pwr brake booster question

[rodstored-72]

guys,
i am looking for a pwr brake boster assy. for my 72 chevy 1/2 ton 2wd. i called a local yard & asked for a '99 or newer brake assy. from a 1/2 or 3/4 ton p/u. they first asked me if i wanted hydralic or vacum? my first question to you guys is what is the difference & why????

i guess my second question is does anyone have any input as to why this assy. would/would not work on my truck???
and if anyone has done a similar setup on there truck & what kind of truck??

any input from you guys would be much appreciated.

thanks!!

I dont know if it will work on your truck... but you would need the vacum type I would immagine.

I am guessing the hydrolic set up is from a diesel as they have no vacuum, and or heavy duty applications. I imagine you could "make" it work, with enough time, cussing, and a big hammer but why? The 3/4 stuff works good on these and you can get the compact unit to clean up the firwall as well.

The hydralic unit uses power from the power steering pump and is usually called a hydro boost system.They can be handy if you want power brakes and a wild cam that doesn't create enough vacuum.
