Grabbing SM brakes

My super major brakes are ok but the off side brakes grab if I go to stop in a hurry, what would cause this ?
From a previous reply
Brake adjustment on the Super is straight forward. First slacken the self-locking pull nut in the linkage so that the brake pedal goes right down and there is nothing pulling on the linkage. adjust the screw on the bottom of the brake housing until it is up tight then back off 1 and 1/2 turns, then tighten the lock nut.
Place a 1/2" (13mm) block of wood between the upper side of the pedal and the foot plate. Adjust the self-locking pull nut until the pedal can just be eased off the block. Only take up the free play,do not overtighten. The pedal should feel springy.
Repeat on the other side.
Test by locking the pedals together, drive forward in first gear at about 1300 rpm. Apply the brakes with your foot in the centre of the two pedals. If she pulls to one side or the other tighten the pull nut on the opposite side until she pulls in a straight line.
After a time the brakes will tend to lock on when applied. This is a fault with all makes of tractor that use these Girling disc brakes. When this happens, strip out the brakes and clean out the dust from actuators and housings. Be careful, the dust may contain asbestos.[/quote]
