Frequently Asked Questions

What thread does Honda hydraulic brake switch 35350-300-006 use?

The switch uses an M10 x 1.25 thread and replaces Honda OEM 35350-300-006 and 35350-300-016.

How does a hydraulic stop-light switch operate?

Brake-system pressure closes its electrical contacts to illuminate the brake light. It is not a mechanical lever- or pedal-operated switch.

What must be checked after installing the hydraulic switch?

Use the correct sealing method and torque, bleed the brake system if the hydraulic circuit was opened, hold firm pressure while checking for leaks and confirm the brake light turns on and off correctly.
