I've got an older GMC P/U "custom camper".If it has no camper or other load the rear wheels tend to lock up real easily when braking.With a heavy load the brakes seem very good.I would imagine that this condition exists with a lot of pick-ups but my local parts stores don't have any kind of adjustable proportioning valve.One guy told me that Ford Motor Sports has one for racing,but I doubt this would be affordable or necessary.Due to the nature of my work I might have an empty bed one day and 2 tons the next,but 75% of the time it's empty and I'm losing tread on my rear tires. Any suggestions?
