3. Makes sure the squeak is no longer present by pressing and releasing the pedal.

4. Brake pedal: Depress the brake pedal. Pull out the pushrod (green connector) and apply 30 25 368 Low temperature paste . Release the pedal and pull back so that the pushrod on the pedal switch takes its correct position.
