The axle shafts unbolt like normal. The rotors fit over the flange.

My rotor fits over the flange as well. Maybe it's because I've gone from stock, but dont you have to unbolt the flange from the rotor side, THROUGH the rotor?

This is only slightly related to the conversation at hand, but I know for sure that to take mine off, the way it is now, you have to hold a nut at the inboard side of the axle flange and turn a bolt at the outboard side, through the hole I have drilled in the rotor, in order to remove the axle retaining plate.

The rotors come off then use an extension to remove the 4 retaining nuts.

Ok I've found a 2009 hydroboost set up for $50 off of a f450 with 26000 miles. Maybe that will work. Going to check it out tomorrow.

Probably will make my own lines I think.

Also...anyone used a GM saginaw pump?

 

What engine is in your truck. Saginaw brackets are out there for 385 series "460". I want to say 302's as well. I ran a saginaw in my truck with a 460 for ahwile, my cummins also has a saginaw.

 

Dude that's woring on my bronco is going to build me a bracket.

 

I've run a GM Saginaw pump.

Lots of them.

With a few minor changes, all the pumps seem to be the same. You can pull one reservoir off of a Ford Saginaw from 79 and it'll bolt up to a brand new Chevy unit from an Avalanche.

The pressure ports have at least two types, metric with an O-ring and standard inverted flare. I think they are 1" from flat to flat and unscrew and swap if you need to. There are some minor, mostly irrelevant differences affecting flow rate that come from various bypass orifices, right behind the outlet port.

Some reservoirs have long necks, some have decreased capacity, some have remotely mounted reservoirs, but they all swap in my experience. Some of the reservoirs are held on by one bolt and the port, some have more bolts, but every pump I've seen will still accept any reservoir. They have 4 or 5 drilled and tapped holes and if the reservoir doesn't use them, they just cover them up and leave them alone.

The only thing I've seen that's not really a minor difference is units designed to be hard mounted to an engine, like some of the Cummins engines used, have an extended input shaft that allows a driven gear to be mounted. But you're probably not going to accidentally get something like that and if you do, you can sell it online easily.

If you decide to get a junk yard unit, it's likely it'll work fine as-is, but if not rebuilding them is very easy and mostly a matter of re-sealing the thing.
