Hey Guys,
I had a soft brake pedal that felt like it wanted to go to the floor. I decided to try and replace the dirty brake fluid. The truck is new to me so I need to inspect the shoes and pads as well. I started by removing most of the dirty fluid from the master cylinder, replacing it with clean fluid, and bleeding starting at the right rear wheel (drum). I noticed right away that my bleeder wouldn't hold steady pressure with the bleed screw closed. I tested the bleeder on all 3 other wheels, pumped it up to 10-12lbs, and it held steady like I would expect. I figured the bleed screw was bad, but after a quick replacement it still leaked down pretty quickly. I don't see any visible signs of leakage (yet).
My next stop will be to replace the wheel cylinder. I'm thinking that may have been the cause of my spongy pedal in the first place. I've also learned through web searches about the Automated Bleeding procedure using the ODB programmer, which is on it's way via Amazon.
Am I on the right path? Any other advice or tips will be appreciated.
