Also finished fitting them to the bike, but left the job of bleeding them until today. I was a little apprehensive of this. From previous experience I know a completely dry system can be a pig to sort out, plus the fact I've heard mixed reviews about the repro master cylinder I was using.
So being 'brave' I started with the rear end, (Jimmock, don't even go there!) that went well. Apart from completely rebuilding the caliper I completely stripped the master cylinder to clean out all the crystallised brake fluid. It all bled up a treat.
Next was the front end. I filled the master reservoir & gave the lever a few pumps......... Nothing, which was to be expected. I started to pull the fluid down into the system with a vacuum bleeder (Mityvac), after doing both calipers a couple of times, there was only clear fluid coming through, not a bubble in sight, however there was still absolutely no pressure at the lever. I thought I might be suffering the same 'curse' as Ralph. I tied the lever back to the bar & found something else to do for a couple of hours, being able to resist temptation no longer, I released the lever & after a couple of pumps, there was now some pressure at the lever. I retied the lever & tried again after another couple of hours, the result got better every time, by the time I vacated the garage, I had a good firm front brake.
