Electric Exhaust Brake

[mattk50]

Ive got the US GEAR super duty de cellerater--been on now for 2 years. Works great and have not had any problems with it. i would definately do it again.

I prefer the Pac Brake (PXRB)for many reasons. One- you get a kit with it to pump up tires and etc. (mutli purpose- only on the third gen kits)Two- the pac brake will retard the truck all the way to 1000 rpms. Three- easy install Four-not in the way when installing a FASS or other fuel system( part of the jacobs brake is installed over the CP3). I have not dealt with the US gear brake, but I can tell you that an inline brake is not as easy to install as the turbo mount brake. Like mentioned before, the inline breaks will catch a whole lot more abuse being down near the frame rail.

My biggest reason for not going with the Jacobs was that you have to run a special serpintine belt on your truck so if it ever breaks I did not want to run the risk of not being able to find one versus the stock one being readily availiable.

You can re-fit the stock, shorter belt with no problems. You do have to bypass the vac pump, but I just did it the other day in a pinch.



The biggest reason should be better braking power and it is more sustainable at altitude, and the dang vac pump goes out on the Jake, and you can use the compressor for other things, especially if you add a storage tank.



Anyway, I too think the Pac brake is the ticket.

SS... What did you ever buy?

LOL!!!! Still haven't bought one. I will get one this winter def. Jacobs is out of the question. I have a Jake in my garage we pulled off of my friend's truck. He had it on for about one month until he caught the BUG and bought around $7,000 of performance parts. First part we put on wa his fuel pump and running the 1/2 inch line to the cp3 realized we could not connect it because the vacuum pump was in the way, out came the JAKE. Also you have to smash in your firewall to fit the elbow with the coffee can on it if u install an after market turbo, particularly the SS HTT 64/. So its between the US and Pac. Leaning towards the PAC since i want the train horns and air bags.



Thanks for your interest and sorry the response is so long.



Regards,



Sasha

The latest design of pacbrake allows the brake to hold the back pressure to a lower rpm... this is important for longer braking... .



When the brake is located a distance from the turbo and the brake comes on... the tube has to fill with pressure before the system works... .



Think of the exhaust pipe as the tank on a compressor... you need 60 psi for great exhaust braking... . if the space in the tube is 5 or 8 times larger then the space of the turbo mounted brake its going to take about 5 to 8 times longer to reach the magic 60 psi...



Why 60 psi... . any pressure above that on the cummins 5. 9 or 6. 7 would open an exhaust valve at the wrong time and there might be piston valve contact... . that's one reason why we suggest that unless you know your p's and q's you don't try to adjust the max pressure of an exhaust brake at home... BTW - each engine class has a different setting based on the engine builder... . as an example some Cat engines have such weak exhaust valves that exhaust brakes and engine brakes don't work well enought to warrent their expense... .



Both the Jacobs and Pac units have proven to surive well in the heat around the turbo... . Remember also that only Jacobs and Pac are approved by the engine builders for other engines and applications where they can be factory installed..... Cummins, Cat, Mercedes Benz, Hino, etc..... Also because of their programs with the engine builders they get direct contact to engine engineers where I can only assume BD, US Gear, and the others don't have access to... .



These are just a few of the compelling reasons to stay with the top names.....

Thanks Sasha. . no apologies necessary. Too funny though... I thought you would of had one by now. I had he US gear back in 2000 on an F350 and it sure made a bang when turning on and off. It would scare mechanics when they would work on it as it would cycle when you started the truck. It worked well but I don't think I would get another one. I want the stock one for my 06 even though there are vacuum pump issues. I don't want chrysler voiding my extended warratny for an aftermarket brake even though I think they can't. I only do the Smarty Jr so now problems of interference. Was your pull off for an 06? If it is and you want to sell, shoot me a PM. Thanks

I have a Jake and would not even thank of any other brake. I have not had any trouble out of my JAKE it is on a 03 stick shift put it on at 100 miles. Had to waite till the Dodge dealer got it in. I will not be with one--BEN
