Well today I swapped in a NEW Napa Master Cylinder. I was going to get one locally here in BC, but the best warranty I could find was a 1 year only! Just across the boarder at the US Napa I could get a new unit with a lifetime warranty! Seemed like a no brainer to me.

Gave it a coat of paint, but as other s have found the lid leaked before I even got it on the truck.



Here you can see the reason for the leaking. The old "Made in the USA" seal vs the new generic no name brand.



I cleaned up the old seal and installed it on the new cap and so far no leaks.

 

The other night I started obsessing over a Hydro boost conversion for my crewcab. I then saw a craigslist ad for a 2000 cummins ram being parted out. Several E-mails, and a phone call later had me over at the guys house pulling a hydro boost set-up!

Was a little disappointing that it was leaking out the back once I got it out and could inspect it.. So I wasn't going to take it, but he was willing to sell it at core charge value. Figured I went 45 min out to his place I may as well return with something.





Nice guy, he bought a nice 90 2wd 1st Gen with the insurance settlement from his 2000. We chatted diesel trucks for a bit before I headed out.

Now to see if I can find a reseal kit for this unit, and then a "How to" on how to Re/Re it.

 

I am a huge hydroboost fan, I have converted both of my pickups. It will be like driving a whole different vehicle! I think every first gen should have hydroboost and it is by far the best upgrade that I have ever done to any vehicle. Good luck on the swap, FYI I have one that has a newer power steering pump with two return lines and the other one has the stock power steering pump that I put a tee in the return line. Both perform the same.

 

Have you seen this yet?

I have now. Thanks for the link Mark!

And Hot Dawg...That seems to be the consensus of everyone who puts Hydro boost on their truck...one of the best upgrades they have done so far!

 

I love the one in my Jeep and it is on the someday list for the Dodge.

 

What is it that makes a big difference by adding HYDRAboost to our trucks. Thanks TC for your input/opinion

 

You get almost twice the line pressure as hydro vac . something like 1500vs 2500 if I remember correctly plus a solid feel air is compressible and fluid is not.

 

any time.

Thanks TC. Are you going to do a step by step? so I can add it to my crew too Thanks.......

 

Yeah you know I will.....

 

It looks so long in the pictures! Almost as if it'll extend beyond the intake horn . I'll be watching for your installation how-to, Brian!

 

I have checked out as many threads on the Hydro boost swaps i can find on our 1st gens. The plastic MC reservoir basically sits up against the intake tube.

Been thinking about if I could make my own shorter bracket, and then make an adjustable push rod from the original Hydro unit, and one from an old brake booster?

 

This may help some.

I had not come across that one....! That pretty much answers all my questions, ideas and thoughts!
