Thanks for your reply.

Tony, the brake light bulbs have been changed twice before we got the vehicle, we have checked them and they seem OK..

Steve, can you expand on the comment regarding the double action of releasing the rachet system?

we have fitted the switch with the pedal depressed, locked the switch into position and released the pedal.. from that you can hear the switch self adjusting.. is there another procedure?

Regards
Kris
