braking temperature

Does anyone know where I can find specifically how hot the average brakes (not race car brakes) get braking at certain speeds at 25, 35, 45 mph etc. or what the mathematical formula to calculate it is?
(I don't have the time or money to install a brake temperature gauge!)


Thanks, cl8

Thanks for the links, some great info, now I need to find out how much MY brake rotors weigh!

If you don't want to take them off and weigh them, contact an on-line parts supplier.
They have the 'shipping' weight for an Echo rotor (since its required to calculate shipping charges).
Subtract about 1/2 lb from the shipping weight, to account for the weight of the box etc and the mass of metal that has probably come off your existing rotors due to wear and you will get a good approximate figure.

Good idea MR, I did go to a couple sites and put the rotors in the cart, when it calculated shipping, it gave me only shipping cost, not weight. Maybe I missed something there.

try www.autozone.com

i just did and it shows me:

10.9 lbs for duralast brand

10.98 lbs for the beck/ arnley brand

Thanks ricebike, I'll have to remember Autozone!
