help with brakes on 1988 toyota pickup 4wd

i have a 1988 toyota pickup EFI 4WD, i have a question on how to properly bleed the brakes. I just replaced the master cylinder with another oem one, I normally know how to do this type of procedure, but this ones got me stumped.....
first of all the rear drum brakes are both bleed but when i go to bleed the front disc breaks no fluid comes out when the pedal is pushed down.

second of all if it does have something related to bleeding the LSPV how do i do that properly?

i anyone can help that'll be great, and if it can be done without a mechanic that would be great also, since im a college student and dont have the funds....

basically you have to bench bleed the master or there will be an air bubble trapped in there that wont be bled out (the stroke is too short or something from the brake pedal) so take off the master- either get little plugs that fit in the brake line holes or better get a little dealio that recycles the brake fluid back into the reservoir as you pump it till no air bubbles come out- then you can bleed it like normal

Make sure your bleed screws are not plugged up, maybe your bleed screws or calipers are just corroded and totally screwed up.
