  1. Apply the brakes several times with the ignition OFF in order to relieve the brake vacuum reserve.
  2. Fill the master cylinder reservoirs with DOT 3 motor vehicle brake fluid.
  3. Maintain the fluid level during bleeding.
    1. If the brake pressure modulator valve of the antilock brake system is replaced or if you suspect that air is trapped inside, bleed the brake pressure modulator valve next.
    2. Follow this sequence if it is necessary to bleed all four wheels:
    6.1. Right rear wheel cylinder or caliper. 6.2. Left rear wheel cylinder or caliper. 6.3. Right front wheel caliper. 6.4. Left front wheel caliper.
    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.
    1. Slowly apply the brake pedal one time and hold.
    2. Loosen the bleeder valve in order to purge the air from the wheel cylinder or caliper.
    3. Tighten the bleeder valve and slowly release the brake pedal.
    4. Wait 15 seconds. Notice: Refer to Fastener Notice in Service Precautions.
    5. Repeat this sequence, including the 1 5-second wait, until all air is purged from the wheel cylinder or caliper. Tighten the bleeder valve to 7 Nm (62 inch lbs.).
    6. Repeat steps 7-13 at each wheel until the brake system is bled.
    7. Clean any brake fluid off the vehicle that may have gotten on it during the bleeding procedure.
    8. Inspect the brake pedal for sponginess, and inspect the brake warning lamp for an indication of unbalanced pressure. Repeat the bleeding procedure in order to correct either of these conditions.
    9. Fill the master cylinder reservoir to the proper level.

Start from right rear, then, left rear, right front, left front. Fill master cylinder. Have helper sit in car, have helper hold brake pedal down. open bleed screw. fluid and air comes out. close screw. release brake pedal. Continue until no air comes out. Move to next wheel. Keep an eye on master cylinder fluid level after each wheel.

SOURCE: 1999 Chevy S10 Blazer 4x4. Replacing rear pad's,& Bleeding Breaks

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.

Bled brakes on my 1999 chevy blazer still goes to floor

this is an indication that there is still air in the system and the bleeding process was inefficient. Bleed the lines at the master cylinder first by loosening off the lines and holding the pedal down until the lines are retightened. Then starting at the longest line first bleed the system finishing at the shortest line . Keep the fluid level in the reservoir topped up at all times.

1998 chevy blazer when we replaced brake booster and now it will not shift out of park whenits started

Not sure I am following your question, or maybe questions.
If you can not shift out of park with the key on, the brake switch on the pedal may be faulty or out of adjustment.
If the warning light is on, it could be the fluid level sensor in the master cylinder, or the parking brake switch.
If you have no brakes after you try bleeding the master cylinder, the rod inside the booster may not be connected correctly. If you replaced the master cylinder along with the booster, you would need to bench bleed the master before installing it in the truck.
