9. Engage the parking brake. Measure the overall

length of the compression spring (Fig. 167).

Measure the overall length of the compression

spring. The correct length should be between 1-1/2”

and 1-9/16” (3.8 and 4.9cm). If the spring length is

within this range, no adjustment is needed. If it is

not, proceed.

11. Disengage the parking brake. Rotate the drive wheel

release handle to the released position. Turn the

wheel hub by hand in both directions relative to the

caliper; no drag of the caliper pad on the wheel hub

is desired.

12. After adjusting the brake, cycle the brake handle a

minimum of six times to allow the cable to seat into

the sheath and mounting tabs. Recheck the spring

length.

13. Rotate the drive wheel release handle to the

operating position.

10. Hold the end of the threaded rod with a tool and

adjust the lock nut until the spring length is between

1-1/2” and 1-9/16” (3.8 and 4.0cm) (Fig. 168).

Note: DO NOT allow the cable to turn when the nuts

are being turned.
