ADJUSTMENT



See Figures 6, 7 and 8

The parking brake cables must be adjusted any time one of the cables have been disconnected or replaced. Another indication of a need for cable adjustment is if under heavy foot pressure the pedal travel is less than 9 ratchet clicks or more than 13. Remember that the brake shoes must be properly adjusted before attempting to adjust the parking brake cable.
