Overhaul
INSPECTION1) Move the pad - brake pedal in a horizontal direction with a force of approx. 10 N (1 kgf, 2 lbf), and check that the pedal deflection is in the range of specifications.
CAUTION:
If excessive deflection is noted, replace with a new bushing.
Deflection of brake pedal:
Wear limit: 5.0 mm (0.197 in) or less
2) Check the position of the pedal pad.
Pedal height L:
140 - 150 mm (5.51 - 5.91 in)
Brake pedal free play A:
0.5 - 2 mm (0.020 - 0.079 in) [When pulling the brake pedal upward with a force of less than 10 N (1 kgf, lbf).]
3) If it is not within the specification, loosen the lock nuts of vacuum booster operating rod, and rotate the rod to adjust the pedal height L within the specification.
4) Tighten the lock nut.
Tightening torque:
Operating lock nut: 22 Nm (2.24 kgf-m, 16.2 ft-lb)
