1996 Nissan Maxima SE 6Cyl3.0L - Brakes
I replaced the master cylinder because the brake pedal would go almost to the floor .I also bled the brakes.
It still seems to be doing the same thing. I just bled the brakes again and it hasn't changed any. What I have noticed is that neither rear caliper is working when the brakes are applied. Is there some proportioning valve not working possiblly? Also the abs light stays on all the time. Thank you!

    A professional has to attempt to bleed this brake system I believe. Proportioning valves rarely fail, you did not need a new master cylinder. Can you be certain that there are no rusted through brake lines leaking when you pump up the pedal?
