Dwarf Shortage Posted August 8, 2010 Report Share Posted August 8, 2010 Does it look like this? http://www.trials-forum.co.uk/index.php?showtopic=153946&st=0&p=2158014&fromsearch=1&#entry2158014 Quote Link to comment Share on other sites More sharing options...
josh barker Posted August 8, 2010 Report Share Posted August 8, 2010 buy a new TPA, once they jam up like yours it will happen again, probably about 5 minute after you fixed it. buy a new tpa and a cnc'd tpa adjuster for the strength too.

Dwarf Shortage Posted August 8, 2010 Report Share Posted August 8, 2010 I just knocked mine back in with a hammer, and it's been fully functioning and going strong ever since. Quote Link to comment Share on other sites More sharing options...

Sam Styles Posted August 9, 2010 Report Share Posted August 9, 2010 so how do i fix it then? its the red bit to adjust it that is stuck and i cant turn it when this happened to me... i got a adjustable spanner onto the flat part of the pin... and got a pair of grips on the tpa wheel, and just kept forcing it to turn. you could also use thin nose pliers maybe?

Dwarf Shortage Posted August 9, 2010 Report Share Posted August 9, 2010 Just whack it in, I got some pliers, just gripped it and squeezed it back in. Quote Link to comment Share on other sites More sharing options...
Sam Styles Posted August 9, 2010 Report Share Posted August 9, 2010 Just whack it in, I got some pliers, just gripped it and squeezed it back in. his is not like yours.... the tpa wheel has got stuck on the pin. not the whole tpa coming out the lever. the tpa or the pin threads are damaged in some way, which has caused it to get stuck Quote Link to comment Share on other sites More sharing options...
madmanic Posted August 9, 2010 Author Report Share Posted August 9, 2010 thanks guys but managed to fix it befor reading. basically there was just loads of crap clogging the threads up so i did what you said. gripped the pin and forced the red bit round by putting a screw driving against the little square and pushing. couple of the threads on one of the adjusters got damaged but its ok. cleaned them out and greased them back up and fitted. they are not perfect as they both need new adjusters but at least they are working. just waiting for my syringe from tarty and my brakes will be as good as new thanks again for the help Quote Link to comment Share on other sites More sharing options...
