Are these the stock style FRONT brakes for my 53 1 ton? They have obviously been replaced sometime since they show almost no wear, but they seem like a more modern setup. They measure 12". # on the wheel cylinder is 5453927. the reason I ask is because there is a broken spring and I need to know what to look for as a replacement.
