weird brake setup on CUCV K5

[84K5cedric]

This is an 84 CUCV K5... why doesn't it have a brake booster and what's up with the lines that run from the PS pump up behind the master cylinder? Is this just non-power brakes? But what's up with the PS lines? /forums/images/graemlins/confused.gif /forums/images/graemlins/confused.gif

That is "Hydro-boost". A diesel doesn't make vacuum so they use the pressure from the power steering to hydraulicly do the job. I have the same on my Jimmy.

ok, so tell me... is it a good thing, or should it be changed over to a standard setup in the case of a 350 conversion?

A freind of mine had the booster and did a swap to the Hydro-boost setup and loves it to death. My k5 has 37 inch tires and when I go to stop it takes a little effort to stop.
I have driven his K5 with 42 inch tires and hit the brakes it will all most put you in the windsheild I wish I had that setup on my Blazer.

There is no reason to get rid of it. I find I get great braking with mine, that's with D60 front (big disc's) and a rear disc conversion on the rear. The pedal effort isn't huge, they're not overly sensitive, and the braking seems well balanced.

You may need to find a way to mount the hydro boost resevoir/pump assembly on sbc brackets though.

If the 6.2 is still good I'd just keep it...great motor for rock crawling! /forums/images/graemlins/thumb.gif
