    Brakes pressure seems to fade

    So whats up guys, I have a 90 accord lx. Over the course of a few months I've began to notice more and more my brake pedal sinking to the floor while at stop lights. For the 90 seconds I'm at a light the brake pedal slowly sinks about an 1 and half inch or so. Basically like its a loss of pressure. So this leads me to my question. Could this possibly be a brake booster issue? I've looked for leaks and checked my brake fluid level which has remained a constant so its not leaking. The car brakes fine when applying the brakes to slow normally but if im just sitting there applying pressure it drops noticeably and this drop forces me to apply more pressure to keep the brakes holding the car on a hill.

    Any ideas ladies and gentlemen? Thanks in advance for all that take the time to help.

        i'm not sure if the brake booster could be involved or not... you'll have to wait for someone else to chime in on that one

              Your master cylinder is on it's way out. A bad booster would make a hissing sound, like a tire leaking air.

                Would you hear this from inside the car? is it a constant hiss or only when you hit the brakes?

                  OP has a bad master cylinder, a bad booster won't always make noise but will result in the brake pedal being hard as stone.

                    Yeup, sucks when the brake booster goes, but it will most likely be a bad MC. Or it could even be just the seal where it mounts to the brake booster.

                          right underneath the brake fluid reservoir. just a few bolts and lines to undo then you just switch them out.
