Lots of info on the web if you look.. Here's one.http://www.popularmechanics.com/cars/how-to/a1495/how-to- bleed-brakes/ On larger vehicles I used to just leave the bleeder screw open a tad for a number of hours and come back and close it.

without any rear brakes that thing isn't remotely safe , what don says is gravity bleeding , if you open the bleeder with the cap off the reservoir brake fluid should be coming out slowly , I get a length of hose over the bleeder so that no air can enter the system then with the cap on gently , not more than 1 or 2 inches, push the peddle you should feel it stiffen up , if you're not getting fluid back there .you got problems . I had that situation and what I found was someone disconnected the line at the master cylinder and put a small screw in the fitting to block it off because the rear line was leaking leaving me with only front brakes , sliding to a stop on wet roads .

If you got air into the ABS system you will need a dealer to bleed the air out.
