I have a 1999 Plymouth breeze and just replaced the rear brake lines and can't get them to bleed
1. Use a turkey baser to remove all the fluid from the reservoir. It's likely empty already if you did rear lines. Also, pack rags under the reservoir to catch spills.
2. Use a brake line wrench to crack the bleeder valve. (not OPEN, just see if it moves) Attach a 2' pc of surgical tubing to the bleeder. Run it into a jar. Pour 1" of fluid into the jar. I like to duct tape the jar to a board to prevent spills. Tape the tubing to the jar too.
3. Have a buddy sit in the driver seat. Have them tap-tap and hold steady pressure on the brake pedal. (you don't have to KILL it) When they say "K!", you open the bleeder. Note the passage of air bubbles and fluid into the tube. After about 4 seconds, close the bleeder and repeat. The first wheel will take a WHILE. Each after will be a bit quicker. Watch the accumulation and quality of fluid in the jar for a clue as to how you are progressing.
4. Top off the reservoir and repeat for the next wheel. Bleed, RR, LR, RF, LF (generally. some cars vary).
The pumper buddy must know NOT to drive the pedal past the normal distance or else he'll damage the master cylinder and it will have to be replaced. Also, he must know NOT to lift his foot before you close the bleeder, else he'll draw air back into the system. Just keep steady pressure. He'll feel the pedal drop as you open the bleeder each time. Takes PATIENCE.
They sell vacuum bleeders, but they suck. They're cheap tho.
They sell pressure bleeders and they are GOOD if you can find one to fit your car. They're expensive tho, like $60. MOTIVE makes one (I have it). These work by pressurizing the reservoir. That way you can bleed without a buddy. There's two methods with these. You can pour the fresh fluid into the pump and do the whole car without stopping. I find it messy. I like to top off the res and pressurize each wheel. MUCH cleaner.
Both systems work fine tho.
