It's also not a bad idea to take the caliper off and clean and grease the pins that it slides on-or even replace them if they are real pitted etc,..Also dont forget to clean the little groove thatsplits the braking material in each pad--they get a lot of build up in there.Changing your fluid is a good idea-if it's not clear in color then it's got some moisture in it,as they all do with time/use,.Those type's of things goet overlooked on a lot of bikes and is what usually makes the difference between an old bike still working great-or turning into a wreck,that needs way too much $$ into it to bring it back.
