Open bleeder farthest away from MC, let drip until clear fluid comes out. Keep watch on MC so that it deosn't run dry. Close nipple. Go to next closest and so on until you get all of them gravity bled. No danger to ABS systems. Takes about 1 1/2 to 2 hours to do.
Buy the "One Man Brake Bleeder" from Harbor Freight, some other store, or make one (plastic bottle with hose through cap that goes to the bottom). Follow the procedure above. The OMBB prevents sucking any air back into the brake hydraulics and helps prevent making a mess on the driveway or garage floor. Also with the OMBB you can speed up the process by pumping the peddle a few times, just watch the brake fluid and the OMBB every two to three pumps.
I have a reaction (bad rash) to straight DOT 3 but not to DOT 3/4 Synthetic, so I flush out the DOT-3 and dispose of it. I have done this for years and even when I had the shop with no problems. The DOT 3/4 Synthetic seems to last longer and is less harsh on the brake system components.
DOT 5 Synthetic is for antique cars that only get driven up onto and off the trailer to go to shows or in parades. I would never put DOT 5 Synthetic in my Jeep or my Wife's TDI, it does not react to heat very well.
