Bench bleeding requires taking the MC off the car. But there is an easier way to do this. Get yourself 4 short (2 - 3 inch) steel brake lines with one end flared on each one. Attach the flared ends to the MC in place of the normal brake lines. Now attach a clear bleed hose on the other end of each line and route them into the resevoir of the MC. Fill the resevior with brake fluid and start pumping the pedal. This will bleed the MC in a matter of seconds.
