Compatible with standard 12 oz (340 g) and 32 oz (907 g) brake fluid bottles, this master cylinder refill kit automatically maintains fluid levels during vacuum bleeding to prevent air from entering brake or clutch lines. The kit includes a 12 oz (340 g) bottle adapter, a 32 oz (907 g) bottle adapter, and three master cylinder plates measuring 3" (7.6 cm) in diameter, 6" (15.2 cm) in diameter, and 4" (10.2 cm) x 8" (20.3 cm) for dual chamber reservoirs. By connecting directly to the fluid container, it eliminates the need for manual topping-off and prevents the mess associated with transferring fluid into a reservoir.
