Darrell,
If you sit with your feet on the brakes, do they hold, or do they slowly move/depress? If they do, you may have leaky seals in your wheel brake cylinders. If they don't, you probably have a parking brake valve problem.

Darrell,
Not sure which parking brake valve you have, but I had problems with mine - Matco - and your thoughts are what solved my issues. The lever on mine was attached over a square cut end of the valve actuator rod. It could be fitted in one of four positions. I finally decided to disassemble the valve and see at what position the cam fully pushed the locking rods - not sure of the terminology, but fine after determining the correct orientation of the lever.
