Soooo.... confession time. My Cutlass dash brake light came on one day in November 2021, no leaks or fluid loss, so I assumed the four year old "remanufactured" O'Reilly master cylinder (part #10-1738) had taken a crap. Replaced M/C, tried to bleed brakes but had no fluid coming from rear bleeder screws. My assumption at this point was that the combination valve was stuck off center. Proceeded to remove combination valve. Between cold weather (by my standards), lack of ambition, and rusty fittings on the valve, I finally removed it a couple of weeks ago. Installed new Inline Tube front and M/C lines, along with a CPP PV-2 combination valve, still nothing out back. Loosened fittings at M/C and realized there was no fluid coming from front port (rear brakes). Swapped basically new remanufactured M/C for another from O'Reilly, bench bled, installed. Again, nothing from front port. Am I just getting bad parts or having a brain fart and missing something in my process? Need to buy "new" M/C? Reminder, if it matters, that I have C6 calipers on the front and stock drums out back.
