Title: Brake problems Post by cFLOW on 03/28/07 at 15:52:24 Hey guys I recently had to remove the the brake caliper. I drained the fluid,went to put everything back together and I have no pressure at all. Very little fluid coming out of the bleeder valve. I am thinking it may be the the MC but not sure what do you guys think I should do. do you guys think a bleeder kit would help with the problem. Thanks |

Title: Re: Brake problems Post by vroom1776 on 03/28/07 at 15:58:05 did the brake fluid level in the MC drop too low (i.e. below the small hole at the bottom of the resevoir)? If so, you need to bleed the brakes (you prolly do anyway). In my opinion, brake bleeding kits only help to draw most of the brake fluid down tot he caliper, but not in removing air from the lines... |

Title: Re: Brake problems Post by vroom1776 on 03/28/07 at 16:49:02 okay... you drained all the brake fluid? close up the bleed valve at the caliper. open the MC and have a bottle of brake fluid handy... make sure the union bolts are are on there good and tight (not over tight, of course). start pumping the brake lever. you should occasionally see air bubbles coming up from the bottom of the MC. Keep doing this. for a long time. you will not get any pressure for quite a while. Whenever the MC gets low, add more fluid. DO NOT let the level of fluid go down to the little hole... after a while, the air bubbles will stop coming up... now you can bleed the brake at the caliper. You can leave the bleed valve at the caliper closed b/c as you actuate the brake lever, it will force brake fluid down there and the air bubles, being less dense, will rise. It MAY be quicker to leave the blled valve open and just keep pouring brake fluid intot he MC and ground (i.e. out the bleed valve), but most likely air will keep slipping in through the valve.... ALSO, you are using eitehr DOT4 or 3 bake fluid, right? Not 5? 5 will eat the brake lines, I think. Also, don't mix the different spec fluids... If you've done this, you need to flush the whole system... sice you've taken all the fluid out of the lines, a mighty vac kit would definitely be a time save instead of just pumping away at the lever... |

Title: Re: Brake problems Post by georgekathe on 03/28/07 at 20:22:34 Re last entry - I seem to recall others posting on site found might vac kit not good/did not work to bleed brakes - clarification, anyone? I used the old tube on the bleed valve going into a jar of fluid way when changing fluid/bleeding brakes & it worked fine. |

Title: Re: Brake problems Post by verslagen1 on 03/28/07 at 21:20:18 i found speed bleeders on ebay. they replace the stock bleeders. they have teflon coating on threads, and a spring loaded ball check valve. when loose, the check valve works, when tite, the bleeder is shut off just like the stock bleeders. I have all my parts now and will give it a try soon. |

Title: Re: Brake problems Post by vroom1776 on 03/29/07 at 00:14:37 I have a migthy vac kit... I only like it for pulling fluid down to the caliper, not for bleeding (i.e. getting the last bit of air out) |

I thought it pulled the fluid way too fast for the amount in this bike. It'll dang sure drain it quick when you're changing the brake line though. |

Title: Re: Brake problems Post by Reelthing on 03/29/07 at 06:52:18 picked up a big syringe(2 oz) from the drug store for fifty cents - the hose that I use on the bleeder fits over the end - works real fine to pull the initial fluid down the line and keep a little vac on it during bleeding http://reelthing.savageriders.com/pics/savage/sucker.jpg |

Title: Re: Brake problems Post by Savage_Rob on 03/29/07 at 09:51:52 Yeah, they have a kit like that for about $2 at Harbor Freight. |
