I guess this is good if you have other vehicles, but this looks like it would be useless for a Dart, which does not use banjo bolts. My brake lines didn't drip more than a few drops when I removed my rear calipers using the exact method described by @Bullfrog. I used a rigid vacuum extension to press the seat into the brake pedal to keep the brakes applied.Reviving this because there's a product just for this kind of thing. The FLSBAN by S.U.R.&R. AUTO PARTS INC. is a spring-loaded clamp assembly that's meant to plug banjo bolts. It's less than $10 from Grainger and I also saw it listen on Napa's website. I attached a PDF that has a few images of it and its variations in use. I haven't used one myself, but it looks like something I'm going to get soon for how often I work on brakes and how much I hate to work around a caliper being hung up on the suspension.
