Stu Ritter's new book describes pressure bleeding processes for both ABS-equipped and non-ABS-equipped cars.

ABS cars supposedly need 30 lbs. of pressure to bleed properly. These $100 diyer pressure bleeders for the most part cannot exceed 15 lbs.

I remember a reply Stu made some time back about the speedi-bleeder type units being undersized for ABS cars.

I have ABS and a speedi-bleeder(derives pressure from spare tire) and have bleed the system to my satisfication - no spongy pedal.

My 2 cents.
