1968 F500 has been parked for eight or twelve years

[dolinick]

I just got the truck running. It was a sheared roll pin I guess.

Oh I noticed the front of the driver rear leaf springs are not supporting
the truck as high as the passenger side. A broken spring mount or something.
I don't know yet.

However the truck has been parked probably since 2012 and i opened the master
cylinder reservoir and could feel just some dry pile of what i think is rust.

I'm thinking that the master cylinder among other things needs to be removed
and all the brake lines flushed out. Assuming the brake lines themselves are
actually still good.

The brake vacuum booster is under the frame behind the cab on this truck.
