Jack up unit and support properly with jack
stands. Allow clearance to work at rear
transaxles. Before making any adjustments:
Set park brake.
Measure the distance between the rod swivel
pin and the brake arm washer. With the brake
engaged, there should be a gap of 1/8” to 1/2”
(3 mm to 13 mm) between the swivel pin and
the brake arm washer.
If measurement is out of range adjust as
follows:
Disengage park brake lever. Remove
retaining clip and remove brake arm by
pulling horizontally from the IZT splined shaft.
Rotate brake arm on spline “rearward” to
increase brake tension. Rotate the brake arm
one spline “forward” to decrease brake arm
tension.
Reinstall the retaining clip and recheck gap
between rod swivel pin and brake rod washer.
Repeat the procedure on the other IZT.
