trials owns Posted July 24, 2010 Report Share Posted July 24, 2010 you could try adjusting the tpa on the lever it could be lazy cylinder pistons, see if they are responsive if not take them out and lube them. the bleed may of got some air in causing it to be weak, when bled was the tpa all the way out? check your tubing on the brake and al the seals to make sure no oil is leaking out.

rab shropshire Posted July 24, 2010 Report Share Posted July 24, 2010 could you give us a run down of your setup ie what pads, rim, clamps your running Quote Link to comment Share on other sites More sharing options...
p_ruskin Posted July 24, 2010 Report Share Posted July 24, 2010 Do you have the standard magura pads? Maybe a new set of decent pads would help the bite and power, i recommend any heatsink pads Also bleed your brake with water and it will feel a lot better Quote Link to comment Share on other sites More sharing options...

rab shropshire Posted July 24, 2010 Report Share Posted July 24, 2010 if you pull the piston out and sparay some wd40 round it that should fix it, but a mildly lazy piston wont make it that much less powerfull Quote Link to comment Share on other sites More sharing options...

rab shropshire Posted July 24, 2010 Report Share Posted July 24, 2010 and by not powerfull what do you mean, is it lacking bite/hold or both when your pads hit the rim can you still pull the lever further to your bars? final question are your pads set up perfectly square to your rim Quote Link to comment Share on other sites More sharing options...

trials owns Posted July 24, 2010 Report Share Posted July 24, 2010 your bleed is dodgie then because of air inside. also make sure the pads are close to the rim. Quote Link to comment Share on other sites More sharing options...
rab shropshire Posted July 24, 2010 Report Share Posted July 24, 2010 if you can still pull the lever further to your bars then it is a poor bleed, try giving it another bleed and it should be fine Quote Link to comment Share on other sites More sharing options...
