Ross McArthur Posted July 2, 2006 Report Share Posted July 2, 2006 (edited) hi, iv always wondered if having a bigger rottor will acctually make a disc brake stronger?? i know that it helps cool it down quicker because there is more room for the heat to dissapait (if thats how its spelled) dooes anyone know exactly why people say that biigger is better??no smarmy comments now! tawhat i mean by stronger is more powerfull!would it make the hope trial more bitey etc...

adamtrials Posted July 2, 2006 Report Share Posted July 2, 2006 (edited) It will be more powerful as you have more leverage on the wheel as it is a larger "lever" in effect which can apply more stopping force to the wheel. Surely you know basic physics? Edited July 2, 2006 by adamtrials Quote Link to comment Share on other sites More sharing options...
Ross McArthur Posted July 2, 2006 Author Report Share Posted July 2, 2006 so what ur sayin is havin a maggie or v brake should be more powerfull because the are bigger levers in theory?? Quote Link to comment Share on other sites More sharing options...
adamtrials Posted July 2, 2006 Report Share Posted July 2, 2006 Yes, however disk brakes stop on a different scientific prinicipal to rim brakes meaning they are ace And disks work better in the wet. Quote Link to comment Share on other sites More sharing options...

Ross McArthur Posted July 2, 2006 Author Report Share Posted July 2, 2006 not really noticing any difference in my rear maggie in the wet from my front hope trial because the rims ground so if the right precausions are taken to ride in the wet with rim brakes they can be just as good if not better! cheers ned1 thats cool id like to see the bike with the rotor the size as the wheel Quote Link to comment Share on other sites More sharing options...
the judge Posted July 3, 2006 Report Share Posted July 3, 2006 (edited) id like to see the bike with the rotor the size as the wheel It's kinda been thought of with the Ruthless trials bike, have a look at the rear brake: Edited July 3, 2006 by the judge Quote Link to comment Share on other sites More sharing options...
ben Posted July 6, 2006 Report Share Posted July 6, 2006 discs are more powerful even though they have less leverage on the wheel than maguras for a few reasons they have a solid caliper that hadly flexes so you dont lose any power through that also the pistol ratio is 'better' meaning the slaves movr less but do it with more force then maguras dont use this ratio as the pads would move to little and the break would be impossible to set up expecialy with buckles etc. this is also why the RB F1 ergo lever is more powerfull not only does it have a longer lever blade bit it also has a smaller master pistonhope that was helpful ben Quote Link to comment Share on other sites More sharing options...
