Got all 3.
Understand that the 250 is a single side duel pot.
the CBR600F3 are dual side dual pot.
and the TLR is a dual side 310mm rotor, 6 pot calipers. The 600 and the 1000 will lift the rear with two fingers on the lever.
here is a little trick that may help.
the night before you are going to bleed/replace your brakes...
Tie a bandanna or zip tie around your lever, or put something heavy on the peddle.
the idea here is to place the system under pressure for an extended period of time (over night)
what this does is force any moisture, or small air pockets into the brake fluid...
the next day, when you do the bleed/change... all the "badness" goes out with the used fluid and the system is as clean and moisture free as it can be.
this also works on "soft" brakes even with out a replacement, tie it up, should be good and grabby in the morning.
