Mushy brake pedal after 1000 miles This just started yesterday, seemingly out of nowhere. When I push the brake pedal it's mushier than it used to be. If I push hard, I get more resistance at first but then it slowly sinks toward the floor as a I continue to press. If I push softer then it just sinks toward the floor. I still have plenty of stopping power. If I push the pedal repeatedly then it builds up more resistance ("pump the brakes") but then the resistance calms down and it becomes mushy again.
