03 chevy the calipers (pretty much all 4)will not release. Tried replacing the brake lines, master cyl, still no luck. Disabled the abs removing the fuse and the problem is gone.
Before i replace the abs hydraulic unit, how else to find exactly what is not working. How to find if the problem is indeed the abs hydraulic unit or is the abs computer separate from the the hydraulic unit???

TIA

FWIW, i finally narrowed it down where the abs is the one that wont release. I removed the ABS fuse to disable abs and it didnt lock up again. I left it out for about a year then inspections were due so i plugged in the fuse to get the light to shut off and pass test.
i slacked on pulling out the fuse again for a while and another year later with the fuse still back in, it looks like the problem fixed itself after all....
