Will Arnold Posted August 8, 2005 Report Share Posted August 8, 2005 i have just cut, filed, angle grinded, the caliper of a formula before and a hope pro lever, and wacked it all together, bled it and its absolutely crap because of the stoopid cylinder size ratio, i cant wait to put the formula lever with the enduro 4 caliper with 205mm rotor, its gunna be the mutts yaw! im not even sure why im posting, maybe someones interested in this kinda thing? ta Will Quote Link to comment Share on other sites More sharing options...

biketrialler Posted August 8, 2005 Report Share Posted August 8, 2005 So what youre saying is you have meshed 2 parts together that arent meant to work together, its crap, and you cant wait for the proper parts? How exciting, wheres the bodge master part of it though? Quote Link to comment Share on other sites More sharing options...
Will Arnold Posted August 8, 2005 Author Report Share Posted August 8, 2005 no no no, thats not whats exciting, when i put the formula lever on the enduro caliper its gunna shit all over everything :huh: i will post pics soooon Quote Link to comment Share on other sites More sharing options...
sfboy Posted August 8, 2005 Report Share Posted August 8, 2005 Because of the ratios, I get you Quote Link to comment Share on other sites More sharing options...

george_bush Posted August 8, 2005 Report Share Posted August 8, 2005 Good luck and if it works you will have a amassing brake and also be the bodge master. Quote Link to comment Share on other sites More sharing options...
Will Arnold Posted August 8, 2005 Author Report Share Posted August 8, 2005 it all works, its a bit spongey because the piston ratio is so silly :D its sooo powerfull (Y) its untrue! now to test it fully........... Quote Link to comment Share on other sites More sharing options...

Will Arnold Posted August 8, 2005 Author Report Share Posted August 8, 2005 its a beast! much better than my avid imo... the lever reach is a bit much thou (Y) nearly at the bar.... i dont really know how to rectify this..... any ideas? thanks Quote Link to comment Share on other sites More sharing options...

RobinJI Posted August 8, 2005 Report Share Posted August 8, 2005 I actually made a calculator for disc breaks using MS Excel. You just put in the piston diameters and lever length and stuff and it would tell you how far the lever would have to be pulled before it contacted and the leverage ratio, but its at my dads house not here (Y) . As for the hope-magura, I really hope you mean a magura disc, because theres no way that an HS33 caliper will work on a hope mini lever, maybe an old closed pro lever but not a mini. really closed systems are the best to bodge because everything is adjustable, Id love to see an old closed pro lever with a magura HS33 rigged up to it, in theory it would be amazing but your wheel would have to be trued with a fuggin micrometer. What you need to do to bodge a good break it find a break that uses large cylinders all round and put the lever off a break that uses small ones on it e.g. Hope XC4 or C2 caliper with a small diameter lever, but I cant think of any closed system ones right now. :D . In fact those and the Giant MPH are the only closed breaks I can think of at all and the MPH is practically a C2. Quote Link to comment Share on other sites More sharing options...

RobinJI Posted August 8, 2005 Report Share Posted August 8, 2005 (edited) As far as lever adjustment goes theres nothing you can realy do about it, its the problem with open system breaks, they always reset to a set position no matter what, which is great with heat build up and padwere but not when you want to adjust the bloody things! All you could do is to put on an Avid Jucy 7 or Hayes el-camino lever instead of the formular. If youre feeling cheep you could just adjust the reach right out and then put a zip tie around to stop the lever going out all the way, but even then i think the open system would adjust to youre bodge and skrew it up again. Worth a try though. Edited August 8, 2005 by Dont you Just Hate it When... Quote Link to comment Share on other sites More sharing options...
RyanRs Posted August 8, 2005 Report Share Posted August 8, 2005 Yea, soz i was on about the old pro lever .. closed system. so used to sayin 'mini' lever now, i didnt realise i typed it ! lol so basically , a closed Pro lever + HS33 pods... and water bleed.

tank_rider Posted August 9, 2005 Report Share Posted August 9, 2005 am i the only person who thinks that any disc with a 205 rotor on a mod is going to be amazing. I have a 160 avid on my stock which is more than enough for me (and my forks!!!). Quote Link to comment Share on other sites More sharing options...
RobinJI Posted August 9, 2005 Report Share Posted August 9, 2005 Im now very tempted to try the same thing with the E4 I have lying around at home, because then I could use the lever (with some closed sytem internals) with my rear maggie and have amazing breaks (Y) , but I'd rather get a No'5 caliper half to reduce my rotor to 165mm.
