We recently tested our Katana2 Elise with ULTRAdiscs and Hawk HT10 brake pads and ran some new Temperature Indicating Paint. We used 500, 750, 1000, and 1200 degree F paints for our first test. We painted the front and rear rotors.
As you can see in the pictures, we only burned off the 500deg F paint in the rear. This means we are getting our rear brakes hotter than 500deg F but still less than 750deg F. .
We burned the 750deg F paint in the front. This means we burned past 750deg F on the front but not up to 1000deg F.
For our next test we are going to narrow down our paint choices to get a better indication of actual temps we are running. This is a fairly simple and easy non-intrusive way to find out where you are in the heat range of your braking system. It is a smart approach before spending money on a BBK or venting. You might be amazed that the stock sized system with better pads, rotors and fluid might be enough to keep your brake temps in check.
