Brake Problems...need Help Bad!!!

[mj1220mj]

I changed the master cylinder on my 90 accord without abs. I tried to bleed all the wheels. All the wheels sucessfull bled, except the front driver side. The caliper wasnt squeezing together. Put a new caliper on. Still not squeezing. Examined all the lines from the master cylinder to the front driver side caliper no kinks. But no fluid will come out of the bleed screw on the caliper. Tried slamming on the brakes, still nothing! Have no brake pedal, goes straight to the floor. Anyone else have this problem? Could it be the proportioning valve? Any help would be FU#$*% Great!!!

O yea the fluid comes out both places on the master cylinder when you pump the brakes. So I know its not the master cylinder. Thought that would help! Please any help would be great!!!

try replacing the rubber brake hose...it might be breaking apart inside causing a clog...if it is an original part I would definetly try this...or your proportioning valve could be going bad...but I would try the brake line first....I think you can get them for like 25 bucks....good luck.
