    BL-M985 compatible with BR-755

    2011 XTR levers compatible with old XT 4 piston calipers?

    I've read some stuff on this board stating the new brakes aren't compatible with the old stuff.

    Can anyone confirm or deny?

    Thank You

    Since it's unlikely that anybody has tried that combination yet, it's going to come down to the dimensions of the two different master cylinders.

    The issue will be how big the reservoir is in the master cylinder, as the four pot calipers will require more fluid in the system as the pads wear. The XTR lever reservoir is quite small.

    Not the same Q but....

    Do your think I could make the new lever work with the old XTR caliper?
