I've done the intro post, now onto the ? post.
My first problem, the brakes are spongy, they stop the truck but the pedal is nearly to the floor. Releasing the pedal, it never "springs back" enough to shut off the brake lights. I must us my foot to bring the pedal back up. Any thoughts?

 

Master cylinder is trashed

 

Thanks for the info.

 

I'd check the master cylinder first. Make sure you bleed the sytem well though as the spongy part may be air in the system.I've also had wheel cylinders, failed brake boosters and rotten flex hoses do similar things but the master cylinder is the most common after air in the system. With it not returning, I'd say it's the mster cylinder.
