Power Steering Pump issues...

[quadracerx]

Well.... After doing the recommended bleeding procedure, nothing changed. The pedal still sinks about 2-3 inches before the pedal stops and brakes apply. Not good. So my next step will be to replace the master cylinder. If thats not it, I guess its the hydroboost.

In regards to the hydroboost, since the power steering pump ended up being for a 1986 instead of the year of the truck which is 1988. I looked up hydroboost part numbers for both years and they are different??? From the photos on the NAPA website I cant see a difference? Any ideas?

Thanks,

Steve
