I took off my front brake lines to replace with stainless one's and had to leave my car overnight. When I checked in the morning the master cylinder was empty.

Do I have to bench bleed it? If so, how do I do it.

Or can I just bleed the brakes really good like normal. I planned on doing a complete flush as well, since I have new calipers on front and rear as well.

Bench bleeding requires taking the MC off the car. I found an easier way. 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. Works like a charm.

Thanks, that sounds pretty darn easy!

thats the same thing that i did when i installed a MC on a 240sx. works great!

benchbleeding is for geeks
