Hey,

I have a 1979 ford f150 2wd 351m. I have parcel front brakes and no rear brakes i have put new spring for the brakes in the rear and put in a new mc. i can bleed the brakes and the front and back brakes work for about 3 or 4 stops the back brakes seem to go out slowly during the braking then completely go out and only parcel front after them 3 or 4 stops. it seems not to be losing brake fluid. it just started to do this when i was driving it one day. I was hoping some one could help me

Thanks,
Fordman_95
