105 Brake Issue

[steved]

I have a 1969 105 that was my Grandfather's that I'm getting back in service. The brakes are very tight. It appears that the brake lever is not rotating freely on the pivot pin. This model has the internal brakes. I've removed the brake adjusting screw but what else holds the lever pin in place? I've tried driving the pin out from both directions but it does not want to budge. PB blaster on all joints has helped somewhat with freeing up the brakes but still way to stiff and has definitely not helped with removing the pin. I've looked at the schematics but there does not appear to be anything to hold the pin in place. I'm posting a picture. Thanks for your help.

This is a little larger view. How to get the pin out of the brake lever?
Thanks for your help.

Just use plenty of pb blaster and be patient.

Just keep using brass rod and hammer? Does direction matter?
Thanks!

No it does not.

Lots of PB applied all over and over a few days.

If I had an air chisel with a pointed end and could put it on the end of the pin, I would rappatap it some to get it loosened.

IIRC, the pin is grooved, the adjusting bolt that you already took out fits in the groove to hold the pin in place.

There is A LOT of area inside that rockshaft for rust to accumulate, so it will take a lot of penetrating oil and a lot of time to break down all that rust.

Patience here is your best friend.

Don't forget to spray your PB Blaster in the bolt hole as well as the "joints".

Thanks, I was scared I was going to break something or was missing how it goes together. I'll work on it this weekend and let you know how it goes. Thanks again!

Thanks for everyone's help. The pin finally popped out and after clean up, I hope to get it back together tonight.
