Any help with wheel cylinder ID?

[CEE1NG_RED]

Hello.

I am not sure which year forum to post this to, but I have a '67 SWB C10 truck that has been Frankensteined together. I find new things everytime I try to work on it. This time, the wheel cylinders (front) did not compress and caused my front brakes (the shoe to not compress in) to smoke and eat to the point that the coating of the wheel drums flaked off.

Anyways, I was wondering if my wheel cylinder came from a 1946 or later model Chevy (possibly a 1 Ton truck) (pic attached); I had taken the driver's side a part to see the cap size and it has a 1 1/8" cap that pushes the pistons outwards.

Also, I have a question on the front brake system set up. Is it missing a e-brake bracket and spring?? There is no hole on the backing plate of the brake system where the wheel cylinder is mounted onto with 1 screw. So I am confused. If it comes with an e-brake, that explains why the shoe did not compress in and causing my front brakes to catch smoke and heat up. But, why didn't it happen when I drove it from Hemet to LB (100 miles away)?? If not, is that my front brake system okay and not missing any parts or springs??

Anyways, any feedback is useful so I can get the front brakes going and completed.

Thanks!! - Alex
