Should I change the master cylinder? I am assuming that no back pressure probably means all the rubber seals are bad from the power steering fluid? I picked up a new one from Napa but it has a plug on the side, I think for a sensor, but I don't have that on the old one???

 

Not sure about what plug your talking about, I would make sure you have the right master cylender.
Yes I would change the master cylender. Make sure you bench bleed it bafore installation.

 

Ok I changed the Master Cylinder and bench bled it, but nothing changed so I broke down and called the shop. They told me that because there are rubber parts in the ABS (mechanical part) that it and all rubber parts must be replaced due to the power steering fluid. That means everything from the master cylinder to the wheel cylinders have to go...ouch. The ABS has two parts a mechanical and electrical. This will be my most costly mistake ever she is heading to the shop Saturday.

donations welcome...lol

 

Bummer dude, but thanks for the update.
