Thanks Billman.
I have a question about step 1 and 2. If we empty the master cylinder thoroughly, wouldn't air get into master cylinder?

I'm looking to change my brake lines to SS. Should I do a flush first and then install my SS lines and add more break fluids? My master cylinder looks pretty nasty. I figure this way would be using more brake fluid, but will keep my lines clean.

It makes sens to me to drain the entire system to remove the brake lines, then once everything is installed, perform the gravity procedure. In this case your waiting for fluid to come out of each caliper, rather then just turning blue from the old to new fluid.

Thanks for the advise. I was thinking I should go that route as I was looking to paint my calipers. I figure I should take all the down time at once.

Not to overshadow the expert here, but add disclaimer to wipe off any brake fluid if it spills on your paint immediately. That stuff will eat away at clearcoat and paint.

I'm under the impression that you should just rinse it off with water. Wiping can smear softened paint.

Yes best thing to do with spilled brake fluid is hit it with lots of low pressure water.

If you follow the steps in order, you will get no air at all in the system.

I just use flexible airline aquarium tubing. You can get 25ft of it for like 3 dollars. I think the size of the tube is 3/16" but don't quote me on that.

The handbrake is cable driven and independent of the hydraulic braking system. (No, it doesn't matter. Either way is fine.)
