Parking Brake System: Testing and Inspection
BRAKE PEDAL AND BRAKE SWITCH ADJUSTMENTBRAKE SWITCH CLEARANCE
Screw in the brake switch until its plunger is fully depressed (threaded end (A) touching the pad (B) on the pedal arm). Then back off the switch 3/4 turn to make 0.9 mm (0.04 inch) of clearance between the threaded end and pad. Tighten the locknut firmly. Connect the brake switch connector. Make sure that the brake lights go off when the pedal is released.
PEDAL FREE PLAY
1. With the engine off, inspect the pedal free play (A) on the pedal pad (B) by pushing the pedal by hand.
Free play: 3 - 8 mm (0.11 - 0.31 inch)
2. If the pedal free play is out of specification, adjust the brake switch (C). If the pedal free play is insufficient, it may result in brake drag.
