JonCongreve Posted March 21, 2006 Report Share Posted March 21, 2006 A fresh new bleed should sort that out. A friend of mine had this problem so he bled the brake and it was all good after that.I hope i've helpedJon Quote Link to comment Share on other sites More sharing options...
Lawnmowerman Posted March 21, 2006 Report Share Posted March 21, 2006 Take the pads out, put your finger over one of the pistons so one pushes out, spray gt85 or wd40 etc on the piston and repeat on the other side. Then pull the brake loads so it lubes it all up Quote Link to comment Share on other sites More sharing options...
JT! Posted March 21, 2006 Report Share Posted March 21, 2006 Your pads will not come all the way back if you have any ajstment on your TPA. Which you probably will, so that's nothing to worry about. Quote Link to comment Share on other sites More sharing options...
Martin Grainger Posted March 21, 2006 Author Report Share Posted March 21, 2006 right, ive had a look at all of these things, and ive found out that it is the bit that the tpa pushes to move the pistons (dont know what its called), how can i speed up the master seel/the piston bit in the lever?

Deonn h Posted March 21, 2006 Report Share Posted March 21, 2006 (edited) Drain the oil out pull the piston out and clean it then put some grease or summert on it and put it back in.If it still returns slow take it back out and stretch the spring slightly then put it all back together and rebleed it. .Try bleeding it with water aswell with antifreeze mixed together.

Mooore! Posted March 21, 2006 Report Share Posted March 21, 2006 take the pads out & use a tiny amount of copper slip to free up the slave cylinders, this'll give the lever less work to do when it's pulling the pads back and it lasts longer than wd40.But yea, i'd also recommend a fresh bleed Quote Link to comment Share on other sites More sharing options...
DAB Posted March 22, 2006 Report Share Posted March 22, 2006 If the lever is still slow after all the lubeing, test one thing... empty the master cylinder and remover the hose, dial back the tba to the start, then pull the lever and release, if it's still slow (ie: if the blade comes back and piston stays in cylinder) then more than likely you have ovaled the boar in cylinder and there's nothing you can do.. sorry i've seen this a few times and done it my self. It's from if you have fallen off and hit the lever body.. Quote Link to comment Share on other sites More sharing options...
