Installation
Measure the height of the pedal to the floor. See required value Here.
If the measured value of the pedal height differs from the specified one, have it and the pedal travel adjusted by a specialist workshop.
Screw in the brake light switch until it touches the pedal stop. Screw on without tightening the locknut.
