Calliper holder pin seized

(1/3) > >>

Athame57:
I dismantled the front brake callipers on my CB400F2 this morning after noticing the calliper holder wasn't being effected by the spring that is supposed to position it, that hasn't actually stopped the brakes working so it may have been like that for years even. My problem is the pin is so seized I'm wondering what to do, I've already caused some Sunday morning complaints with my efforts to release it. I've also damaged a park bench downstairs using the slats for a vice, I don't have the luxury of a workshop. I end up going on the CMSL diagram to make sure there is a pin going through there. Any suggestions? 

Trigger:
Take it to a engineering shop and they will heat it to get it apart. The pin doesn't get worn too much, it is always the bushes in the arm.  ;)

Thanks Graham, I'm going to take that advice. I've just bent a large screwdriver I was using for leverage. The pin did move with a lot of noise for a part turn, but I think it is time to give up trying to do this myself!  ::)

Trigger:
You need the right tools  ;)
I had a couple of 750 here a couple of weeks ago and they would not budge even with heat. If that happens it is time to drill the pin out  :o

If you have some movement in the pin you should be able to get some releasing oil in there and keep loosening it. Let it soak for a while and then keep wiggling it back and forth. The movement should gradually improve until it comes out. It's not easy without a bench or a vice but worth a go.
Have you got space for a Workmate portable folding bench/vice? Very useful if you haven't got anything else.
