Aii_Aitch Posted June 8, 2012 Report Share Posted June 8, 2012 Just bought a new rotor to fit my front mono mini (i've never used it before, but it's second hand). Once I had it bolted onto my front wheel, I tried to put it through the pads on the calliper and it won't fit. I know how to align the brake, etc. but the space between the pads seems to be 2mm too thin for the rotor to slot into it. The lever has no adjustment screws/knobs/whatevers, so I'm stumped as to what to do. Can anybody help? Quote Link to comment Share on other sites More sharing options...
mr_malcolm Posted June 8, 2012 Report Share Posted June 8, 2012 checked to see if the pads are just stuck out a bit? get a small flat head screwdriver and see if you can lever them back at all might well be the levers been pressed in with the rotor/wheel out and they just need pushing back.

N.Wood Posted June 8, 2012 Report Share Posted June 8, 2012 Take pads out, use large flathead screwdriver or something to prise the pistons apart. I've found its beter if you do this when the bike is upright, i guess because the master cylinder is then at the top. Put the pads and everything back in, put wheel in and pull the brake a couple times to reset the pads. Quote Link to comment Share on other sites More sharing options...

I've prised them apart with the pads in because i'm not sure how to take them out Now I can get the rotor in and spin the wheel, but it still rubs and if I try to spin the wheel freely it does 4 or 5 rotations before it stops. any more advice?

N.Wood Posted June 8, 2012 Report Share Posted June 8, 2012 Pull the brake a few times to reset the pads into their desired position. The use washers to space the caliper away / towards the fork leg depending on which side it rubs on. Quote Link to comment Share on other sites More sharing options...

I think I'll need to take out the pads, but I'm not sure how to? Quote Link to comment Share on other sites More sharing options...
JD™ Posted June 8, 2012 Report Share Posted June 8, 2012 Google is your friend for that, I'd provide a link but I'm on my phone. Quote Link to comment Share on other sites More sharing options...
Aii_Aitch Posted June 8, 2012 Author Report Share Posted June 8, 2012 Sorted. For anyone reading this in the future: I took out the pin on the calliper and took out the pads and spring from the opening on the opposite side. Then pushed on both of the pistons with a flat-headed screwdriver. The pads go back in a lot easier than when you're taking them out as there's more room. Disc fit between the pads and i squeezed on the lever 3 or 4 times until they got used to where the disc was. Then just a case of aligning the calliper so the pads don't rub. If you have a new disc that looks like it wobbles, it's probably because it's not tight enough on the hub. Quote Link to comment Share on other sites More sharing options...
