Hi, I have a 2001 Ranger 4x4 with full anti-lock brakes. Most of the time, the brake pedal travel is long, and the brakes are weak, especially the rear. Even hard applications won't produce any heat on the rear drums, but the rotors get plenty hot. Sometimes, however, the pedal is higher and firmer, and I do get rear brake action and the drums do get hot. The wheel cylinders are free, and the shoes are properly adjusted. Could air in the system cause an intermittent problem like this? Also, does anyone here know how the front to rear proportioning valve works and if it is load sensing? The truck has been to the dealer five times but they can't fix it. They say it's working fine, but they are dead wrong. They claim to have bled the brakes four times, but I still suspect air in he system is the problem. Henry
