Recently I noticed that the brake pedal on my Focus seems to sink to the point of almost contacting the floor mat. It seems to happen once every few months, and only occurs once.
In terms of maintenance, the only thing I've replaced are the front pads and rotors. Everything else is OEM from 2007 (car has 100k miles currently).
Any idea of what could be causing it? I recently checked the drivers side floor mat and didn't notice any leaks (from the master cylinder). I've never encountered this issue on any car I've owned before.
thanks in advance
