Default spongy brakes, where to start?

I drove my kids 95 EX the other day and I found her brake pedal very spongy. It still has decent braking power but the travel is a lot compared to what I remember.

I find no leaks in the brake hydraulics, the pads all have plenty of meat, fluid level is same as always, nothing has been touched since I replaced the pads in the spring.

What should I check first??

If you have rear drum brakes adjusting them would be a good place to start, after that bleeding the system.

disc all around. How would air get into lines if there are no leaks to be seen? I will try bleeding tomorrow anyway.

Air could come from a failing master cylinder, a leak, or the system was opened for a repair and not bled correctly. I see bleeding as a diagnostic tool and you will have to address where the air came from.

Brake fluid absorbs moisture over time. When there is moisture in the brake fluid, it lowers the boiling point. When water heats up, then evaporates and creates air, and there you have it. Honda recommends flushing the brake fluid every three years. Has the fluid ever been flushed? If you have old brake fluid, and an old master cylinder, I would suggest vacuum bleeding.
