i just replaced all the pads and rotors in my 93 civic si. i have discs all the way around. after bleeding the rear and the front brakes. when i push the pedal down, it slowly goes to the floor. and if i'm slowing down in traffic, i have to slow down in 3 steps to slow down cus its like it pushes all the fluid out so i let the pedal back up to refill so i can depress it again. what do you think, the master cylinder, brake booster, or there's air in the line? it was doing this same exact thing before i even changed the brakes, just not as often. thanks
