Sam Styles Posted November 9, 2010 Report Share Posted November 9, 2010 sounds like you have lost fluid. try looking for any holes, or cuts in your pipes. or generally look for fluid coming out and re-bleed you brake Quote Link to comment Share on other sites More sharing options...
trials owns Posted November 9, 2010 Report Share Posted November 9, 2010 pads in close to the rim with tpa all the way out? if they are probely a poor bleed or you have a leek. what is it bleed with? if water its more than likely it has frozen if left in a cold place.

Ali C Posted November 9, 2010 Report Share Posted November 9, 2010 your piston is bottoming out in the lever. Unwind the tpa, set the pads up as flat as possible and give the brake a bleed. Quote Link to comment Share on other sites More sharing options...

Ali C Posted November 9, 2010 Report Share Posted November 9, 2010 well for starters you shouldn't rely on using the tpa for making the pads closer to the rim, move the cylinders closer instead. As for leaking, unless you have changed the hose or kicked the crossover, I doubt it. You said you bled it recently, without sounding harsh and if you don't know some of the top tips then you probably bled it incorrecly.

murph82 Posted November 10, 2010 Report Share Posted November 10, 2010 Ali, obvious question,what are the top tips?! Quote Link to comment Share on other sites More sharing options...
Ali C Posted November 10, 2010 Report Share Posted November 10, 2010 when I bleed a brake, I usually put the syringe in the caliper and bleed from the bottom up, the theory is that air likes to ride and bubbles will come out easier if they are going up the system. Once I have done that, I put the syringe in the lever but leave the bleed bolt in the caliper. I then pump the lever while turning the whole lever around the bar to make sure any trapped air gets a chance to come out. The bubbles will come out of the lever into the syringe and be replaced with fluid. Works perfectly every time. Quote Link to comment Share on other sites More sharing options...
Ross McArthur Posted November 10, 2010 Report Share Posted November 10, 2010 I find bleeding my brake under water in a basin helps a lot. It means that while you bleed, air comes out but has no chance of getting in (As long as the syringe has no bubbles in it!) I use a big enough syringe so that one full pump is far more than enough water to fill the whole system. As has been said, make sure that the TPA is wound all the way out before you start. I also leave all the bleed bolts and tools under the water while I work - maybe too anal? Quote Link to comment Share on other sites More sharing options...
JD™ Posted November 10, 2010 Report Share Posted November 10, 2010 Is it 'going hard' because your pads are hitting the rim? When it happens, does your wheel move slower? Quote Link to comment Share on other sites More sharing options...

When it happens, does your wheel move slower? no it not like that it goes halfway then suddenly goes rock hard Quote Link to comment Share on other sites More sharing options...
