Frequently Asked Questions
Which Honda rear brake-light spring does this replace?
It replaces Honda OEM 35357-046-000 on the 1975-1976 Honda CB400F rear brake-light switch linkage.
How many rear brake-light switch springs are included?
One spring is included, which is the quantity used between the rear brake pedal linkage and brake-light switch on one CB400F.
How should the rear brake-light switch be adjusted after installation?
Adjust it so the brake light comes on just before the rear brake begins to apply and turns fully off when the pedal returns. Confirm the spring does not bind or remain stretched through the pedal's full movement.
