I know this subject has probably been covered a lot, so please forgive and bear with me. I've just changed my front pads and rotors and am ready to bleed/flush the brake system. I understand the pro motive pressure bleeder is the way to go and have read that the vacuum type bleeders are to be avoided,but I just happen to have the Griots vacuum type bleeder. Has anyone had good results with this?
Do these cars have brake pressure compensting valve? I have the car up on jack stands. Will I have to block up the rear wheels to be able to bleed the rear calipers? Thanks for any help on this and thanks for the 993 forum and Rennlist in general

If you get a ggod seal at the nipple a vacuum bleed is ok, the danger is a poor seal and back flow of air in to the system,

Some people can get their hands in to bleed both sides of the caliper from the back w/o pulling a wheel. I can't so always pull all the wheels.

A pressure bleeder is cheap and is the surest way to get it right

don't forget to do the clutch at the same time

yes there is either 1 or 2 p/v's on the rear circuit depending on which option your car has but they do not affect bleeding procedures
