yea that is right the drums have a different valve,that keeps the shoes close to the drum, the front have a valve that keep light pressure in the pads at all times,that is why serious drag racers prefer drums all the way around,so there is no drag, disc brakes always have some pressure on the pad but not so much it stops the wheel, i think there is a problem with the prop. valve
,but it is just a valve so if dirt is trapped in there the fluid will not flow back as easily,
this is kinda baffeling but brakes are simple but if there is air or dirt in the line there will be problems
,you know the calipers are good, the master cylinder is good,
man it has the be that valve,or something in the line that didnt get blown out,
yea a real head scratcher
