1. See figure 10. With parking brake released, rotate the
brake cam (A) forward until it stops. There should be
5/16" gap between transaxle housing (B) and rear
point of brake cam.
2. If adjustment is required, remove cotter pin (early
models had an "elastic nut" instead of a cotter pin)
and turn adjusting nut (C) until proper 5/16" clearance
is achieved. Turning the nut in will decrease clear-
ance, and turning the nut out will increase clearance.
Install cotter pin (or nut) after adjustment.
3. Fully depress the clutch/brake pedal and lock the
parking brake by pulling up on the parking brake
knob.
4. The brake rod spring (D) should measure 2-7/8"
when compressed. Turn the adjustment nut (E) as
necessary to obtain correct spring length.
