basically, my question was whether I will have the same or similar problems as the Jacobs current status or are there fixes Pac Brake made to certify them with the Cummins 600. So is there anyone there that can answer my direct question?

 

[TCDiesel]

Look at the NEW PRXB By Pac Brake,It won"t solve the transmission issue"s. I Try one the other Day I was surprised at the braking power ,It was in a 8. 3 cummins. It should be available around the 1st. It has the bypass valve for consistent pressure,in a bolt on application and ATS command friendly. drandre at this time you will need add on equipment to get any exhaust brake to work correctly. Thier is now way without a commander of some type to let the brake know that the TC is Lock,and dis-engauge it when its not. 2005 may have the software But you will still need the hardware. I also see a engine brake in the future for the isb Which is far superior to a exhaust brake. The cost may be twice as much but the braking will be twice as good.

 

[LightmanE300]

DRandre you're screwed like the rest of us until you ugrade your trans $$$.

 

[RankRam]

LOL Yep that sums it up LightmanE300 !!!!

 

[simurdak]

I put a Pacbrake on my 2004. 5 and it works great with out a tc lock-up box. I needed a box on my 1998 and my 2001 but this truck stays is lock-up with out it. When in overdrive, it will drop out of lock-up at about 1500 rpm. With a touch of the throtle, it will lock again and hold untill about 20 mph. When the brake is on, it will lock out the overdrive until about 55 mph.

Jacobs brake now available

Finally a definite answer from Dodge. The 03-05 brake has been re-released by Dodge. You order the brake assembly and use the VIN to order the clamp on the turbo assembly, seems there are 2, based on build date. The clamp is non reuseable. A one use thing. Talked to Jacobs corp office and they flat out refused to sell me one. Called DC and they didn't know zip. Then complained to my parts manager and he called DC and finally got a response. He orginally had to send back 6 for credit when the hold was placed on last Spring.

I used a DB on my 95 and was very happy with the operation of it, and it was installed at a Dodge dealer at a TDR meet.

So, we shall see what happens.

[mgratner]

has it been approved for 48re or only stick?

[JWinans]

Only released and approved for the manuel transmissions

 

[SnoKing]

I'll add one other point to this discussion: It's also important to choose a manufacturer that will stand behind their product. Here's an excerpt from the PacBrake warranty (I'm surprised Jim didn't beat me to this):

Pacbrake Company will pay for all reasonable necessary repairs to

damaged engine components in which a Pacbrake retarder has

been properly installed, provided the damage is established to be

a direct result of a defect in the Pacbrake Exhaust Brake occurring

under normal use, service and approved application during the

warranty coverage. No engine damage coverage shall be provided

beyond this time period on replacement parts. ​

In other words, if a PacBrake floats the valves in your engine and destroys it during the two year PacBrake warranty period, PacBrake will fix it. That should be long enough to sort out any problems. I do realize there could be an issue of proof, but the intent seems clear.



Here's the corresponding text from the Jacobs warranty:

Mopar or Cummins will pay for all parts and labor needed to

repair damage to the Product or Cummins Engine due to a

Warrantable Failure. ​

Jacobs here seems to be relying on their status as the approved product to leverage the support of Dodge or Cummins. In 1998, Dodge was buying engines from Cummins without any warranty and thus was responsible for all engine failures (in exchange for which I'm sure they got a very good price). I suspect this is still the case and that it would be Dodge that would cover any failures.

I believe this is an issue with the 48RE transmission, not the engine. SNOKING

 

[brillmtb]

I was told by local dealer/mechanic that all you need to do on the 03 48RE is to keep the line pressure up with a BD type device and then the OD will stay on to lower speeds and you can then use a exhaust break.



I mentioned the ? bearing issue but he stated he has not seen any failure there but understands that they went to a needle bearing to better take the reverse torque.



He didnt feel the 48RE would suffer from an exhaust break if you did the above

 

[LightmanE300]

Brilltmtb - I believe it was the thrust washer, and the issue is enough lubrication and also software to keep the TC locked up when the EB is in use. We are screwed from multiple angles, lol



Answer this anyone who can - what aftermarket upgrades (from ats or dtt, or the like) are required to run an EB over the long haul? New VB and TC? The whole deal? Will that all still require a software upgrade, or will the trans commander or whatever controller they come with control the TC lockup for EB use?

New PacBrake PRXB

Just a cross-reference to a thread about the soon (?) to be available PRXB ebrakes from Pac here:

If the early reports are good, I think this is the one for me.
