89 4dr ef non abs.........i just changed the MC , pads and rotors....because the pedal was going to the floor ...but after all that it is still going to the floor....is it the break booster not holding or what ?

 

probably just some air in the lines. Try bleeding again. The brake booster is probably fine.

 

well like an idot i forgot to bleed the bake brakes.... then while trying to bleed them i broke the bleeder valve...so now its time for rear disk converstion!!

 

That suckz man. The peddle problem can also come from the vacuum line at the booster being cracked or otherwise unhealthy.

Just something else to watch out for.
