Pac brake low hold bck

Just bought an 04 and it came with a pac brake remote mounted. You can pull toggle and hear brake turn on but when slowing down it doesnt seem to hold the truck back at all. What could cause this?

Remote mounted exhaust brakes are not as effective as turbo mounted. They take longer to engage due to the larger volume of space between the EB and the engine, and they dont seem to offer the same retarding power. But that said, there may be something wrong with yours and I'd suggest giving Pacbrake a call.

Ok. I kind of figured remote mount wouldnt be as efficient but this is no more than what not having the EB on does. Ive been in others that were much better. Ill give them a call tomorrow

I have a PRXB PacBrake mounted in-line and it works just as well / the same as when I had a turbo mount. I don't notice any lag in it's operation between the two. I had to go to the in-line set up when I went to compounds. I would think something's up with your set up/install. Like you said, give PacBrake a call, their service is top notch. Good luck.

I have the PRXB PacBrake that I moved from the back of the turbo down the the bottom of the downpipe. I did this when I installed my compounds and it works the same in the new location as it did hooked directly to the back of the turbo. You may have an exhaust leak between the brake and the turbo.

Well turns out the vband where turbo and downpipe connect is leaking which is why brake is working poorly. Problem is it is so rusted on there i cant budge it
