1953,
you can buy or have rebuilt, just about anything on your original brakes except the drums. The drums are not made. However, I believe the drums for the 3/4 Ton are available for 53 and up. There are no quick kits to put discs on the front of a 53 1 Ton. Also the IFS kits are designed for the 1/2 Ton but that might not be a problem. If you could go with an IFS, discs would be available.
