It has a single master brake and a power booster to duel caliper front disks and single caliper rear discs. I hav a problem with the brakes locking on. I thoiught it might be the booster so i changed it. The locking up still happens. Do I need a proportining valve and if which one is recommended for our cars.

Simple test: When the brakes are locked, jack up front wheels and make sure you can't turn them. Crack the output booster line and see if caliper pressure released. Lock them up again and crack the MC output line. If cracking the MC does not make a difference, it's the booster. If neither, then the calipers may be the culprits. 
Found the problem. The origional brake master in the tiger seemed to be not really origional and was seeping fluid. I changed it to a new replacement bought some years ago and added a spacer between the master and the firewall.. Seems I have found the problem.
