Master Cylinder problem?

i drive a 1984 toyota pickup. its a dlx so its extended cab and such. my problem is my brakes. i just did a 4 wheel brake job and i still have a low pedal and only my front brakes work. It also leaks brake fluid, i have to fill it every couple of hours. its getting annoying so im wondering if its my master cylinder thats broke?

can you tell where the fluid is leaking?
after doing the brakes, did you bleed all 4 wheels then the LSPV (the load sensing proportioning valve above the rear axle)?

X2 where? That is a pretty big leak. Is it leaking constantly or just under pressure?

Did the brakes work before?

Leaks brake fluid where? Out the tailpipe?

What was your bleeding procedure?

bled all four brakes, did not bleed load proportioning valve, and i believe its leaking out of the back passenger side wheel cylinder because it was bad, but it leaks under load or not...if i fill it and park it, it will be empty by morning...i should have it fixed soon because i went to NAPA yesterday and ordered wheel cylinder and master cylinder, if that dont work then im jumping that P.O.S
