Parking Brake Adjustment - Snapper 18HP User Manual

PARKING BRAKE ADJUSTMENT

1. Disengage the PTO, stop the engine, block the
front wheels, remove the ignition key, and engage
the parking brake.
2. Elevate the rear end of the unit and remove the
rear wheels.
3. Check the brake spring (A, Figure 27) length (both
wheels). With the brake engaged the compressed
spring length should be 2" (5 cm). If not, adjust the
locknut (C) to achieve the compressed spring
length of 2" (5 cm).
4. After achieving the correct spring compression,
check the set collar gap (B). With the parking
brake engaged, the set collar gap should be 3/16"
(5 mm). If not, loosen the set collar screw and
move the collar to the correct position.
