Not A body put new master and front calipers on motor home,chevy p 30, whats the best way to get fluid to calipers without gettin air in lines? Did bench bleed on master got all the air out of it.
Thanks

I have not done this myself, but I learned that you can gravity bleed discs.

Open valve on caliper and let the fluid flow from master cyl to caliper. Be sure to keep master cyl topped off.

Does not work on drums due to residual pressure valve.

Yep, did it on my tool trucks for 3 decades. The bleeder should be at the top, crack it loose, put a pan below to catch the overflow and let her go. Like Dana said, make sure the reservoir doesn't run out. I always closed the bleeder and pumped the brakes up and bled again. Do the passenger side first.
 
yep .first open master ; fill it ; open right front bleeder screw and let it drip until you see no bubbles ; close that bleeder and open left front bleeder and let it drip ; close it when there are no bubbles ';close master cap ; go into vehicle and lightly apply brake pedal a couple of times until you start feeling resistance . open master cap back up and fill it ; open right front bleeder and re=bleed it until no bubbles ;close it and do the left front again ; once you see no bubbles close the bleeder; you should only have to gravity bleed it three times . If you have an assistant handy you can have them apply the brake pedal and lightly loosen off the master cylinder lines one at a time and you may get a spurt of air out from them as well . after that you should be done ; if the pedal is mushy you may have to check the rear brake shoe adjustment may have to bleed the rears as well because you did put a new master on it and may have gotten air in the rear wheel cylinders as well; actually more than likely did.......
 
Thanks for all the help I'll get on in the mornin too hot right now July in south TX
