Front brake on my 78k still dragging some even after caliper rebuild. Was told by good mechanic that fluid should squirt back into the master cylinder reservoir with apply and release of brake thru the two ports. It does on squeeze of lever on the inside hole but nothing on release. Took small wire and it went in far enough to apparently bottom out on something. Piston? Not sure what’s in there. Any comments appreciated.
