You need to start at the farthest rear and bleed it make sure someone is pumping and holding brake while doing this .. then move to next farthest .. then pass front and then driver side until the whole system has gotten air out.. keep your brake master cylinder full all the time..

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.

SOURCE: I need to know how to bleed the brakes on a 1999 chevy blazer

  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.

SOURCE: Brake pedal still goes to floor 2000 GMC Jimmy

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.

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.

Cant get breaks on my 2002 blazer ather break lane breaks


After you fix a brake line, you need to bleed the line. There is air in the line that needs to be bleed out of the line. Make sure the vehicle is not running, totally shut off. First - find which tire the brake line goes to that you just fixed. Two - then have someone in the vehicle pumping the brake three times, then on the third time, have them hold the brake to floor. Three - open the bleeder valve on the brake caliper of the tire that the brake line goes to.(Note - You need the tire off the vehicle to do this.) Four - once the the bleeder valve is opened, and all the brake fluid, and air comes out, close the bleeder valve and repeat the whole process several more time. Each time you bleed the brake line you are releasing the air in the line, and creating pressure with just fluid in the line. Usually three to four tries of bleeding the line will solve the air in the brake line problem and your brake pedal will become hard.

You have air in the lines, you need a dealer to bleed this as it has anti lock and that requires a special tool.

Replace brakes. now they go to the floor. bled air


When you fixed the brakes, did you take the lid off the master cylinder. I just wonder if you spilled out your brake fluid. The only reason the pedal should go to the floor is if the brake fluid is gone or the master cylinder is not working. Check the fuse. Check the brake fluid level. The pedal only goes to the floor if there is no back pressure in the lines between the master cylinder the lines to the brake pistion on the calipers. Please give me a good ratin and keep me informed.

Brakes to the floor(almost) 99 blazer


bleed the brake again. if the pedal goes to the floor with little resistance, then the master cylinder is your problem.
the shim is to depress the noise when you applied the brake. you can skip that, if the brake works without it.
