Heating up is no problem. They run much hotter than any air temp. I have done 9 to 5 driving for 5-7 days in a row through France, Spain and Portugal up and down mountains and the ambient temp has no affect on the brakes. Maintaining heat longer after you park doesn't affect the braking performance. You should allow your brakes to cool down just like you would on a track day. 20 deg C variation in ambient temp is nothing compared to how hot the pads can run.
