Isnt Centric made in China also?
I bought some spares but haven't used them yet
Centric is made in Taiwan, and it is new, not rebuilt, and they don't have core exchanges/charges as they don't rebuild them.
I have had issues with their wheel cylinders having the same part number but not being the same part, specifically a different bore size, other than that I have not had any issues with there products.
That said I have always been able to find what I need in the Centric brand for my Datsun 521 trucks, they have stock type clutch and brake masters that work after installed, they also have had wheel cylinders for my dually axles, but them parts are the ones I had issues with bore size, I had to go back and trade for others till I found two with the same bore size, they worked fine, in the end though it was not the wheel cylinders that were my issue, it was the brake master that was going bad, don't know the brake master brand that was in the truck at that time, it likely came from Baxters.
