1981 C-10 Brake Pedal Problem - Need Advice

[MirandaB]

I was driving my 1981 C-10 the other day and noticed that the brake pedal wasn't returning all the way to its proper position when I took my foot off it. I parked it until the weather would permit me to work on it. Today it is clear and in the 40s (truck is outside and I don't have any garage to work in) so I tried to figure out what the problem is, but no dice.

I first thought that the pedal sticking might be related to the new(er) steering column I installed this past summer, so I removed both the lower dash panel under the steering column and the instrument bezel to get a better view. I can't see anything amiss with the installation, and no binding of any of the wiring in way of the pedal and surrounding metalwork. In fact, I can't even see anything that is supposed to pull the pedal back to position, like a spring or something.

I looked through my Haynes manual but there weren't any diagrams of the brake pedal mechanism, so I am SOL there as well.

Before I remove the instrument cluster to get an even better view of the top of the area over the pedal, can anyone shed some light on this for me?

Thanks,

Miranda
