those vacuum pumps are a joke.
you need to get a helper in there.

heres what i would do

clamp the three brake hoses. one on the rear axle and two on each caliper. use specified brake hose clamps or needle nose vice grips. (not too tight)

what you are doing is isolating the trouble area.

push down the pedal.
if the problem is downstream of the clamps, the pedal should be rock solid.

if its a wet noodle, keep the clamps on. have a helper operate the pedal.
crack the line on the master. have helper push down and hold. tighten fitting. do this to all fittings on master.repeat 2x.
check fluid level. if pedal is still soft, have helper pump slowly three times and hold pedal. open fitting. close fitting. repeat 2x on all fittings.

check fluid. if by this time pedal is soft, you have a defective master. i dont care if its new or reman. remans are especially junk. you will have best results from OEM parts.

onto if the pedal is rock solid.

take off one clamp only. check pedal.
when the pedal goes down, you found the trouble area.
bleed in the same manner as above.

your rear drum brakes wont make up much of a differnce for this test. most of what you will feel will come from the calipers.


since i probly will forget about checking back here, if you need help, PM me.
