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.

7.1. Place the hex end of the wrench over the wheel cylinder bleeder valve. 7.2. Immerse the opposite end of the hose into a clear container partially filled with clean brake fluid.
8.1. Place the proper size hex end of the wrench over the caliper bleeder valve. 8.2. Place a clear tube over the caliper bleeder valve. 8.3. Immerse the opposite end of the hose into a clear container partially filled with clean brake fluid.

It's very possible to be the master cylinder, the o-rings on the piston could be worn, letting the fluid seep back through instead of getting full pressure through the lines. Could also be the brake booster.
Try changing the master cylinder first, which is cheaper and easier, and see if there is a difference, you'll need to bleed the brakes again.
To check the booster,
With the engine off, pump the brakes until the pedal is hard, then hold pressure on the brake pedal and listen for air escaping, or the pedal goes slowly to the floor, Do that after the master cylinder has been changed, at least that will be eliminated.
