More recently I've noticed that when I press on the brake pedal there's an anoying squeak like the sound of rubber on rubber. I know it has to be coming from where the brake pedal meets rubber but wondering how to fix it? Thoughts?

 

mine squeeked at the pivot bushing ,I used tri flow lub on it, gone.

 

Is that a bushing which attaches the brake pedal to the truck under the dash? Thanks!
