Hello. I just joined to thank this website and to share success and hiccup from a thread I found here.
I have a 96 K1500 that doesn’t drive much but is still on work duty. It has suffered from soft brakes and low brake pedal probably for over 10 years after I changed the brake master cylinder. Everything is stock replacement parts.
Fast forward. The booster started hissing while held down so I replaced it. Couldn’t bleed the brakes and suspected I had air from not re bench bleeding the master during booster change. Very little fluid would come out of rear wheel cylinders. Replaced the master cylinder again. Still couldn’t get air out and the pedal is even lower. Too low to be safe. And the service brake light was hard to stay off. Sometimes it would come on while pumping. Sometimes it would turn off while pumping, both during bleeding.
Suspected abs auto bleed and ordered a Foxwell NT630 Plus off amazon. Doesn’t look like it can do the auto bleed on 96 that I’ve seen work on newer trucks. Returned.
Found this thread here. On relieving pressure at the ABS module.
Pressed the button/pin in under the rubber cap on the fender side of the abs module and rebled. Got way more air out the rear wheel cylinders. Pedal hasn’t been this firm in 10years.
Thank you.

98 gmc yukon brakes help! I've done everything
Swapped a 14 bolt sf in the rear. I had spongy brakes before the swap but figured I'd deal with that after the swap was complete. I decided to put discs in the rear from lugnut4x4.com. bled the crap out of everything and still spongy. Call a brake shop who advises a master cylinder made for 4...
