Rex,

This may help or not! I have a 85 pt40 and when I applied the brakes
hard the tags skid I increased the presure to around 60 psi, they were
at 45 they don't skid now. Maybee your pressure is low or a bag is
leaking on one side, or even a big difference in the weight of the
sides is causing just one to lock up at a time. Maybee a combination
of all where there is less efective weight on that side. What pressure
are you running in the tags? and even what air pressure in the tires
are you running? mains to tags?
