sup guys, maybe u can help me solve my problem. I have a 92 civic hatch dx and for the past couple days when i step on the brake pedal gradually like when your rolling backwards or frontwards out of a driveway the pedal goes right to the floor. It never happens when i'm driving normally and i try to stop. It's driving me nuts, i replaced the brake master cylinder with a used one from a running car and re-bleeded it along with the brakes and still nothing!..does ANYONE have any input, ideas or suggestions...thank you very much.

you may have air in the system still check for leaky calipers and wheel cylinders.

Yeah... it could also be a vacuum leak at the brake booster, or a bad booster. Sounds to me like a bad booster/leak simply because at normal driving everything seems fine.

there is a leak somewhere in the system.... check the stuff bbarbulo said ... then make sure the master cylinder is topped up and then let the car sit for a day ... most of the air air that are in the lines before the calipers will go to the master cylinder...

then fill the master cylinder again and bleed the brakes both front and back in the correct order....
