Well I haven't seen too much about the hydroboost systems online and I figured whatever I find out could help someone else with their swap! I'm going to be upgrading the front and rear brakes to 12" discs in the near future so I wanted to redo my braking system so it could make the most of the upgrades. The little 305 I have in the car doesn't have the best vacuum with the cam installed so I wanted something other than vacuum brakes.
First things first I pulled my hydroboost unit and master from a 1993 Astro Van in the wrecking yard. It was still all attached and the system held pressure
Next I went ahead and cleaned up the hydroboost and got a high ratio steering box, jeep steering shaft and a new master cylinder for my El Camino (mine was leaking so it needed to be replaced)
I've since painted the hydroboost and I think the stock master will fit just fine, I'm going to grab a caliper from work and measure it compared to the one off of the Astro Van.
I've also got a fluid cooler for the power steering system (not needed but it was lying around). I've got a good idea of how to plumb everything and also how it should work. I'm going to have the high pressure hoses made at a hydraulic shop and I only really need to figure out how to get a low pressure return into the back of the pump's resevoir.
I'm going to take the old system off the car and hopefully the rod that attaches to the brake pedal isn't a huge problem...I'll let you all know how it goes \/
So far I'm only into this project $25 because I already had everything but the hydroboost, but the hoses should add some to that.
