The effort increase on the pedal has to do with the larger master. With the increase in the bore diameter the master creates more psi in the lines by pushing more volume but it takes more mechanical advantage to do so.

I wasn't planning on doing the hydroboost for a while given the weather but this weekend has been in the mid 60s, so I decided to do some more work on the truck. I could have done the whole hydroboost conversion this weekend but the dealer didn't have the PS pump reservoir in stock. They wanted $40 for it and it would be here Monday.
Instead, I changed out the front rubber brake lines that I couldn't get off last time. An 11mm flare wrench fit much better than the SAE one I was using.
I have a few more questions for y'all, though. The fluid that came out of the hydroboost was awfully dark, would that mean a problem? It also had a very nasty odor to it. Which line should the filter and cooler be installed on? I know it needs to be on a return line but now there will be two of them.
Thanks.

ah that's too bad.the power steering/hydro system should be flushed every year really.
the hydroboost unit should be treated like the ip for the engine.with very close tolerances that can cause trouble with very little contaminants.that's why i installed a filter along with my cooler in the return line.
what do you mean you'll have two return lines?

oh,the one that comes up from the steering box you just hook in directly.
you want you cooler/filter in the return line after the hydro.
you don't want to have to frig with extending the ps box line,making a loop and hooking it in back under there for anything.

OK, I see. I like your little cooler that you have installed. I want to install mine before the radiator and if it is at all possible, I would like a small spin-off type filter. I may be going overboard but I don't want to have over heating issues and I would prefer to spend $40 now on a filter and head than $20 for a filter every year for the rest of my life. Yeah, I kinda like my truck...a lot...

OK this is probably a dump question but what is hydroboost? I have read several threads on it and everyone talks about where to get parts and how to install it but what is it? How is it different from a regular brake system and why do you put it on your truck.

I picked up a plastic one at Autozone for $9.99 a couple weeks ago when I put my saginaw pump in. The pump seems nice, is quieter, doesn't leak. Unfortunately, it looks like the steering box is leaking again

you can use a spin on type filter system too if you prefer.

OK fellas, I can now join the hydroboost club!
I belted out the whole job in about 5 hours and that was taking my time and enjoying a few cervesas and a trip to the parts store to get a new brake fluid reservoir because I couldn't get the old one off.
I have the stock pedal installed right now. I find it stiff but the truck stops very quickly and I don't have to push very hard. If I did push hard, all of my crap in the truck would be in my lap! I already have to re-secure the spare E4OD in my bed because it came loose during testing.
I don't have the cooler or filter installed but I plan to add those to the system soon. After buying the $45 reservoir, I only had enough money to do with what I had. I still have to check for leaks but noting blew up during my testing, so I am confident I am good to go.
I may decide to swap the stock pedal for the HB pedal but I need to research more about the brake light connector and the cruise vac dump connector before I attempt that. Also, the pedal I have is from a 5 speed, so it is smaller and will definitely look odd and be harder to find.
