To prevent serious injury or death
resulting from the use of worn park-

attempt to re-new worn components. The parking
brake arm latch is a hardened part. Do not grind or

Installation is in the reverse order of disassembly. Use a
new push nut (or push nuts).
If required, adjust the kick-off cam (3). See the

Tighten the lock nut to 12 - 14 ft. lbs. (16 - 19 Nm).
