I agree with Bill about bleeding the master on the bench first. As an auto mechanic for 45 years I have done more than my fair share of brake jobs, and bleeding the air out is sometimes a problem. As bill says, get the cylinder level, not the reservoir, then attach a fitting with a hose looped up into the reservoir. fill it half way with brake fluid and make sure the end of the hose is in the fluid. Slowly pull the lever in and out until all the bubbles are out of the cylinder. Disconnect the fitting at the cylinder, plug it with something, duct tape will work, so as to not leak too much fluid out. Stick your master back on the bars, connect the line to your caliper, and then bleed in the normal way, using a jar or bottle with some fluid in. Most guys have problems with air in the master cylinder and this should help with that.
