In my car, I replaced all the brake lines, because there was very very little brake power and because all the lines were dry in the wheel wells, I thought they had collapsed (23 yr old car). Anyway, did all that, and now I don't have front brakes. When I have someone help me bleed all the brakes, the rears work fine, the pedal drops to the floor when I open the bleeder bolt. The pedal doesn't move at all when I open up the front bleeder bolts. It stays at about halfway, The calipers will move in the front when the pedal is pushed, but the brakes don't stop the car at all.

I tried bleeding the master cylinder today, that was no help. The lines aren't leaking anywhere.

When I sit in the car and pump the brake pedal, the pedal never gets stiffer like it does in my Cavalier.

I used a bleeder tool for the front brakes, but it couldn't create a vacuum like in the rear brakes.

I can hear sloshing in the reservoir when I push the brake pedal. I don't think that's normal.

Please help! I think I need to replace the Master Cylinder but I don't want to unless I'm sure about it.

Also, there's no ABS.

I think your metering valve is bad, this applies to vehicle with front disc rear drums, your front pads are always in very close contact with the rotors, but the shoes are pulled away when the pedal is released, if the front applies before the rears your car will go into a tailspin, a metering valve prevents them, it allows fluid to the rears, but not to the front until a certain pressure is reached.

If the metering valve is stuck it will never allow fluid to the front

This is actually for a car with rear disc brakes if that matters. It's not a Jbody. It's my Fiero.

Oh well nevermind, 4 wheel disc dont have a metering valve, in that case I would say its the master cylinder
