Go down to napa and get some speedi bleeders that go on the calipers, they are one way bleeders, they are probably around $30 aset that means total for front and rear. This way next time you have to change fluid it will be much simplier and c heaper than having someone do it. rx7doctor

Just did mine this weekend. I also have rear discs. Had the same prolem. I learned that the stupid "one man" bleeder kit was the problem. When I had it hooked up to the driver's front disc, I could see the fluid (along w/bubbles) going back into the line after letting up off the pedal. Therefore, I knew I was getting no where.
Problem was solved my getting my wife to help by pushing the pedal down. Had her first, push the pedal down and hold it there, then I would crack the line. Kept doing that till I got a good 12"+ long squirt out of all 4 lines. Brakes on a dime now!

Oh yeah, and when installing new m/s you have to reverse the "normal" order of bleeding. You start with the closest wheel to the m/s and work away from it. Otherwise, you'll never get all the air out. This order should be: LF, RF, LR, RR.
You method of bleeding is correct any other time. It's just in this case you are starting with air at the very beginning of the system rather than at the end....

When I changed master cylinder, I noticed it wouldn't work unless the car was beld in sequence. Rears, then front right, then left front (I think it was). The rears not so important, either side first is fine.
The front is the important one. It actually states it in the Haynes manual.
