4" remote mount exhaust brake
4" remote mount exhaust brake
Who has done this. I notice that only BD and pac brake make them. How do you like it. Is it worth getting or not? I was looking at the BD on since it is a little cheap and I had a turbo mount pac brake but could never get it to work brought the truck used and had it on it.
I have one and like it. Works great. The BD brake is one of the two (PRXB is another) that provides good braking in the low RPM range. I routinely use mine at 1300-1500 RPM and it provides for very smooth downhill descents. I tow 10,000# and it makes driving in the mountains stress free.
I installed mine in the stock piping using BD 4" to 3.5" adapters, they will ship them as part of the brake setup. You need to tell them what diameter your pipes are and they will send the right flanged adapters.

I had a BD turbo mount brake for many years. I really wish I had went with the inline one instead. Then I would at least still have with the turbo change.
I would have no qualms using an inline BD. That thing is HUGE in person. lol

When you turn On the switch the brake comes on immediately. You hear the compression instantly (0.5 s maybe) and start feeling deceleration in another second or less.

Ok, here goes:


I had a welder at work weld on the bell pipe extensions after I measured twenty times, cut once myself. I took out about 8" of pipe.



The small switch on the aluminum bracket is the lighted switch that comes with the brake. I intended to do something nicer later but truly, there is nothing more permanent than something temporary... its still there.

I decided to keep the solenoid away from dirt and although instructions call for mounting it under the cab, I placed it on the firewall. The nylon tubing included with the brake was plenty long enough to allow this.

Close up view of the solenoid. When I first installed it, even though I (think) I followed the instructions closely, the brake activated immediately once I started the engine. Naturally, I freaked out but then shut the truck off, swapped the two tubes going out of the solenoid and everything worked as it is supposed to after that.

BTW, the part number for the 4" inline vacuum activated brake was not on the BD web site. I called BD trying to get a feeling for what dealing with them would be like and spoke with Pat (he is here on this forum too). I told him that I have a 98.5 stock truck but may want to mess with the turbo lately. He immediately recommended an inline version of vacuum actuated brake, part number 1037136. They also have 4" inline air actuated version, just like PRXB but much simpler in design, while accomplishing the same. I did not want to mess with compressor installation, so I went with this one. Absolutely no regrets.
I have a PRXB and so far I like it. I did not use the PacBrake air compressor or their electronics stuff.
I installed a larger capacity ViAir system that included a 2.5 gal tank for the same $$. For brake control I used a Cummins stalk switched mounted on the shifter.

Screaming, I am sure I got mine for a bit less. I called BD and talked to Pat. It was cheaper than from a dealer.
You will need to connect your controller to the cruise control wire. Take a look at several instruction booklets on BD web site: the one I received with the unit was for a wring unit and gave a lot of information that was inaccurate or did not apply.

I just installed my larger turbo, and I am looking at the BD remote vacuum exhaust brake. After seeing the pictures here, I am wondering if the brake can be installed closer to the turbo? Maybe in the dowpipe?
Are there any more users of this rmote exhaust brake, that have installed it closer than the transfer case?
Thanks,
Troy
