Adjust your rear brake shoes. Then rebleed the system. Start at the master cylinder Bleed master first then the wheel furthest away from the master (right rear then left rear then right front then left front. Do that and your pedal should be good.

have one person in the blazer pumping the brake pedal and then hold to the floor, crack the bleeder then tighten, release pedal, repeat till all air is out one side at a time, if this does not work then your ABS unit is bad witch if u follow your lines from your master cylinder u will find a black box with a motor on it, or the master cylinder itself is bad, it also can cause u to have no pedal, replace the master cylinder first, most likely cheaper.

SOURCE: spongy brakes after bleeding
If the brakes are spongy, THERE IS STILL AIR IN THE SYSTEM. Bleed brakes again, and a 3rd time if necessary. If you are MANUALLY bleeding, by having a helper pump up the brakes, make sure they hod the PEDAL DOWN till you close the bleeder valve, or you will **** back in more air. Start bleeding the brakes from FURTHEST WHEEL, which is usually R/R. Hope this helps

Honestly your guess is as good as mine. But I don't think the master cylinder is NOT bad you still have air in the system. Get a big bottle of brake fluid bleed all four sides until you run out of fluid or your brakes work properly. You should divide the bottle's content in four, then use each quantity in each side. You'll be removing air and contaminated fluid from the system. Get a small hose that fits on the bleeders and an appropriate container. I have a good feeling if you do this your brakes will work just fine. I don't know how you are bleeding the brakes. I'll let you know the proper way just in case. This is a two man job, with the wheel off, have someone start the car. Have them pump the brakes a few times to get pressure. 1With the brake pedal UP open the bleeder, 2then have your assistant press the brake pedal all the way down and leave it completely pressed down. 3Close the bleeder valve, once close and only with the valve closed have'm release the brake. Repeat as necessary, bake depressed, open valve first then press brake. DO NOT depress until valve completly closed. Close valve THEN depress. Good Luck!

Did you adjust the rear shoes out? If the rear drum brakes are out of adjustment they will give you a lot of pedal travel. If the pads are worn have no fear of that U-CLIP brake spring, just change one shoe at a time. Take the spring off one side, change the shoe, put the spring back on the post and do the same to the other shoe, no problem.
