The rear axle bearings do not get lube from the differential in you truck; there is a leather seal inboard of the bearing that keeps the differential lube out. The ball bearings use a cup grease and the lube chart says to turn the grease cup every 1000 miles. The zerk fitting on the spring to axle housing is to lube this area so the rear axle will rotate separate from the springs; lube with chassis grease. Get your self a shop manual original or reprint it shows the above and gives you all your brake information. Your front brake adjustment is the same as the master car for 1935.
