Replacing stock master cylinder with an aftermarket unit. Lever feels a bit spongy even after a quick bleed. Looking for best-practice on piston size, banjo/crush washers, ABS compatibility, and bleed order.

    Best answer by Sudhanshu

    Full bleed order matters on ABS bikes: MC → ABS module → calipers. Vacuum + reverse bleed helps.
