I just bought a 88 crx 1.5 fi I have full brake pedal when the car is off but when I turn it on the pedal drops almost to the floor. I replaced wheel cylinders master cylinders brake booster. and made it a little better but not up to par any ideas?

 

I hope you bled the brakes.

 

yes I bleed the brakes I was wondering what else would cause the pedal to drop?
