Weinmann 730 brakes and that pesky plastic bit at the front.
Hello,
My bike has Weinmann 730 brakes fitted to it. Yesterday, one of the leavers sheered off. So I go down the shop and get a replacement. As it turned out, the section which goes thought the forks it too short. No matter, I think, as I can use the old one, but I cannot get it out. As a matter of curiosity, does anyone know what the plastic bit at the front is for? It appears to twist round and not do anything. It surrounds a 4mm hexagonal nut or what appears to be a nut. Any ideas gratefully accepted. Cheers Peter. |

You can just slide it off (use pliers to grip if it's tight). Underneath is an adjustment nut and its locknut. Can't you unbolt it from th back of the fork? ISTR that's where they attach. |

Any ideas gratefully accepted. The plastic bit is just a cover. Pull it off (pliers if necc), and there are two 10mm nuts underneath. The 4mm bit is part of the pivot, onto which the 10mm nuts fit, and is designed to allow you to centre the brake (assuming you have the - quite unique! - tool). Removing the nuts will allow you to remove the pivot bolt from the brake assembly. HTH |

A well-stocked local bike shop should still sell these. Incidentally, the more expensive brakes had alloy spindles where this allen key will round off almost immediately if you use the tool; I replaced them with steel ones from another brakeset. The sheer crappiness of them makes you thankful for modern Shimano brakes, despite the extra weight of dual-pivot calipers. Disassembling the brake is straightforward using small ring spanners. |

Thank you for all the replies. I'm now a bit of a Weinman expert/bore
(delete as appropriate). I now realise that the section which goes through the forks was short because it goes through the rear forks which are not as thick as the front. I'm now sorted and have two brakes! Cheers Peter. "Peter Goddard" wrote in message ... Hello, My bike has Weinmann 730 brakes fitted to it. Yesterday, one of the leavers sheered off.
