3) Separate and isolate the connectors
NOTE = It is very important to isolate the connectors so they don’t touch each other.
4) Place the Black cable’s screw like is set originally. (Screwed in the pedal) 2

5) Spring Adjustment
If you want the pedal backs up slower to its initial position, let the adjustment nut closest to the hose. (spring with less hardness)
If you want the pedal backs up quicker to its initial position, let the adjustment nut further from the hose. (spring with more hardness)
-To do this, we loosen the nut’s allen screw and move the adjustment nut to one side or another. Finally back to tighten the allen screw.

Changing the Spring. Counter clockwise the bottom of the damper and remove
the spring.
RECOMMENDATION = For a more realistic touch braking, we recommend leaving the adjustment Nut closer to the hose. Thereby, the pedal backs up slower to its initial position. 3

6) Pressure Sensor Adjustment
The pressure sensor has internally the load cell, which automatically converts the sensor voltage to a value with a precision of 24 bits. So the simulator will read it automatically.
6.1) We turn clockwise the central screw ( with ALLEN WRENCH ) of the end of hydraulic tank to the maximum.
This will be the hardest point of the pressure sensor. (Minimum travel pedal and maximum force to make with the foot).
6.2) From that position, we can turn the screw 360 degrees counter clockwise, getting the minimum point of hardness pressure sensor (maximum travel pedal and minimum pedal force to make with the foot).
6.3) Find the optimal configuration by the user within 360 º turn of the allen screw.
IMPORTANT NOTE = Exceeding the 360 ° turn, the pressure sensor will not exercise its function. Return tighten the allen screw to the maximum (clockwise) and calibrate again.

RECOMMENDATION = For a more realistic touch braking, we recommend leaving the adjustment screw between 90 ° (¼ turn of the screw) and 270 ° (¾ turn the screw) degrees of turn. (From the maximum torque of screw) 4
