ian Posted June 5, 2005 Report Share Posted June 5, 2005 hi i fitted my hope mono mini onto my forks etc and put everything on like the disc etc no dirt under the disk to it runs perfect. when i put the wheel in the disk seems to rub when just riding along. it seems to be catching on the pads is there nay way of moving them out or something to stop them rubbing or is it just because they are new pads. but the wierd thing is if i pull the lever slightly there is no rubbing at all. anyone know what could be wrong? thanks in advance. ian Quote Link to comment Share on other sites More sharing options...
Mr Motivator Posted June 5, 2005 Report Share Posted June 5, 2005 1st, check the rotor to see if its bent. If it is then use an udjustable spanner to bend it back. Then loosen off all the calliper bolts and pull the lever. Whilst still gripping the lever, do them all back up again tight. Should be fine then.

ian Posted June 5, 2005 Author Report Share Posted June 5, 2005 ok will go try that but i have tried it once. and it had no effect will edit when tried. Quote Link to comment Share on other sites More sharing options...
Luke Rainbird Posted June 5, 2005 Report Share Posted June 5, 2005 Mine does virtually the same, and I'm not entirely sure why. May just be worth checking that the pistons are nicely lubed to ensure that they are moving back freely, otherwise I'm not really sure what to suggest mate Quote Link to comment Share on other sites More sharing options...
nb88 Posted June 5, 2005 Report Share Posted June 5, 2005 Make sure the pistons arent sticking out at all - if they are, take the pads off and push them back gently with a tyre lever (not a screwdriver as you risk damaging it). Also if the caliper is rubbing on one side it may be off centre, use the shims supplied to adjust this by putting them between the mount and the caliper. This means you can only move it one way obviously. Quote Link to comment Share on other sites More sharing options...
iatola says Posted June 6, 2005 Report Share Posted June 6, 2005 To move the other way you need a very fancy tool from hope. The mount facing tool remove off paint or metla to give a straight clean surface and you can take as much off as you need. Not owrth buying one for just one use though about £80 i think. Local bike shop might have one Trev Quote Link to comment Share on other sites More sharing options...
Towler Posted June 6, 2005 Report Share Posted June 6, 2005 Adjust the spacers where the caliper is fitted on. :P Quote Link to comment Share on other sites More sharing options...
ScotchDave Posted June 6, 2005 Report Share Posted June 6, 2005 It is not unknown for the disc to rub on the top of the calliper if it's very ovalised, or if your fork mounts are messed up. :P Quote Link to comment Share on other sites More sharing options...
tom e Posted June 6, 2005 Report Share Posted June 6, 2005 (edited) Adjust the spacers where the caliper is fitted on. (Y) ← Thatll be what is wrong, it is my old mono mini (i think) - rotor is brand new, pads are new, it's been bled and serviced by hope fairly recently.. so there can't be anything wrong with it apart from that..

Luke Drewery Posted June 6, 2005 Report Share Posted June 6, 2005 Hydraulic discs, particularly hope are prone to rubbing on the rotor constantly. My mates have had numerous hope discs from the old m4s to the mono mini (which he runs now) and that rubs slightly. Im not sure that there are any tricks to stop it rubbing apart from those mentioned, but if it is only rubbing slightly then i wouldnt bother with it, its not worth the frustration lol.

ian Posted June 6, 2005 Author Report Share Posted June 6, 2005 yeha i tihnk it is a case of just using the shims to move the caliper around a bit. thanks for your help Quote Link to comment Share on other sites More sharing options...
F-Stop Junkie Posted June 6, 2005 Report Share Posted June 6, 2005 Bottom line is that the mini will probably rub. The old calipers had return springs to pull the pads back, but the newer ones rely simply on the pads being knocked back into place by the disc as it rotates, hence it will rub as it is designed to do so. I know some don't, but they're the lucky ones... Quote Link to comment Share on other sites More sharing options...
Tartridge Posted June 6, 2005 Report Share Posted June 6, 2005 Hmm... theres a helping hand from the return spring in the lever. If you pull the brake on, and off again... the pistons do actually return. A well set-up disc brake does not rub. Fiddle with your shims Ian, as has been said (Y) Quote Link to comment Share on other sites More sharing options...
