on my 99x1, the reservore line got a hole rubed in it. so i replaced it, and now i cannot absolutely not get any pedal... i have tried conventional bleeding, pumping pedal, holding opening bleeder, close bleeder and repeat method.. i have tried opening the bleeder and letting it gravity bleed... i have tried using a mighty vac vacuum bleeder, no luck... now today i tried using a medicinal syringe and peice of hose, and pushing brake fluid from the bleeder to the reservore.... and that worked the best, but it wouldnt push all the way to the reservore, it would build huge amounts of pressure in the syringe, but nothings coming up to the reservore..?>> but it would give me a decent pedal for about 45 seconds... then by the time i got the seat put back on, i had lost all pedal feel. did this twice. sooooo..... any ideas? something clogging the master cylinder? im sure im gonna have to order a master cylinder rebuild kit, but just looking for some insight... |

Could be time for a master cylinder rebuild. 45073-98Y, $12.50 list. Depending on how long it went without fluid, you could have torn a seal in there somewhere... |

I'm betting it's bled fine, and that the piston in the caliper is over-retracting. The first fix would be pumping out the piston aways (Hold it gently with pliars and pump the MC), cleaning it with a good brake cleaner and an old toothbrush, and pushing it in again. |

I had a similar problem with the front. Rebuilt the caliper and master cylinder. Works great know. Tricky thing with rear is the hose has a high spot to collect air and unless you bleed it fast enough you won't be able to chase it out. Try bleeding off the bike first with the hose at the low point. |

DNChevyman, take a screwdriver and push your calipar pistons in and then start pumping slowly. DO NOT push the pedal all the way down!!! Just go about half way. When you push the pistons in, you force the air bubbles and fluid back into the master cylinder. This moves the MC piston back if its sticking and clean out anything stuck in their. Good Luck and check for crap in the MC res. before pumping!!! |

the last time i did my s2 rear brake it wouldn't bleed until i removed the caliper and raised it to seat height for the bleeding. after2-3 hours of messing with it mounted on the disc-it bled all the air out and worked properly after about 5 minutes with it held higher than everything else in the system. make sure that you put something of disc thickness between the pads. good luck. tim |

Let me know what works, I just used a mity vac on a 99 x-1, and I have a totally dead pedal. I don't mean mushy, I mean the pedal flops lit it isnt connected. |

OK, rebuilt the rear master on the X1. When I took the master apart, the plunger was stuck at the top. Couldn't reverse bleed either. Rebuild kit < $15. Then I bled with the vac bleeder, bled right up to s nice stiff pedal. Never had a piston freeze closed, but that was why it wouldn't bleed. |

Another thing to check and found this out the hard way, check to make sure banjo bolts at both ends are tight. I was having problems again, even with a vac and it came down to checking those and found they were just loose enough to suck in air. Sometimes it's the easiest and most overlooked things that'll get you. |
