1975 CB500 K1 rear brake pedal arm position
« on: April 05, 2024, 11:17:41 AM »
As it was already in bits, I didnt get to see how fitted.

In the Haynes manual says to put arm in front of swinging arm and also shows return spring on inside of frame.

It does not work like this and lever binds up with actuator rod end.

Honda manual has a picture that shows arm behind swinging arm and outside spring.

Im guessing that Honda changed before end of K1 production?

Will now try re positioning

The return spring on my 500 K1 was missing. I eventually sourced the correct return spring for my 500 the spring sits on the outside of the frame/swing arm as you have identified.

There is a photo by Simon (SPR) showing it fitted.

All i say is the first thing to fit to the bare frame is therear brake actuator arm, and yes the spring goes on outside
