I'm at 31k miles and vehicle in question is only 2.5 years old. I've suddenly noticed the brake pedal is more spongy and braking distance has increased. Is my fluid the culprit? I haven't inspected the pads or rotors just yet, but there is no grinding or any odd vibrations. Just a mushier than before pedal and really having to mash on the pedal for the brakes to bite in emergency situations.
