Pedal height
The height of the pedal position is the distance of its pad from the floor (refer to the accompanying illustration).
If the parameter in question is outside the acceptable range (see Specifications), the appropriate adjustment should be made (see below).
1. Before measuring the brake pedal height, make sure that the pedal is fully released, then start the engine and depress the accelerator pedal several times to activate the brake booster. Measure the pedal height. If necessary, make the appropriate adjustment by loosening the lock nut and releasing the lock bolt/brake light switch, then loosen the push rod lock nut and rotate the push rod until the pedal height is in the middle of the permissible range (refer to the accompanying illustration). Don't forget to tighten the locknuts.
2. After adjusting the pedal, screw the locking bolt/sensor-switch until it stops in the pedal assembly lever (without tension).
Free pedal travel
Free travel of the pedal is the amount of movement from the top point to the point where a feeling of resistance to pressing occurs (refer to the accompanying illustration), i.e. before the start of activation of the hydraulic drive of the brake system.

If the measurement result is outside the acceptable range, appropriate adjustments should be made (see below).
Before measuring the free travel of the brake pedal, depress it half a dozen times with the engine off. Loosen the lock nut and rotate the push rod until the desired result is achieved. Tighten the lock nut.
