I have a '96 accord and having a brake problem. The brakes stop fine but while sitting at a red light the pedal gradually goes to the floor. I have checked the wheel cylinders and all are ok, the booster was checked and is ok, and I don't seem to be losing any fluid. Does anyone have any idea what the problem might be? Thank you.

 

your brake line might have air in it, ask a mechanic to check.

 

Sorry, I forgot to say the brake lines have already been bled, any other ideas?

 

sounds like your brake master cylinder is faulty get it replaced asap as it will get worse
one sign is if you look under the master cylinder you will see fluid leaking on the booster but not always .

 

That's classic for a bad master cylinder. Usually it leaks back into the reservoir, so you normally won't find any leakage.

 

I have selective reading problems.
