Question about 1999 Chevrolet Blazer
Did you get a steady stream of brake fluid from the bleed valves at all four wheels? I use a rubber line (from a vacuum line hose) on the nipples and stick the end into a transparent jar with some brake fluid in it. Makes it easy to see how the bleeding is going, air bubbles or all fluid, and there's no chance for air to sneak back in as you close off the bleed valve.
What about the master cylinder? If an internal cup or seal has failed, fluid isn't forced down under high pressure through the lines to the wheels. It only leaks back into the other chamber in the master cylinder. But if you keep pumping the brakes, as people have to do with a bad master cylinder, you get a little pressure built, come to a roolling stop...if you're lucky, you can live a long time... if you're lucky. Well, enough safety illustrations, Kevin.
The ABS system is pretty complicated. If you run into problems, take it to a brake shop. Or see if you need a new master cylinder.

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.

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.

Did you put fresh fluid in the master cylinder? I really think you still have air in the lines. To bleed manually, start with the bleeder the greatest distance from the master cylinder, car running, helper pushing down about half way on brake pedal and releasing 3 times, on 3rd time, holding pedal down to half way depressed point while you open the bleeder valve. Repeat until you are sure all air has been flushed out. Check master cyl reservoir level often, because if it gets low and you **** air into the system, you have to start all over again. Go to wheel next greatest distance from master cyl, repeat above, working your way to wheel closest to master cyl last.

You probably have air between the master cylinder and the abs pump. Fill the reservior and have someone pump the brake and bleed the primary lines at the abs pump. Good luck.
