I have a friend with one and I'll ask him if he has a manual and if it covers adjusting the valve.
I have done similar to Lang suggested to adjust it and then try on a loose dirt road to see where it locks up.
A couple of years ago the local servo stopped doing annual heavy vehicle rego inspections and I had to take the Oka to a truck place and they put it on a rolling road to test the brakes, first try the rear on the Oka couldn't even slow the rollers down, I hopped under and let the proportioning valve arm go and sit up against the floor, the brakes worked well then! Since then I've fiddled around with the adjustment after resetting the rear springs and it is now braking pretty evenly.
I've found that if the Oka starts to suffer from squeaky brakes under light brake application then it is a sign that the rears aren't braking as hard as they should.
