Ditto here, mine did exactly the same thing . Your image looks 100% like mine did. Everything I have purchased from Centric absolutely blows, especially their brake parts (not just the Z32, but my wife's van and my truck brakes). The Z32 master cylinder I purchased a few years back is hands down better, and it looks just like the Raybestos brand. Unfortunately I cant remember where I purchased it, as at that time it was much more limited on choice.
