LS 80Vette

I just changed over to hydroboost from hydrotech and now I have very very hard steering and I have to apply very very hard pressure to stop with just moving at idle speed being in drive. I had the steeroids R&P completly out so the system was dry when I started going through the bleeding process. I followed the bleeding procedure that was provided with the kit. I even redrained the system the best I could and started over. Both times when it came to start the engine for the first time after lock to lock turning of the steering for atleast 30 times, the pump got lots of tiny little bubbles, left it set 15 minutes and the bubbles went away, restarted the engine and no more bubbles. But still very hard to turn the steering ( need a two hand and arm strenght to turn) and still need to stand hard on the brakes to stop ( it barely stops ). Could the system still have air bubbles? ................very disgusted at this point.

Yes, sometimes it take a day or two to work it's way quiet and air free.....normal for lines being open....

UPDATE..... Problem is fixed, I accidently put the power steering valve and spring reversed in the pump, everything is operating good now, steering and braking.

I have Steeroids and I'm in the process of switching to Hydroboost too. I'll remember to be patient with the bleeding process.

Thanks for posting!!
