Incorrect my learned friend.Lower said:Hammerite isn't up to withstanding the temperatures the calipers can get up to with hard use. You really want some proper brake caliper paint which the like of Halfords et al sell.
Personally, i'd go for black or silver.

Halfords paint is actually only certified to 80 degrees centigrade!! With hammerite to just shy of 400 degrees centigrade.
With the majority of brake calipers being made of aluminium to keep weight down you are looking at a melting temp of 659(.7) degrees centigrade meaning your calipers aren't going to get quite that close to the heat otherwise you risk catastrophic failure. Unless you are running a very costly uprated brake set which would most likely be a chromium with a melting point of 1960 degrees C you'll suffer brake fade far before you get near the hot temp of the standard setup!
well it all came down to what was in the paint store (black,white, gold,silver.) so had to be silver think it looks good.Lower said:Don't halfords still sell any branded caliper paint? I was thinking savage or G2.
Hammerite smooth data sheet gives a temperature limit of 80 degrees C and specifies it should not be applied to equipment that exceeds 150 degrees C. Where does your info come from?
Whilst the calipers themselves don't get up to the sort of temperature you make reference to, the discs do and radiate large amounts of heat.
Trials of DBA4000 discs with Ferodo DS2500 pads on my previous honda S2000 with heat paint on track showed the discs achieveing in excess of 650 degrees for in excess of 5 minutes. That was plenty hot enough to burn off the powder coat which will happily withstand 250 degrees C
