I have a 98 blackbird cbr 1100. It was a theft recovery. I've been riding it no problems for couple months. My only Transpo at moment.

The brakes are not linked. Matter of fact the back brakes are not in use at all and the caliper are not for the bikem. So I've been relying on front.

The other day I'm riding and get to an intersection, pull the brake lever...and nothing. Absolutely nothing.

Trailer bike home. I cannot find any leak whatsoever. Still have fluid in res. I take off line to resevior , place my finger over the hole and pull lever 2 or 3 times and get lots of pressure where can't hold finger over hole. Yet, with line attached I can pump 50 times..never build pressure ...never loose fluid.

I'm lost

 

If I remember correctly their is a second master cylinder for the linked system, is this fully disconnected? It is quite a complex system and their are a lot of pipes / valves etc as you can see from this link.

You might have an air leak there which of course you would not notice if you are going directly to the main reservoir.
Just a thought.

 

Im a great parts changer and mechaniic and getting much better.....but after careful consideration I've decidded that I'm not going to test my abilities on such item as brakes. There is a big difference in

A. I screwed up now the bike doesn't run and

B. I screwed up and now I'm hitting a wall at 70mph.

At 50 I'm not to keen on B

Taking to a Honda dealer seems a logical choice.

 

OK, do as you wish. A word to the wise though. If your breaks are not linked as they were from the factory, my prediction is that they're going to want to make that right. Dealers are money making machines. There are plenty of videos on YouTube that can show you all you wanted to know about repairing breaks on motorcycles. The principals of hydraulics is not rocket science. Mostly seals and get rid off the air because it's compressible. Now given that it's your only mode of transportation, that makes the decision tougher for sure. Good luck either way.

 

Can't disagree with your logic. If you are going to take it to a dealer be really clear on what you want them to do or as 'Idodirt' has stated you could be heading for a really big bill!
