I have a 1959 apache truck with a camaro front clip and the brakes are locking up.Its has a new master cylinder and proportioning valve. After driving for about five minutes the brakes lock up and the truck will not move.Then after the truck sits the brakes release and the same thing happens again. Has anyone ever experience this?

One or two possibilities. Brake hoses internally failing or the master cylinder brake rod is adjusted too long and the return hole for the fluid is being blocked by the master. You can prove this by cracking the line at the master when the brakes are locked to see if they release.
