There wasnt anything wrong with the brakes but when i have changed the brake pads the pedal sinks but it still stops OK. First i thought it was the Master Cylinder so i have went to HONDA and got a new one. As soon as i slap on the MC i bleed all 4 wheels for like 2 hours and used over 2 large bottle of brake fluid and its still goes down. I checked the brake booster and its find. Can anyone help me ??? i didnt change the rotors but can that be a problem ??
