I'm getting ready for my 12,000 mile service and want to do it myself. I bought a MightyVac and then looked at Fred's video where he recommends doing the brakes without the vac because it is messy. I'm confused why it would work on the clutch but not on the brakes. If I have someone helping , wouldn't it be possible for one person to handle the fluid level while the other person does the vacuum pumping until the brakes have been bled and new fluid starts coming out? Any comments? Thanks in advance for your advice.
