Adjusting brakes
I am having a very hard time adjusting my rear brakes.
I have a mountain bike. Low end. :-) If I adjust it to where it grabs the rim tightly, it slows my bike down due to the resistance from the brake touching the rim. It's very frustrating. Thanks, Andy |

Thanks, Andy First off, does your rim run straight without dents ? Any bearing slop? Secondly are there kinks or other impedimanta to your cable? Do your brake pads meet the rim squarely and fully or are they askew? Is everything original? Mismatch of standard lever with long pull linear brake would give that symptom. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

What type of brake, type of brake lever, etc? A link to some photos would help. -- - Frank Krygowski |

I have yet to see that on any well-ridden mountain bike, at least after the first 100 miles :-) Which is why I've always used steel rims. Aluminium can buckle so badly that you only have one spoke to 'attempt' to straighten it, where as with steel, there s usually four spoke you can fiddle with to reduce the wobble. [...] |

It would be nice if I could get 29er steel rims. But it's ok, I do not mind wheels slightly out of true. Even my road bike gets rim dings every now and then. I true them out only when I feel like it (and that's not very often). -- Regards, Joerg http://www.analogconsultants.com/ |

Fix those. The portion of cable visible in those photos looks extra long. You may have similar extra length at brake lever end. Sometimes that can cause some extra lost motion. Whether or not you correct that by shortening the cable and housing, you might try lubricating your cables. Are your brake levers adjustable for reach? Some are. Try that adjustment. Those brakes themselves are pretty foolproof. -- - Frank Krygowski |
