Hydroboost Installed
 

So yesterday morning I finally buttoned up my Hydroboost setup.

The booster was out of an 84 1/2 ton diesel pickup. Since my engine only makes 7-8 in. of vacuum, this has really made my brakes a whole lot better. Not to mention I can reach my clutch master cylinder now that the globe is finally gone.

I tried to take a few pics of the important steps, but forgot most of the small ones. Ill post them later as they arent online yet. Just felt like sharing.

Very cool. Let us know how it works over the long run. I'm a fan of the hydroboost over electric vac pumps because they are just way too noisy for my taste.

This is after I cleaned up the unit and bored out the master cylinder mounting hole large enough to mount a thirdgens master (the master cylinders on pickups are smaller in diameter) I also added a larger return spring for a faster pedal return.

After I removed the original globe of a booster.

Had to cut the original pushrod and connect it to the hydroboost unit as the hydroboost has a larger hole for the pedal end. I decided to attach it in such a way that made it adjustable. I then made a plate to attach the unit to the original spacer that attaches to the firewall. I made this plate out of the license plate mounting surface of a factory 1982 F150 bumper heh. I also used a hub nut off of a dana 60 to attach the unit to the plate as they share the same thread.

Had to cut a small portion of the original rubber tube-like thing in the spacer (after I ground off the rivets attaching it to the vacuum booster) to make room for the hub nut, the fit was nearly flawless.

This is the final product. (for now, I still need to make and use AN lines as I'm still using the stock 84 Sierra lines.) The fit is really nice and makes clutch work much easier.

I know its only been a day or two, but I love how the brakes feel, they feel more responsive (It doesn't make sense to me as the pedal travel should be the same) and much much more consistent, but I think thats mostly because my engine only made 7 inches of vacuum.

Any comments and/or questions welcome.

Almost forgot, I also rebuilt my power steering pump and added a double return reservoir.

Nice work, looks great!

I'm sure it'll look a whole lot better whenever I am able to replace the stock lines from the pickup truck.

Welcome to the club. I love the hydroboost brakes in my car. Nice job!
