Question about 2000 Chevrolet Blazer
When you stand on the brakes does the pedal feel soft or hard? If soft the chances are you still have air in the system. Tighten (not too much just enough to prevent the escape of brake fluid) all the bleed nipples. Now make sure there is fluid to the maximum in the master brake reservoir. Stand on the brakes to extend all the slave pistons as far as they can go with the current situation. Starting with the the right back (as you correctly did originally) put your finger tip over the end of the nipple and undo it with an open ended spanner by only a quarter of a turn. Have a friend step on the brake pedal. When he has got to the bottom of travel push your finger hard on the nipple tip and tighten the nipple gently with e the spanner. Your friend can now release the brake pedal slowly. Again ask your friend to press on the pedal and then you undo the nipple a quarter of a turn to bleed of the fluid (and bubbles). When your friend reports that the pedal is on the floor, again tighten the bled nipple. Again your friend can only now release the brake pedal slowly. There will come a point when your friend will notice some resistance to the pedal before you slacken the bleed nipple to bleed the fluid. Keep bleeding this brake until a quarter of a pint of fluid has been pushed through and now tighten the bleed nipple firmly. Add fresh brake fluid to the brake reservoir under the hood. Now repeat this process with the back left wheel, then front right and then front left. The important thing is 1) ensure that the brake pedal is never lifted until the bleed nipple is tight otherwise air is sucked in through the nipple; having your finger tip on the end can help avoid this and 2) to ensure that the reservoir is always full of brake fluid so that only fluid can enter the system and not air 3) that you bleed plenty of fluid through the system, when you replace brake lines it is surprising just how many little pockets of air can hide in it. Good luck
