Pedal Height Adjustment
1.Measure the height of the pedal shoe position relative to the floor panel (excluding carpeting). If the measurement result is out of range (176÷181 mm), make appropriate adjustments (see below).
2. Disconnect the electrical wiring from the brake light switch.
3. Release a counternut and take the sensor-switch away from a pedal so.
4. Release the locknut of the split finger of the pusher rod and by rotating the latter adjust the height of the pedal position, - rotate the rod with pliers. After achieving a satisfactory result, tighten the locknut.
5. Return the brake light switch to its original position (see Section Replacement of the gauge switch of stoplights) and tighten the locknut.
6. Connect the wiring to the sensor-switch.
7. Check the correct functioning of the brake lights (see Section Replacement of the gauge switch of stoplights).
Pedal free play adjustment
1. With the engine off, depress the foot brake pedal several times to release the residual vacuum in the vacuum booster.
2. Having completely relieved the vacuum in the amplifier, press the pedal with your hand and evaluate the amount of its stroke until resistance occurs. The required value is 3÷8 mm.
3. If the pedal free play is too low, check the correct adjustment of the brake light switch.
4. Excessive play is usually due to wear on the split pin/pin or pedal support bracket. Replace defective components.
