iTrader: (4)

Hydroboost installed on a 2 door tahoe. The whipple and intercooler will be back on in a couple of weeks.

No leaks! Yay. After doing all of the bleeding procedures I started it up and the engine wanted to die. Doh! I forgot to plug the hose that went to the vac booster (capped it off on the intake manifold). Started it up again and all went smoothly. I haven't installed my cooler yet because I need to figure out where to put it but it will be installed soon.

Parts:
- Hydroboost and Master cylinder from local junk yard (98 HD truck)
- New AC Delco steering pump for a hydroboost truck
- Ebay Mounting plate with centered whole
- Hydratech aeroquip hose and fitting kit for my application
- Various stainless nuts and bolts from mcmaster
- 3/8-16 thread die for the hydroboost pushrod
- Ac delco brake light switch
- Steering and brake fluid

I took the snap ring off the unit and unscrewed the retaining nut with a big adjustable wrench and test fitted the new plate. All fit perfectly and the holes of the new plate matched the stock plate holes.

I bought the plate from ebay from the seller sterlingworth16. It is 3/16" thick steel.

I cut and threaded (3/8-16) the pushrod making it shorter by +- 5 mm. Once I get my vacumm booster off I'll measure and adjust the rod to the same length. The joining nut is stainless and 1-1/8" long. By doing this and using the center mounting plate, I can reuse my stock brake pedal.

End result:





Hydratech hose and fitting kit for a 99 tahoe. These are Aeroquip TFE high pressure hose and fittings. Great service and packaging on hydratech's part.

Filthy!




Still need to tidy up some odds and ends and bleed the brakes.
