BRAKES STX30 & STX38
(SN —210000) REMOVAL/
INSTALLATION

NOTE: When the brake pedal is depressed, the set

compression spring puts an adequate pressure
on the brake lever. The brake lever, by cam
action squeezes the brake pads against the
rotor. The rotor is splined to the shifter/brake
shaft. If the rotor cannot rotate the shifter/brake
shaft locks the differential and axles from
moving, providing the braking action.

Removal

1. Remove right rear wheel.
2. Remove linkage from brake lever.

3. Remove cap screws, rotor, and brake pads.
4. Check brake linkage, pads and rotor for wear,

binding and dirt.

Installation

5. Apply LUBRIPLATE® to pins.
6. Install pads.

7. Install assembly to transaxle using cap screws.
8. Install linkage in brake lever.
9. Insert feeler gauge between rotor and outside brake

pad.

10. Adjust lock nut to get 0.254—0.508 mm (0.010—

0.020 in.) clearance between rotor and brake pad.

11. Install right rear wheel.
