no rear brake

[copteaser]

I replaced master cylinder,( yes I bled the master cylinder before the installation) new proportion valve, new brake lines, new rear disc brake kit. I can't seem to bleed the rear calipers, the front calipers are fine. I bled t hem with ease, but the rear calipers can't. I tried everything. I loosen the large line coming out of the proportioning valve, took off the cover to the master cylinder but only a few drops came out. Any ideas??

have you tried the bleeder valve on the rear ? One on each side . Brake it with a socket first then use a wrench

the rear end has a brand new disc convertion kit. I tried bleeding the calipers, (with the cover on the master cylinder off) I tried loosing the lines on the caliper and allow gravity to let some fluid out but only a few drops came out. I have a hydrobooster. can that be the problem?
