Gandalf's KZ400 repair thread

[Gandalf]

I hope you admins don't mind me creating two separate threads, but since they're two separate simultaneous projects it seemed to make the most sense.

Anyway, I'm working on a 1975 KZ400, running condition as of right now unknown, but it looks really nice. 9k miles, chrome is almost perfect, paint is slightly faded. Pic is below, sorry for the quality.




First question: Rear brake drum was locked when I got the bike...I disconnected the linkage and the drum works perfectly, but the brake pedal pivot point is seized. It takes a TON of force to move it up or down. I've sprayed it with PB Blaster, removed the nut and washers holding it to the frame, and spend a considerable amount of time both rotating it and attempting to pry it free from the frame. It will turn, but no amount of effort pulls it away from the frame. Any suggestions? Normally I'd just heat it up and see if that helped but I don't want to mar the chrome.
