FYI brake drum issues - The 1947 - Present Chevrolet & GMC Truck Message Board Network

One of my last winter projects on my 65 C10 was to rebuild the stock brake system with all new parts. I purchased 4 new drums from Rock Auto (2 being Bendix and 2 were Raybestos) made in China of coarse. On my first test drive this spring, I noticed a pulsation when braking. I drove it for a while trying to figure what was wrong, thought maybe a front hub wasn't running true. I decided to have the new drums checked and was told that 3 needed to be cut 4mm and 1 was 5mm to true them up costing another $100 at our local NAPA store. This is just a heads up if you are buying new drums. Maybe buying the drums locally would be an advantage should a problem occur.
Hairball.
