These decals are an easy way to measure and document brake caliper temperatures. Just apply one decal to a clean, dry caliper. Ten individual windows mark temperatures ranging from 250° F to 536° F (121° C to 280° C). Each window changes permanently from tan to black when its temperature is exceeded. Sold in packs of 10 strips.
Temperature windows:
250° F / 121° C
290° F / 143° C
330° F / 166° C
370° F / 188° C
410° F / 210° C
450° F / 232° C
490° F / 254° C

Not just for brakes! Use them on your oil tank, transmission, rear axle, or any other part that you think might be getting hotter than 250° F when you're not looking.
