Well as stated earlier I changed the front pads and now I have bled the system and filled it with new fluid, the brakes however still do not give me the stopping power they should. I can definitely stop, but it seems as though after driving it for a while the brake pedal when applied is soft for about 3/4" and then hard to push, but when it is hard to push there is minimal stopping power, I mean it still stops but its like I have manual brakes amd not power assisted braking. There are no vacuum leaks that I can find and this problem has become rather perplexing. Does anyone else have any ideas what may be causing this issue?

The car again is a 1993 100Q CS.

I just did the pedal pump with my wife pushing the pedal and I was cracking and releasing the fluid. I heard from someone somewhere that I could actually just crack all of the bleeders and take the cap off of the brake resevoir and leave it overnight and all of the air would come out overnight.

Anyhow, would you recommend that I get a proper power bleed and refill done?

Than I would bet the farm you have air in the system now. And are going to need to bleed them. That old school way, actually will do more harm than good. You need to take it somewhere, or buy a bleeder kit. A decent kit will run you about $35 and you'll need it to get all the air out. Did you check the spec of your rotors? I personally don't resurface or change my rotors as much as most people, because I don't care if I have stop on a dime breaking or not. (Have never had to stop on one anyway) Plus I don't like really touchy brakes anyhow. But, if that is what you are trying to achieve. You need to take all these factors into consideration. And most people don't know this, but you really don't need to bleed your brakes when you change your pads. The only time you should have to bleed them is when you introduce air into the system. (like when changing a line, caliper, cyl, etc..) when your changing pads, its true your putting pressing the piston in, but your still not introducing air into the system. My advice would be pull the calipers back off, take the rotors to an auto parts store and have them measured (unless you have a guage) Figure out if you're gonna use the same rotors or not and then get it bled. Imho, your main problem is the air you now have in your lines. Even if you have not gotten to the rear yet, it doesn't matter almost all the breaking is done by the front with the rear assisting (obviousy because the pressure is higher there)

I had some softness after a fluid change, so I took the car for a test drive and activated the ABS system (stomp the brakes/emergency stop). Then I bled the system again, finding air bubbles I didn't see before. Now it's firm. I used a pressure bleeder.
