I want to hear some opinions on people's preferences. This would be to swap out the brake system on your deuce, get rid of the master cylinder and airpack altogether. What system would you feel safer with? All dual circuit sized for a medium truck of course. 1) Off the shelf dual circuit...

HN6, you did a pretty nice hefty job of putting that bottom plate on there for sure. I was wondering, if a person were feeling a little lazier, if you could just mount the plate across the bottoms of the U-bolts that hold the springs on. It'd be 8 pretty big bolts.... plus I believe there are...

Ok, now I think I understand the garrison unit. What a strange unit. It basically replaces the drag link and is pressure sensitive, diverting hydraulic pressure to an assist ram when the pitman arm pushes on it. When you let go of the wheel, the pressure on it will reduce and allow the steering...

This is the basic diagram they have on their site. Instead of the rack and pinion though, that would be your steering box. Then the hydraulic lines would go to your assist ram. They sell nice little spline adapters on their site as well, so the steering shaft mods would be pretty easy. If you...

After looking at power steering stuff for a while. I noticed one option that might be worth looking into. It's called a power steering servo. It's the same rotary valve that you would find in your normal powers steering box, but a stand alone version. You can simply throw it in your steering...

I believe it depends on the system. At some point, I read that you still can turn some, with difficulty, with a good ram setup like the PSC system above. Eh, not convinced in theory, but I haven't' had time to check on how an orbital valve actually works. One thing I do like about this system...

I'm considering the style of system you did over the other traditional power steering systems out there. 3500 bucks and all that work seems a bit much. Plus all the downtime on the truck. it looks like you could build your setup in parallel, leaving most of the original components in place in...

I've taken just the drum off before. I had just done the hub with new seals and all that. I sealed the crap out of the keyway too, and I did not want to redo it. The brake shoe return spring broke and I had to get in there. Replaced the wheel cylinder too cause it got all ate up from the scrap...

I know this is an old thread, but there doesn't seem to be any others like it ( for the multifuel). So, I bypassed the the fdc on my pump and yes, its like a whole new truck! Clearly, its turned all the way up now, or at least way up. Ive got this steep hill up to my place that I could not do...

After pouring over the internet for a couple weeks now, it looks like no one manufactures a valve like what I want. There's nothing out there but damn velocity fuses. The closest was Parker's quantity fuse. Used to be watterman. Model G8381-8 type1. But they are still a little big, the smallest...

My understanding is that dot 5 is compatible with all common seals. I doubt they are using anything that would be a worry.

From what I can tell, Parker Hannifin are the only ones that actually make the quantity style fuse. They seem to be a very rare item indeed, and theyre for aerospace applications. They are what we'd want, but are very likely out of budget. If they would even sell them to us. Maybe I'll call to...

I forgot to say that I did find a way to make an off-the-shelf proportioning valve work. All you have to do is put put a check valve on each line going into the proportioning valve, after you split the line from the air pack. Then make return lines that t-off from each output line and bypass...

The stroke volume of the m35a2 master cylinder is about 3.75 ci. Thats a 1.56" stroke at 1.75" diameter. I designed the dual cylinder part that would split the front and rear systems effectively, with bleeders, fittings, and all. It is spec'd to run on a little bit more volume than the master...

Ok, I made a mistake folks. An off the shelf proportioning valve will not work due to the double inlet if it came from a T-junction. The brake fluid would always back-route at the T to the leak in that case. I will have to machine one of my original concept that will work from a single source.

I will. Heres a lil drawing to explain the concept. Looking at the schematics online is not clear at all. If one side loses pressure, the center piston will be shoved over by the pressure on the working side and shut the lost side down. It would have springs on each side. The reset button...

I looked at how the proportioning valves you were talking about worked. The ones with the reset. They're a combination valve. These would actually do the same thing as i was trying to achieve, and they're fairly cheap. They also have a warning light sender already on them to tell you when one...

I'll have to look into what you were saying the chevy's used. They may already have an easier solution. Here is the idea for a front back split system. If on fails, the reservoir piston will bottom out and shut that line off. The bottom volume would be for the rear, larger since it has twice...

Offhand, does anyone know the volume of fluid that these brake cylinders use on a stroke? I could machine a six piston in line unit pretty easy. I'll CAD the idea up and post it. See what you guys think.

I was thinking about how to cheaply reduce the risk of individual failed brakes at each wheel. What i came up with is a kind of check valve that would in a sense limit the volume of fluid you could hemorage on each line. It would be based on the amount of fluid that can be used by a brake...
