Was sick for a few days..
It has warmed up some here and I've noticed over the past few days
that my brakes are working differently. when it is around 65 degrees
or so there is no noticable issues (other than the ABS light coming on
a half mile down the road), but when it gets up into the high 70's
there is noticable spongy-ness in the brakes.
When stopping they will slowly keep going to the floor. Once at
the bottom the car doesn't move, but the hotter the car gets the less
longer it takes to stop, or I have to push the pedal more..

Could this affect my ABS? I know ABS doesn't affect the main
brakes, but could a faulty (perhaps master cylinder?) component in the
main brakes affect the ABS?

Thanks for any suggestions!!
