The ABS modulator (hydraulic unit) can leak air into the brake system and cause a low brake pedal. A new ABS modulator will be needed if it is diagnosed to be the source of the leak.Google+

Brakes failed at stop sign. Fender bender car in front of me.
Ticketed for accident. Next day, dealer found air in ABS Modulator.
Cost of repair: $1,400. Two days to repair due to part having to be
flown in from California. Honda refuses to acknowledge low milage
rule and said warranty expired. Thank you Honda.. :(

Peddle got soft 3 different times. Went almost to floor last time. super dangerous situation. After Honda giving me the run around they finally realized there was a big problem. Air in system. Replaced ABS system and that fixed it.
i had the brakes redone and the brakes feel mushy like they still need to be bled but they dont.

Brake activation occurs when pedal is 1/2 way to the floor. Replaced rear pads and bled fluid at all 4 wheels FL, FR, LR, and then RR. No difference in brake pedal travel. I suspect air in ABS module. 2004 ABS module is non serviceable as far as I can tell.
