Sorry, dunno yet. Still putting it all back together.

Hydromax master/booster all painted and installed.

Should be pretty straightforward. Expect that the most complicated part of the whole swap is going to be all the electrical wiring to make the backup pump work. Other than that, adapting the Hydromax master/booster to a deuce is as simple as drilling four holes and making/buying a custom pushrod...

That's essentially what I'm doing, but giving it away. Working with Precision Rebuilders to put together a kit that will include a few custom-made parts, but am also sharing information so that anybody who wants to tackle this on their own will be able to.

The other point of interference was between the electric backup pump adapter and the framerail, so I rounded-off that corner. Then I separated the master cylinder from the brake booster, hosed it down with brake cleaner, and then sprayed it with a coat of rust-inhibiting primer. Headed down to...

Mounted the Hydromax master cylinder and brake booster today. Had to clearance the brake booster where it was interfering with the transfercase mount. Would have been reluctant to do that, but the other side already had a similar amount of material removed, so I'm sure it's alright. Test-fit...

Probably just because it's empty?

Me too! Cab is down in Salinas getting painted right now, but I have a lot of work left to do before this thing will be back on the road.

Anybody?

Bingo! Fits great now. Just need to paint the master cylinder and do a little bit of clearancing so I won't have to offset the master/booster, then drill a few holes and mount the whole Hydro-Max assembly to the chassis.

Reinstalled the stock master cylinder and cycled the brake pedal linkage. The clevis/pushrod is threaded, so the geometry will change slightly, depending on how the linkage is adjusted. Not knowing how that is supposed to be adjusted, just cycled the linkage how it was adjusted when I took it...

Need to start figuring out the pedal linkage, which might only require a custom push-rod, or maybe even just a little adapter that will allow me to mate the stock clevis to one of the threaded Hydro-Max pushrods. Going to reinstall the stock master cylinder so I can cycle the linkage and see...

Yesterday: Received the new 24V backup pump, so now have got all the parts needed to figure out how to adapt this Hydro-Max setup to mah deuce. Unfortunately, the backup pump interferes with the transfercase mount to the point where I'm almost definitely going to need to cut into things to make...

Pretty sure, yes. If you can find two more rotors and calipers. Only thing I can think of that might be a problem is if the master cylinder maybe didn't have enough fluid volume for the extra calipers?

The backup motor might also interfere with the transfercase mounting crossmember. Might end up needing to modify that too.

Three different cleviseses are direct-fits, and the stock pushrod could probably be modified (turned down on a lathe) and made to work just fine too. But if I have to offset the master/booster to one side none of those options work anymore. Could switch over to a single-shear clevis, or have a...

Received the all of the Hydro-Max parts (except for the 24V backup pump which is still on-order). All this stuff actually showed-up a few days ago, but I just finally got a chance to open up the boxes. Not really much else I could ask for. 1 3/4" 50/50 master cylinder with pressure...

Oh no, not at all. Precision Rebuilders didn't charge me any more than they would have for a stock rebuild. There's really nothing 'custom' about the setup I ordered - it's just a combination of parts that didn't come from any one application. They have a big inventory of all these type of parts...

The 1 3/4" master cylinder is going to build more pressure when used with the Hydro-Max 2 booster. It's the most powerful combination of parts, and the stock master cylinder is 1 3/4", so should have enough fluid volume. Gonna give it a try anyway...

Ordered all the Hydro-Max parts from Precision Rebuilders this morning. They have to build a custom master cylinder for me because it's a unique configuration, with all of the specific features that I want to have for this application (50/50 1 3/4" master cylinder, with a pressure differential...
