I dont think this is a brake problem, IMO it's a wheel bearing going bad, especially if you did a brake job 4 months ago.
I wouldn't drive it far, as the bearing could fail and you could possibly lose a wheel while driving.
If it is a brake issue, the excessive heat could damage the rubber seals and dust cover sin the calipers, or could cause the brake linings to separate from the backing plates, either of which is not a good cenario, and could end up with a loss of braking while driving.
IMO, park it until you get time to check it out, brakes or bearings are not something to take a chance on, always use the best rated parts you can.
