97 K1500 W/Kelsey-Hayes ABS- A few days ago the brake pedal went extra low and on came the brake light. Still able to stop but extremely low pedal. Fluid level was perfect. Bled brakes starting at right rear using 2 person method. No change. Replaced master cylinder - bench bled and bled brakes. No change. Took it to a shop and had a pressurized brake flush done, still no change. Found some article on bleeding the ABS module. Started with pushing the little nipple on the ABS to purge the fluid. No change. Drove down the road and locked up brakes to make ABS kick in. Tried bleeding after that. Nothing. Replaced rear soft hose(fronts are pretty new and there is no pulling issue) and now it gets weird
First time cracking the bleeder the fluid shoots out in a nice stream with a lot of air. 2nd time cracking the bleeder there's barely any pressure and the fluid just trickles out. Somewhere along the line I noticed that if I held the pedal, cracked the bleeder. closed the bleeder, let off the pedal, started the truck, mashed/let off the pedal, killed the truck, held the pedal and cracked the bleeder again, well then I got my normal pressure at the wheel and a lot of air. So I did this about 20 times. Still no change. What am I missing/overlooking??
