tdubz Posted April 9, 2011 Report Share Posted April 9, 2011 (edited) out riding today and wanted to make a slight adjustment to my lever pull on my rear brake usually quarter turn on it and i get some kind of difference turned it today and nothing happened im going to take a picture of the lever maybe tomorrow because i think one part of the blad and ?piston? have become misaligned causing the tpa pin not to push properly when turned but before i go taking my lever apart i wanted to ask what could be wrong because as it stands the brake works but not as well as it did, the brake is rideable so with the weather we are having dont wanna take the bike off the road so to speak unless its a quick easy fix picture added to help diagnose the problem maybe..... thanks Edited April 10, 2011 by tdubz Quote Link to comment Share on other sites More sharing options...

Mark W Posted April 10, 2011 Report Share Posted April 10, 2011 Sounds like you've sheared the threaded section of the TPA - it's no big deal, you just need an M5 bolt to put in there instead. If you take the lever blade off (easy to do) you can push the TPA assembly out and it'll all become clear. There's a thread about it somewhere on here too...

Martin Reynolds Posted April 10, 2011 Report Share Posted April 10, 2011 Or could your tpa be max'd out? it looks pretty far out Quote Link to comment Share on other sites More sharing options...
tdubz Posted April 10, 2011 Author Report Share Posted April 10, 2011 if the tpa has been maxed out would it just be a case of taking the lever blad off and winding it back in building it back together? removing the lever blade will that effect all the "balance of fluid within the system" resulting in me having to rebleed? thanks Quote Link to comment Share on other sites More sharing options...

You shouldn't have to bleed the brake but you will have to set it up properly at the wheel. That's assuming it is maxed out of course.

Mark W Posted April 10, 2011 Report Share Posted April 10, 2011 Taking the blade off won't do anything to the brake itself at all. Quote Link to comment Share on other sites More sharing options...
