Anyone check the temperature of their brakes
Are there any of you that have checked the temperature of your disk brakes after 30 or 45 minutes of heavy use. Are the front and rear disk about the same temperature and what temperature were they?

Measure temperature where? Wheels, hubs, calipers, rotors?
And what should the temperature be? Disk brake rotors can briefly get up to 600 C when the brakes are being used hard (I've seen them at orange-red, about 1000 C, on road racing courses), but rotors cool quickly without transmitting all that heat to the calipers. Pads, of course, have to be selected to not vaporize or glaze at whatever the maximum rotor temperature.
Calipers should not get above the wet boiling point of the brake fluid, typically 140-155 C (280-310 F).
