long story short, i put on some cycra pro bends and the way the front brake line came out of the master cyliner, it would run right through the aluminum cycra guard.
there are two finger-like projections on the master cylinder the brake line bolts between. i had to take the line loose and run it below the bottom finger to make it work. i hope this wont hurt anything.
anyway, took the master cylinder cap off to add fluid and bleed the front brake.
there was the cap, then a black rubber piece under than, and then floating in the master cylinder brake fluid was a flat piece of foam just floating around in there.
it was about 1/8 inch thick hard foam and was cut to roughly the shape of the inside of the master cylinder.
is that piece supposed to be in there? if so, what is it for? ive done a few brake line replacements on street bikes and have never seen anything like that floating around in the fluid. i just wanted to make sure its supposed to be in there.
