EMPI 20.6mm Dual-Circuit Master Cylinder — Four-Wheel Disc Conversion (16-9554-0)

EMPI's 20.6mm dual-circuit master cylinder is the standard fit for four-wheel disc conversions on '67–77 Beetles. The larger bore moves more fluid per stroke, which firms up pedal feel once you've added calipers at all four corners.
