Well it's obviously breaking more on the left drum than the right. 1.Check equal adjustment on each shoe to drum. 2. Ensure that the leading edge of the linings are cut back about 2" from the end of each of the shoes.  The leading end is the end the piston pushes against not the pivot end. 3.Drums and linings are in good condition and clean. 4.Shoes mate well to the drums. 5.All 4 cylinders/pistons are functioning correctly. It may also be that your shoes and drums need a bit if use to bed in and that the problem you are experiencing will correct itself in use.
