Model MV6835 Vacuum Brake Bleed Kit extends the capabilities of the MV6830 Vacuum Brake Bleeder by including the MVA6832 Clamp-on Auto-refill Kit. While the bleeder can evacuate up to 2 quarts per minute, the refill kit ensures the master cylinder does not run dry of new fluid, making this kit an extremely efficient method of bleeding hydraulic brake and clutch systems.
