Brakes problem
1979 Chevy El Camino V8 Two Wheel Drive Automatic 83000 miles

Front brakes don't work very well. Rear brakes are fine. New calipers, new hoses, new pads, new master cylinder, new rear shoes, springs and hoses, flushed lines with new fluid twice. Removed proportioning valve for cleaning, flushed each steel line, no vacuum leak, seems as though booster is working. When backing on loose gravel front brakes will not lock-up. On normal stop rear brakes seem to do all the stopping, as car does not dive downward on hard braking, car stays level. Is there a way to check these proportioning valves?

Do you
have the same problem?

Your first mistake was taking the proportioning valve apart to clean it. That is a part that doens' tgo bad very often at all. I would take it back apart again and make sure it is together correctly. Or change it to a known good one alltogether. Then rebleed your system starting at the back right rear-left rear-right front-left front. My bet is you still have air in the system someplace. Apower brake bleeder would be your best bet.
