Has anyone ever heard of gravity bleeding? You're supposed to open all four bleeding nipples on the calipers and let it sit over night with some kind of buckets under the brakes. My friend told me thats the way they bleed the brakes of UPS trucks. His brother-in-law is a chief mecanic there. He tried it on his car and it worked...

Has anyone ever heard of this?

the air in the system is supposed to come out of the system.

Ready, set, open and bleed. That is the way some Honda techs actually do the flush and bleed-gravity is good for that if the system has not been tampered with. At least that is what i was told.

it works... just takes an infernally long time to do it. probably wouldn't take all night, and you'd run the risk of having it run the M/C dry, undoing all your hard work, or lack thereof.

Vince, I have heard not to open more than one bleeder at a time, because otherwise air can track back into the system. It DOES work though, if you have the time, 5-10 min per corner. just keep your eye on the resevoir, so as not to run it dry.

Ill try it out this week a bleeder at a time, 10 min. Ill keep you posted.

I've heard from race mechanics that this way is a great way to bleed.

i think its an ok way to flush the brake lines, but not so good if you have air in it since the air will travel upwards and gravity
wont suck the fluid fast enough to expel the air trapped inside.
