Review on Cardone 532776 Remanufactured Power Booster by Dexter Rasberry

Very disappointing. I received and installed this item and a new master cylinder. My problem persisted (hrd pedal on fast press, great brakes on slow press) and I've been messing with it sporadically for months. Knowing the booster was new, I tried many other things. I chose not to send my original for core loading - fine too. I sent the old one in for an overhaul and when it came back I installed it. Problem solved. It's long past the return date but thought I'd write this review, hopefully someone else doesn't fall into the same trap. I think the QA/QC for this part is not very good.
