rear break problem
Hi.
Dont know what went wrong but trying to fix it.
The cable seems slack, so I tighten it, then pull the brake and it wont move back and the cable goes slack again?? I have tried everything but don't understand how to fix it :?:
Thanks.

slack inner clamp bolt?
dirty cables?"Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

Sticking calliper? Have dismantled, cleaned and lubed both of mine today.0

The bolt going through the middle of the calliper can be adjusted to tighten/loosen the movement of the calliper. Usually a small grub screw on one arm.I've added a signature to prove it is still possible.0

I don't understand, I think I might have to take it to a bike shop, will they all charge for doing this?0

Assuming this issue is on the Genesis with Tiagra callipers you need to view the exploded diagram of the calliper from Shimano here There are two things you need to undo to slacken off the calliper slightly, the grub screw in the floating arm and the nut (4), you should only have to undo nut (4) by 1/8 turn. You sholud be able to squeeze the calliper by hand quite easily in the palm of your hand and it will return to open if loose enough. You might have to fine tune the adjustment if thers is too much lateral movement of the calliper but this you'll only find when mounted back in the frame.I've added a signature to prove it is still possible.0

Probably a combination of dirty cables and corroded pivots in the brake caliper. Unclamp the cable and see if you can flush-out the cable outer with some WD40/GT85 - slide the cable inner back and forth to get it running smoothly. Wipe off the spray and apply chain lube to the inner cable. Remove the caliper and push the arms together - do they spring back unaided? If not, then you probably need to service / dismantle the brake caliper - cheaper calipers often use plain bushings which can corrode - clean up all rotating/swivelling faces with emery paper / steel wool, grease all moving faces and reassemble. You'll probably need to use Loctite to hold some of the screws in position. I doubt your LBS would do the job - it's fiddly and time consuming - they'll probably try and sell you some new brakes.Make mine an Italian, with Campagnolo on the side..0
