4-pot calipers unequal pistons, which way round?

should the larger piston be at the top if leading and bottom if trailing or the other way round?

Thanks, Paul

Fit them with the bleed nipples at the top.

Sound right to me, the smaller bore piston will move further and engage the pad on the leading edge first, preventing pad judder.

DO NOT PUT ON KNOB OR BOLLOCKS!

Small piston leading edge is the correct way.
