Super A brakes

First you need to jack up and securely cribb the rear of the tractor, not under the drop housings. Remove the rear wheels, weights, and center disks. Then remove the drop housings by taking out the bolts that hold them to the transmission (left side)or axle extension housing (right side). The brake bands should be be exposed and the rest you should be able to see. A word of caution, the drop housings are very heavy, plan on getting some help. A trick I used is to replace a couple of the bolts with longer ones before removing the others then you have some support as you slide the housing out from the tractor. I cut the heads off them so I could use the long bolts to act as guides when I put the housing back on. You also should check the rear axel grease seals and bearings while you have it that far apart. You don't want gear oil to ruin you new breaks. Good luck, Daniel.
