Alex Dark Posted April 11, 2008 Report Share Posted April 11, 2008 How about either getting a pre-stretched cable or stretching yours...ill bet that'll account for a lot of the flex Quote Link to comment Share on other sites More sharing options...
basher Posted April 11, 2008 Report Share Posted April 11, 2008 Decent lever and decent cable, Quote Link to comment Share on other sites More sharing options...

steve@banbury-trials Posted April 11, 2008 Report Share Posted April 11, 2008 my caliper flexes a fair bit when under heavy braking ,and i havent heard of any remedies though.this doesnt bother me as i still have the great power and i dont like rock solid levers so its cool.steve Quote Link to comment Share on other sites More sharing options...
tris Posted April 11, 2008 Report Share Posted April 11, 2008 get some loctite on all of the bolts!!!! my bb7 kept coming loose and that was the problem. same with my front wheel bolts, i was doing some fancy tricks the other day and my wheel just fell off!! so yeah get some loctite and dont overtightn the bolts.

Alex@Flawless Bikes Posted April 11, 2008 Report Share Posted April 11, 2008 Get a speed dial 7 lever, one with a tpa and twist it all the way in and that can help abit! Quote Link to comment Share on other sites More sharing options...
froob Posted April 11, 2008 Report Share Posted April 11, 2008 Get a speed dial 7 lever, one with a tpa and twist it all the way in and that can help abit!Twisting it all the way in makes it spongier.Need to have it twisted all the way out The best way to make your brake feel stiffer would be a decent lever and decent cable (such as odysey linear slik cable).Have you set it up correctly? So that the stationary pad is rubbing the disc slightly and the moving pad is a few mm away?Because if the stationary pad is away from the disc, the moving pad has to push the rotor over for the brake to lock properly.Also are the pads hitting straight? If they're not then you need to undo the two bolts holding the caliper onto the adapter, then tighten in the red nob on the outside of the caliper (one furthest from the wheel) till both pads are against the disc. Then tighten up the two bolts and undo the red knob a few turns. I haven't really explained very well but you should get the idea? Quote Link to comment Share on other sites More sharing options...
esfrost Posted April 12, 2008 Report Share Posted April 12, 2008 (edited) Twist it all the way out, i should make the lever and the brake feel stiffer, but less power and vica versa... Edited April 12, 2008 by esfrost Quote Link to comment Share on other sites More sharing options...
eskimo Posted April 12, 2008 Report Share Posted April 12, 2008 One final point not mentioned:a shorter cable will help ever oh slightly. But that's a final tweak. Quote Link to comment Share on other sites More sharing options...
Rant1rave Posted April 13, 2008 Report Share Posted April 13, 2008 If you pull the lever really tight and lock the brake as much as you can then zip tie the lever to the bars in that position and leave it for an hour or so that streches the cable and stops the lever feeling spongy. Hope that helped some Quote Link to comment Share on other sites More sharing options...

Hope that helped someI doubt it would make a remarkable difference to be honest.I've used cable thats 6 months old and my brake still felt as spongy when I put new inner cable on.
