Hi need a bit of help with my NC23 , it an 89 RRK and I'm having trouble with the rear brake , I have recently stripped down cleaned and rebuilt the rear caliber but I now find that I cannot bleed the brake. I have brake fluid flowing from the reserve to the master cyclinder but it doesn't pass through it along the brake line to the rear caliber, what should I do now , is it hard to strip the master cylinder , I've tried a couple of times to get the air out incase the fluid was full of air bubbles , I then drained the system and put in another bottle of new brake fluid , let it settle for a few hours to no avail what can I do now ? Help needed

Presure bleeder will do this or crack on as you have been, bit at a time and it will come through...

Put a clear peice of tubing over nipple.crack it of and suck....as the fluid goes down in res close nipple while still sucking.refill res.suck on pipe as you crack open nipple.will bleed in seconds.as long as fluid is drawn through..

Another option is to fill from the caliper using a syringe and tubing over the nipple but watch the reservoir does not overspill, empty as needed.
