Pac Brake C44045

[NWroten]

I am very interested in adding a Pac-Brake, are there any others who have any feeedback on how they perform on an automatic equipped truck? Thanks, love the site.

HGreen,



How would the clutch switch prevent this though? It seems like even if you had the clutch swtich, the instant you'd let off the go pedal, the brake would activate still. Or would you have to install the shift-mounted switch to turn it off while you're accelerating, then back on while you're deccelerating? Would that fix the issue without the use of a clutch switch?? I figured $35 was a little steap for a simple shifter-mounted switch that I could go get from a semi tractor salvage yard, but I think those are mostly air switches, where the one with the pacbrake is probably electric (this is just my assumption, based on the fact that the pacbrake ties right in with our truck's complex electrical system).



NWroten,



I recommend contacting Jelag. He has been very helpful in answering my questions and offered me a price that only one other shop (which happens to be managed by a close friend) could beat (and only by 50 bucks). However, I will probably end up going with Jelag because of his customer service. The service from the other shop would be questionable. Jelag even offers free shipping!!!









My last question for members reading this post: Do you guys find exhaust brakes advantageous while you're running unloaded? The advantages of running one while towing is obvious, but I assume they are just as helpful for use when running empty? I have a 6 speed and figured it would require a lot of shifting to do this, but I heard from one member that he could come all the way down from 60 to 5 mph without ever touching his service brakes and do it in a reasonable distance.

Kait --- There is a already a slight delay, maybe 2 seconds, built into the ECM before the PacBrake is activated, but my shifts last longer than that, so the brake begins to activate. The switch just turns off the brake like the dash or shifter switch would, but you don't have to do anything. It drops the ground to the white wire, if I remember correctly.



The advantage when running empty, saves the brakes. Getting off the interstate tonight, it had me almost stopped before I reached the top of the ramp and I never touched the brake petal.

THANKS, HGreen for the heads up! Now I can't wait to get the PacBrake!! I am going to get the one that keeps the backpressure at a constant 60 psi irregardless of engine rpm. Hopefully it'll save my brakes some wear and tear!



Also, I think I'll install the shifter-mounted switch and just control it myself. I know everyone has their own likes/dislikes, but I don't mind having to switch it on and off (at least I don't think I'll care at first!). I can always install the clutch switch later I guess. Isn't it kind of expensive anyways?

i think it will do more than just save your brakes - when towing you wont have to keep the r's up for the brake to be effective

that is how my brake was hooked up. i loved it that way. and pac has those nice push/pull switches. when i installed the gv od i removed the brake and left the pac switch there for the splitter



edit - some say a brake is nothing more than "a potato in the pipe" and ask "how could one be any better than the other?"

The clutch switch is in series with the on/off switch... so when the clutch pedal is depressed the ECM thinks you've turned off the brake and it won't come on... .

I suggest to all customers that they consider letting their foot rest on the throttle and not let the brake come on during shifts if they have a problem... .

We have the clutch switch in stock if you want them..... but none of my trucks (6) use them... ... Navstars, Fords, Dodges... .

If you have specific questions you can call Jack at 800. 445. 4696 from 730 to 500 M-F on the west coast... there are times he gets overloaded and might need to call you back... .

We were a large Jacobs dist years ago and have been with pacbrake for 20 years or so... .
