Yes, and let me reiterate, DO NOT COME TO A COMPLETE STOP. Find a place where you can either let the car coast awhile for them to cool before stopping, or else a place where you can get home without any stoplights.
On my 85 I even used the parking brake to drive home to avoid using the front brakes.
If you come to a complete stop on hot brakes you can heat check the rotor. If it doesn't damage them it will at least make them look terrible. Heat checking on my wilwoods left pad marks for a long time before they finally wore past.
Heat checking the rotor will cause a hard spot, then as the rotor wears a little the hard spot will wear less than the rest of the rotor, causing a vibration when on the brakes. Alot of people mistake this for a warped rotor, when in fact it is just the hard spot not wearing as fast as the rest of the rotor. If the heat check spot is bad and deep enough turning the rotor is worthless, you will need to replace the rotor. I have done this twice myself, till I found the proper way of bedding rotors and brakes. All companies should put these instructions in with new pads. I had no idea I was screwing up till several years back when I discovered the method of bedding brakes.
