Hot water will react chemically with any salt left on the bike, but cold water that hits hot bike parts will just boil away into steam and not leave as much damage, (but remember to up the cleaning schedule!)
If your brakes seized slightly after a few days, then maybe your seals are starting to perish. I had a full brake service done in summer after a couple of dust seals had given up the ghost and mine have shown no bother since then, regardless of weather(I also ride everyday to work.) Worth considering maybe?
