Not sure if I am the only one with this problem or if this is old news. However over recent weeks my front brake has been a bit "notchy" felt like I had major caliper/master cylinder problems.
In a bit of a last ditch effort to fix the easy stuff I took the pivot out of the front brake lever and found it to be gunged up beyond belief. Some sort of black tar on the pivot surfaces and also on the bearing surface of the master cylinder. Being a naked bike could just be an accumulation of dead bugs and road detritus. Quick wipe with a WD40 coated rag and all the gunge came off. Then re-lubricated the pivot with some new oil (chainsaw oil). Stuck it all back together and it's as smooth as you like now. Not suggesting this replaces the need for periodic caliper servicing etc, but if you suddenly get an urgent dose of the notchies, may be worth a look. To get the pivot out, first undo the nut on the bottom of the brake lever then unscrew the pivot from the top. It is not a simple nut and bolt configuration. And as a bit of a disclaimer, brakes are kinda important so don't mess unless you know when to give up and call in the professionals. Oh and as for chainsaw oil I find it great for any job where you do not want thin oil running away (vertical stuff chains etc) Costs next to nothing and has always done a good job for me. cheers, Mark

Yup had the same problem, after replacing the calipers(needed doing) I just used some std grease. Good init

Glad it wasn't just me then. But extra glad I did it before I parted with many beer tokens at local dealer.
Now all I need is the thread that tells you how to brew super-unleaded and carve new tread pattern into bald tyres then I can enter the world of free biking.

It's not unusual to find the brake lever has a bit of a flat worn on it where it contacts the M/cyl piston, if it's slight then a quick adjustment with a file makes a useful difference to the action of the brake, also have a look at the end of the piston, if worn, (not usual but I've seen it a few times), then the same problem can be caused.

You would be surprised how many people have rebuilt their brakes when the problem was in the pivot, Good on you for figuring it out.
