There are running differences between the 1932 and 1935-36 mechanical brakes.

These changes are just the ones made from the 1934 to the 1935-6 Ford:

1. The width of the brake lining was increased from 1 ½” to 1 ¾” width. The drums were of the same diameter as before, though the linings were shorter in length. The result is the same braking surface area as 1934. 1935’s wider shoes are supported on the backing plates by their semi-circular ends bearing up against the wedge pins.
2. The new drums for 1935 have a larger number of cooling fins.
3. Wedges of the type formerly used only on the front brakes are adopted to both front and rear for 1935. These wedges are designed to give a ‘self centreing’ action by being of the ‘floating type’. Both shoes self-energise as the wedge bolt no longer works like an anchor. By using these wedges for both front and rear, the speed of brake application is equal. The advantage is that it’s no longer necessary to back off the rear brakes after the adjustment is made.
4. The brake adjusting shafts are slotted with the upper ends of the shoes being a sliding fit in these shafts. Previously, the shoes were pinned to these shafts.


There are two books covering how to adjust mechanical brakes on Ford V8s in 11 easy steps, sourced from original material. Check them out on Amazon's Kindle.
