I'm getting ready to bleed the brakes and the ABS unit and I've been reading some archived posts on the subject and have a few questions.
1. Can the ABS unit be bled without BUDS, and how?
2. What is De-Gassing the new fluid, and how?
3. Is DOT 4 required?
4. I have a power bleeder with a one-way valve (that I haven't used before but I've read the Destructions and it's ready to go) is pumping the pedal necessary to get a firm pedal?

Thanks for your help
