I recently bought a 1949 Chevy 3600. I admittedly have limited automotive knowledge, but decided to teach myself. The truck had been sitting for years. The drums took a lot of convincing to get off, I used a lot of penetrating oil to get the two flathead screws loose. We decided to replace the wheel cylinders, huck brakes and brake springs on the front. I put everything back together, one side works fine, the other not so much. I have the wheel cylinder pistons fully retracted, the drum slides on easily, and spins easily, until i put in the 2 flathead screws. Once those are in the drum won't spin at all or will with significant drag. I rechecked my assembly which looked correct. I tried switching the drums from one side to the other thinking this would help me d32cide if the drum needed to be turned down. The problem persisted on the same wheel.
Someone I asked suggested that the new shoes maybe misshapen or the wrong size and that is the problem. Measuring the thickness they seem right. Does anyone have thoughts? Did I put it together wrong? Should i have the drums turned down? Any help is appreciated.
