Excessive brake pedal travel

Pads, Rotors & Master Cylinder replaced by my local mechanic but excessive brake pedal travel remains a problem. I brought it to the Honda dealer and they flushed the brake fluid system and bled the lines but that did not resolve the issue, Is there anything else that can be causing such a long brake?
The car is 2002 Accord Coupe EX-V6

Were the calipers checked for binding? Seized caliper slider bolts would often result in low brake pedal and so would a failing master cylinder.
Is the ABS system working correctly?

I have seen bad brake booster check valves cause low brake pedals.

Its going back to the dealer tomorrow morning. The Master Cylinder is new but I don't believe the calipers were checked nor was the ABS system. I had to brake hard today for a deer crossing in front of me and it felt like the ABS never kicked in as my foot practically went to the floor.

Then the abs should be working if the light is out and you have abs on your car.

It has the ABS system. Was reading elsewhere that it may be caused by a leaking wheel bearing also but I have no signs of any leaks and the Master Cyl is full.

Thanks for all your help. Will post the results if the dealer can locate the problem. It just seemed odd to me that after changing rotors and pads all around that the car would develop a stopping problem. This was just preventive maintenance and the car didn't actually need pads or rotors at this time. The car actually stopped better before.

I have seen some of the aftermarket brake pads cause extra brake pedal travel. Do you have the old brake pads?

No, I had no reason to keep the old pads and I assume my tech threw them out by now. That's an odd one but I did have Raybestos on the front, replaced at about 70,000 miles without a problem and the rear's were a no name brand thrown on by a shop I really didn't care for.

Were the old pads worn evenly or sloped?

I think evenly but the front rotors were definitely warped.

What you need to do now is to check if the slider bolts are seized. Quite often when there are insufficient lubricants on them, they tend to stck when new pads are installed. One more thing to check would be the handbrake cables.

I have seen many cases of wrong adjustment whereby the rear brakes would not self adjust and this would also result in low brake pedal.

If they live where they salt the roads then the ebrake cables seize caliper pins etc.

OK. Thanks for all the replies guys! I just returned from my local Honda dealer. Their recommendation afer bleeding the brake lines was for me to go back to my local mechanic that installed a new Master Cyl or let them, the dealer, install a "Honda" Master Cylinder. My local mechanis installed a brand new "Wagner" Master Cylinder last week after receiving a bad one from the warehouse initially.
At this point, I think I need a local pro to REALLY check things out!

New parts failing are not news and that is a logical explanation and since they have inspected the problem, we believe the diagnosis should be correct.
