The Foamoi Refresher Posted February 3, 2005 Report Share Posted February 3, 2005 i have just read on the for sale page that the ashton forks disk mount is a couple of mm out is this true? if so is this why i am having trouble with my disk brake? solution to the problem? thanks in advance to any information you can give me cheers, luisio Quote Link to comment Share on other sites More sharing options...
the666ers Posted February 3, 2005 Report Share Posted February 3, 2005 On the older models, the disc mount is indeed very slightly out. Solution: Look at your rotor and see where it is inside the caliper, if it's too high up (e'g catching on the caliper) you need a smaller rotor, if it's too low (eg pads falling off the top of the rotor) you need a bigger one. That was pretty useless, however I remember people saying it's mounted too far down so you need a rotor that's smaller by 3mm, so if you have a 180, you need to get a 177 and so on... Call up hope and ask them to make you one, they will do ANY size you want. My friend had a problem with discs in horizontal dropouts, so got one that was 178mm. It was £25 I think and looks like a standard C2 rotor. The turnaround was about 5 days as they had to machine the rotor, but they may well have one in the size you need so call them (Y) Hope you manage to sort it out.

colly Posted February 3, 2005 Report Share Posted February 3, 2005 the disc mount is 2mm to low, so if it is a 185mm rotor you need a 183mm, this happend to me, sollution take angle grinder to top of rotor and grind it down till it works, and spins freely. did it to mine, not one problem what so ever (Y) Quote Link to comment Share on other sites More sharing options...

the666ers Posted February 4, 2005 Report Share Posted February 4, 2005 To be fair, I can see how he got confused. I mean how can you say there are "sides" to a circle... James Quote Link to comment Share on other sites More sharing options...

Mr Motivator Posted February 4, 2005 Report Share Posted February 4, 2005 my ashtons are fineo with a disk. I have a 180 rotor in a 185 calliper though, but I took out the washers and put them behind the bolt on the disk mount.. that made no sense :blink: Quote Link to comment Share on other sites More sharing options...

Will Arnold Posted February 5, 2005 Report Share Posted February 5, 2005 i only took 2 mm off in total, my rotor size = 183 mm ← different disk systems have different cleareneces though, maybe you were lucky? if the ashton mounts are 2mm too low then you will need to have a 4mm smaller rotor, with the exception of collys setup (Y) Will Quote Link to comment Share on other sites More sharing options...
