There are disc brakes out there for them. But I'm much more interested in having dual circuit for safety. The drum brakes are completely suitable to stop the truck. Now, upkeep, they probably would be easier to deal with. I think there's several threads about disc brake conversions. I wouldn't...

The MC part number I ordered is MC39577 (It was on page 2 of this thread). I don't have a part number for the hydromax, as it was a used unit off ebay from a International truck. The only downside to that unit is that it's a 12v unit. I plan to just plug it between the batteries though. As...

I started reading that, but it's a rather lengthy document. Is there a part in there that states from the government that the brake diaphragms and/or cans have to be replaced every year?

Forgot to post this yesterday, but my hydromax booster came in. Happened to have a plate that matched two of the mounting holes and had a large opening for the pushrod. Just had to drill two holes and now I have a reinforcement plate to install it. The feed side of hydraulics uses a odd fitting...

Dunno. I have 1/4 hardline here. I replaced the rear hardline with 1/4 on mine this week. Was planning to just run 1/4.

Yes, we have the same MC save for the resv. Use a bubble flare there instead of a inverted flare.

I'm going to just use the right size fittings on the new lines. No adapters. Sent from my SM-G965U using Tapatalk

I'm going to be adding power steering to my truck. So I'll be installing a LDS PS pump. But one could also build a bracket and hang a GM style PS pump too if you needed. I plan to mount my MC/Hydro-max booster to the firewall. I'm going to use pillow blocks to hang a 1" shaft from the...

I've explained it in post #83. You have to have two air packs. What fleetmech mentioned and jeepsinker is using a air actuated MC from a trailer to split the brake system. My concern is that if you lose the main MC, you've lost your trailer brake MC. Because no fluid pressure into the...

Those valves still need two inputs for the two outputs.

No, because you'd have to route both brake lines into a single line if you only have one airpack. The air system and tanks are just to supply air to the airpacks. Edit: Here's a diagram from the brake line side of things and how the normal system works. 21-23 is the line out of the single...

The electric pump is a backup in the event there's no pressure from the PS pump. In that video I could see the hyd. line feeding into it. And he had a waterloo PS setup, so I'm sure he had the hyd hooked up.

No. The airpack has only one inlet and one outlet for the hydraulic (brake) fluid. The Air Force dual circuits use two airpacks.

I guess I'm overthinking things again. Because I found other examples of the same routing.

Can someone give me some advice on the Hydro-max booster setup? I am leaning that way because with no hydraulic pressure the motor will kick in to assist. My wrinkle is the hyd. plumbing circuit. From what I see, the outlet of all these hydro-max boosters are for low pressure returns. I plan...

There isn't one. Due to the space allowed in the area. And the bracket design. Then you still have to deal with a second airpack.

I'm honestly thinking more to the hydroboost setup. There's been a many of deuces towbar'ed without air brakes on them. My only other truck that could "safely" do it would be the 5 ton. So it has a weight advantage. A single hydroboost on the wall and simply two lines down to tap into the...

On the drive home I just realized one trade off going that route. I know it's not often used, but the airpacks can have a air supply plumbed into them to make towbaring the deuce easier. (It's a add on to the line at the airpack, so it's not factory) The dual airpack route would allow for...

I think I've decided the process I'm going to take. I was thinking about dual airpacks. That would make things "simple" when it comes to the trailer air side. But it also doubles the amount of air packs in the system which historically have been "problematic". Not to mention they're not...

I have two or three of those laying around. That was the path I was going to take at first. But I gave up on the idea. I don't like the thoughts of losing air pressure and having no physical connection to the brakes. Yes, I know in a air brake system you have no physical connection. But in...
