I did mine and did not need to use a vacuum tool. Just leave the key off after releasing the park brake and then start with the left front. Put a rubber or clear hose on the bleeder and put it in a clear container with enough brake fluid in it to cover the bottom of the hose. This will keep air out. Open the bleeder and slowly pump the brake pedal until all the dirty fluid comes out (keep filling the reservoir with fresh fluid so it doesn't run dry. Shut the bleeder and repeat at right front then the rear. You can use the vacuum if you want that should work fine as well. I had a vacuum tool but turned out not to need it.
