To adjust parking brake
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.
