The original GM P/N 12345347 fluid is apparently hard to find. I found it listed on Amazon a few months ago, but the shipping date kept getting pushed back until they out right canceled it. I've seen you can use DOT 3 brake fluid, but it's missing additives, which can cause squealing. I need to change my fluid, what is the best replacement fluid? Or does anyone know where I can buy the original #12345347 (I already checked Jerry's, White's, Ebay, and Amazon)?
