Honda, Civic, 1995, 175,000 miles. It seems like my brakes get a bit " mushy" (they engage closer to the floor of the car) when it's hot outside and I've been driving for awhile. It has to be pretty hot, but living in So. California, that can be frequently. Does this seem possible? What is (likely to be) wrong? I'll definitely take it in, but I'd love to be armed with a little more information when I take it to my mechanic.
