I performed my 2 year brake fluid exchange several weeks ago. I pressurized the reservoir to 20 psi and bleed the wheel brake calibers starting at the right rear, working from the farthest to the closest to the reservoir. Only problem I had was that I used more fluid than I should have because the color difference between the old and new fluid was not easily discernible. It would be great to know how much fluid should be bleed from each wheel brake caliber if the old fluid is suctioned from the reservoir and replaced with new fluid. I guess it could be approximated if the lengths of the brake lines were known, assuming they all had the same inner diameter. The shop manual has a diagram but I doubt if it is to scale. Does anyone know the actual lengths of the brake lines?
