Question about 1990 Chevrolet Lumina APV
If the pedal is going to the floor while you are trying to stop and not pumping back up, you could have a few conditions that would cause this.... master cylinder may be faulty, rear wheel cylinders could be blown out and leaking, front caliper(s) could be leaking. Or a brake hose could be leaking.... check at the back of the master cylinder where it bolts to the brake booster, look for signs of brake fluid where they meet, that is usually a good indication that the master cylinder is leaking past the seals and could be causing your problem. Hope this helps.
