Default No back brakes "help"

I have bleed the system many times even the ABS module. I still can not get the back wheels to stop while its jacked up and in gear with the brakes applied. Please help, also the ABS in op and brake lights are on.

1994 firebird formula, I bleed the abs system then the rears then the fronts in correct order furthest then closest, keep in mind I did this multiple times too. I dont understand why the lights go off and on while im bleeding the abs system?

I mean, two person, gravity, vacuum, or what? Two man bleeding is still the best imo...

Two person and I used a hose on the bleeder valve and the hose into a bottle of brake fluid so the bleeder cant back flow any air. Its a fool proof method.

My question is: why are you bleeding the brakes? Did you replace something? What ever you replaced could be the source of the problem.

Manually bleed them. One person applies pressure, open bleed, allow pedal to go down about 3/4 travel, close valve, lift off of the pedal, and repeat... a lot.

Bleed order: RR, LR, RF and then LF. Not sure the order needs to be exact, but this seems to be the industry standard practice.

Bleeding brakes (to remove air) on an ABS car is the same as a non-ABS car. Just keep at it until you no longer get air bubbles from the bleeder.

Also, remember that if you get the bleed screw too loose, you could be sucking air in from the threads and then back out the main port... so make sure you just barley loosen the bleed screw.
