Hey Riley, if you don't have access to a Snap-on " scan " tool like Solus (or whatever Matco's, Mac's, or others equipmemt is called), then you will have to manually bleed from the ABS unit itself. This is a messy and time consuming affair. There's no guarantee that you will completely bleed the ABS unit entirely and so you will have to wait until your brake pedal feels a bit spongy (after/during driving), get a partner, bleed the brakes and repeat as necessary. Some ABS units will have a seperate bleeder screw that you can use (I'm not sure if our C5's do as I've never bleed the ABS unit on mine), however it will end up being the same result. The "scan" tool procedure is about 5 minutes or so. Even if you have to repeat it, it will only take another 5 minutes or so. Hope this helps.
