New Brakes....No Stopping Power....help please

You still have an air bubble in the system somewhere if the pedal is not rock hard with
the booster depleted of vacuum. My preferred bleed sequence is RR. LR, RF, LF, and
I use the 2-man procedure.

What bleeding procedure and equipment did you use?

I'm really hoping that's the case. I bled the right rear then left rear, then right front and left front. I had my wife pump the brake pedal twice and hold it while I opened and closed the bleeders all while topping off the reservoir with new fluid.

Sounds like you got it right - the trick is to get the bleeder closed before wifey releases the pedal each and every time. BTW, the 90 ABS unit has no bleeder screws so if there is a bubble trapped there ??? what to do.

One other trick - I have the wife put her other big toe under the brake pedal so it does not go all the way to the floor. Somehow I feel better about not running the master cylinder plunger all the way to the end of its stroke.

Thanks for the feedback guys. I will try bleeding the brakes again this weekend. Hopefully that'sthe problem....
I went with a Valvoline DOT 3 & 4 Syntetic Brake Fluid. Any reason I should go with another brand?

$6 parts store DOT3 until you get the kinks worked out. A good dot3 flush is cheap-you can bleed in some premium stuff right before you go to the track.
