I agree with Rick. The rears have to be adjusted for the system to work well=
. You need to adjust them so there is a little drag, drive it a little with s=
ome hard stops, and adjust it again.=20

The first press of the pedal moves the shoes away from their resting posit=
ion, but not all the way to the drum. A quick second press of the pedal mo=
ves them even further. A quick third press of the pedal may put the shoes i=
n contact with the drum and the pedal feels hard. Release the pedal and the=
shoes move all the way back to their initial resting position and you start=
all over again when you want to use the brakes. No air in the system and t=
he pedal feels great once you get the shoes all the way out to the drum.

Ok. I guess hard is a relative term. Assuming I'm wrong, and there is no a=
ir in the system what is causing the pedal to need to pump up?

If there is air in the system then the pedal will feel 'springy' or 'bounc=

The old one was 7/8" in one bore for the drum brakes and 3/4" bore for th=
