Seems that this is accurate for ABS equipped cars. Both the 5-series Bentley service manual and the 7-series shop manual indicate that you should pump the brakes a minimum of 12 pumps each time you open the bleeder valve. This is necessary to expel any air trapped in the hydraulic unit.

So do you still have to do all the pumping as instructed in the factory manual? (They say to use a pressure bleeder AND pump the pedal a lot at various times.)


I bought a pressure brake bleeder for Bavarian Auto Sport and it really works great. Allows one man bleeding in less than a half hour. By the way there was a guy with a web page who published a do it yourself spec for making one of these things out of an Ace Hardware insecticide sprayer, but after pricing the Ace thing at about $17 bucks, plus another $9 bucks worth of fittings and a $5 pressure gauge, its seemed worthwhile to buy the thing all assembled from BAS. But, if you want the website spec, let me know by email and I'll try to find it for you. Bob H
