I've searched the forums to the best of my abilities, so please forgive me if there's already a thread about this. I just haven't found it. Ever since I bought my truck two months ago, I've had issues with the brakes. At first, only the last bit of pedal travel gave me stopping power. I'm talking the last two inches or so. I had just bought it and knew it'd need at least new pads and shoes. Did the brake job, replacing the pads, rotors, and shoes in the back along with a parking brake cable. The right rear shoe had eaten into the drum just a bit because it had been metal on metal for so long. I now had no vibrations or noise when braking. It sure felt like an improvement. But the pedal was still the same. It felt like it was pushing past a seal and figured it was probably the master cylinder. Then my ABS light came on. Read about the ABS light possibly occurring because of the rotor swap and the wheel speed sensor. Decided the master cylinder was the more important job to take care of. Replaced it and still the same pedal feel. Finally, the brakes completely went out in the middle of rush hour on the busiest road in town. Both the ABS and emergency brake lights were on. Managed to get over three lanes, fly into a parking lot, and pull the ABS fuses to get some brakes back. Replaced the ABS module, tapped the offending wheel speed sensor back into place with a 2x4, and bled the brakes both the old way and with a vacuum bleeder. Haven't had the ABS light come on since. My pedal now had pressure through the whole travel, but it was a bit spongy when the truck was on. When the engine wasn't running, the pedal got stiff quickly. Went to start it up recently, and the pedal goes straight to the floor immediately upon the engine starting. What's weird is that even with no brake pedal pressure, my brakes still work well. Any ideas? I'm relatively new to brake systems.
