k3lv Posted February 29 Author Share Posted February 29 1 hour ago, husoi said: Not the first time the friction bit of the lever gets worn enough to start to give problems. A good inspection of both the lever and the end bit of the MC piston for extra wear should help the investigation. and yes @k3lv can't go wrong with a trip to Scotland Lever end is a little worn ....piston is fine ,I've noticed the adjuster wheel is also a little loose ...so maybe a couple mm here and there is all adding up . I'd love to ride to Scotland...but when it warms up a little 1 Quote Link to comment Share on other sites More sharing options...
Stu Posted February 29 Share Posted February 29 I strongly advise against trying to shim the lever and the piston You could cause the pads to bind which generates heat and locks on the brakes! A member did this a few years ago with a set of aftermarket levers that didn't fit right luckily he had ABS so the bike came to a rather quick stop without issues! He has to walk home and get spanners to release it I can confirm though that you have stock levers I can also tell you that I have had 2 GSXR SRAD's and a TL1000s with the same brake setup and i they was shockingly bad and also extremely hard to bleed all the air out 3 1 Quote Link to comment Share on other sites More sharing options...

RideWithStyles Posted March 1 Share Posted March 1 i mean holy moly how many miles and brake activations must there have been to make a lever (aluminium) and piston (coated steel) wear out enough for the piston to not move a few microns to a 1/85-a1/4 mm??? 1 Quote Link to comment Share on other sites More sharing options...

She is an old girl now ..I don't know if these levers are prone to bending or just snapping , maybe it's a combo of worn parts and a slight bend , I've ordered a used lever and a set of pattern parts so I can compare .

k3lv Posted March 4 Author Share Posted March 4 The new pattern lever came today ....it is a bit better ....takes a lot more force to pull the lever to the bar ,but it can be done Thanks for the help and suggestions folks but I'm gonna just swap the whole front system .

S-Westerly Posted March 4 Share Posted March 4 If you are going to do that try and replace it with Nissin. 1 Quote Link to comment Share on other sites More sharing options...

Yeah that's what I'm hoping to get , shame would have liked to keep it as stock as I can (even though someone's put an awful under tail thing on it .... luckily one that keeps the original rear light) Quote Link to comment Share on other sites More sharing options...

RideWithStyles Posted March 8 Share Posted March 8 Love it MB. looks like its been scratched to death by every owner and mechanic going....nearly every avenue have been check and assured by yourself but doing more to it or finding it that is masking or making the problem? you could Very very gently (and i mean very f ing gently) with very very fine sand paper or file clean it up (smooth it out) and try one last ditched time? failing that then try a different MC. with the way this saga keeps going now were going into the thought of are all the components actually clean with smooth surfaces including for the banjos and crush washers to mate to at the correct torque? is there any tiny cracks or dings anywhere that might suggest high impact or being dropped previously? are these things original to the bike or bodged from a scrapper? correct one time use (ideally) for those copper washer badboi's if your going to ensure it's properly done.

All new steel hoses,washers,and banjo bolts all done up with a torque wrench. Got it all steipped off the bike now as I'm gonna swap the whole system out , so now I can bench test the whole system over and over and just see whats causing the issue 2 Quote Link to comment Share on other sites More sharing options...
