I'm in.

I forgot to bleed the top of the air pack when I bled the brakes. It had been done before I changed the line from the air pack to the distribution block, so possibly there was some air that made its way up. Just a guess. My wheel cylinders have not been touched in 25-35 years, so a leaky one or...

The brake system has been sitting for a few weeks now. The remote master cylinder level drops about 1/8" in two weeks. There are no leaks at the master cylinders, the air pack or the line I replaced from the air pack to the distribution block. I guess that leaves wheel cylinders as the source of...

I was snow plowing with the deuce from 2001 when I bought it to 2015. I would check the brake master cylinder level after a few plow runs and it would be down an inch or inch and a half. I would refill it and never once did I think, "Where is the brake fluid going?" Now, looking at my old air...

Started up the deuce and everything works. The new air side brake light switch did not work and then I realized (duh) the master switch was not set to brake light! No leaks, and after bleeding the brake pedal feels firmer than it did before I started working on the brake system. What is sad is...

Every time I tightened the flare nut, the leak was a bit less. When I received the NOS brake line, there was a red plastic cap over the air pack end. When I removed the cap, I discovered water had infiltrated and there was rust. I cleaned the rust off with steel wool and oil. There was still a...

Yes, I am using the flare nut wrench with the six sides and the narrow opening to go over the line. I'll post an update after I try tightening a bit more. Thanks for the advice, gentlemen.

I received from Big Mike's and installed the NOS airpack to distribution block brake line yesterday. Today there is weeping brake fluid from the distribution block connection and the air pack connection was a bit wet. The connectors are not cross-threaded and I tightened them fairly tight, but...

I traced the line and didn't see any clamps. I was debating holding the block or not. You're right, better safe than sorry. I noticed a DOT spec inline splice on one 1/2" air line above my head. I'll have to start tracing all the brake system lines and determine if any others need replacing...

The block location is behind the air pack, about even with the spare tire. It will not be as hard as some of the work I did replacing the injector lines and hydraulic head, especially that metering shaft. Thanks for the response.

When I installed the air pack, the brake line from the top of the hydraulic side of the air pack to the distribution block was "gorilla tight", as Garrett would say. When I re-attached it, it leaked. I tightened it some more and now it just weeps a bit. I cannot tighten it any tighter, so I...

I thought that would be the case. For all of those inexperienced guys like me, here is a tip. If you have the 3/8" line instead of the 1/2" line for installing the air side brake switch, I realized the fitting screwed into the air pack is 1/2" pipe x 3/8" compression. So i went to the local...

I found an old thread that describes the Balmer AF-8 crimper and how to modify it so the male connectors will pass through it. I found one on eBay so I'm set once it arrives. I may very well be replacing other wiring on my deuce, so having some connectors and the tool on hand will be handy...

I am not familiar with a round crimper. I will do some research.

I am about to install the air brake light switch conversion kit. The white plastic sleeves that go over the crimp-on connectors may not fit over the metal connectors if I crimp the round rear part of the metal connector. It appears that crimping would oval the metal and the plastic sleeve would...

Axle seals is on my list. Brake system first, but then the two systems overlap when it comes to slave cylinders. Probably will be next year, as I am burned out from replacing the hydraulic head, brake master cylinder, and air pack this year, as well as installing the remote brake reservoir and...

Thank you for the detailed information. This was the middle differential. I don't recall the front and back differentials hissing but I may have missed it. I'll check the vents out. In the 23 years I have owned this truck I have never touched them. I'm catching up on much deferred maintenance...

I suspected so. I'll check all the vents and possibly replace them. Thank you for the response.

I changed the gear oil in my deuce differentials. One of them hissed slightly when I removed the fill cap. Does that mean the breather is clogged?

Does anyone know if the hydraulic side of the air pack is leaking, that this is a typical failure of old air packs?
