No. You have to bleed from the slave cylinders at each wheel. You start with the bleed valve farthest away from the master cylinder. A 'one man' bleeding kit makes it much easier and is more effective.

Each wheel needs to be bleed in the sequence specified by the maker . . . . . some master cylinders also need to be bled and have bleeder valves for that purpose.

No. You can use a vacuum system to suck the fluid out at each wheel or a system that pressurises the master cylinder to force fluid out of each wheel.

can do ,but its better to bleed the brakes from the calipers. due to gravity.
