Front Brake Caliper Temp

Would anyone know what temp - approx - the caliper slide mounting would get to under normal braking, in particular the slide pins?

I am guessing that they cant get too hot (not like the discs) due to the caliper mounting and parts being manufactured in aluminium - i have had a good look on the web and there are claims there that these can get up to between 200 - 300 degrees!? all be it on other cars but i cant see that (not under normal driving)

The reason for me asking - I have been given a tube of high temp red grease with teflon from a friend. This is motorbike formula and he uses it on his bike bearings / brakes / chain etc and swears by the stuff. It has a high temp melt point and i was going to give it a try on the slide pins on my Lex to see how it performed over a week. It seems to be slippy stuff but at the same time holds it's lubrication, is rubber seal friendly and is good against repelling water so i am thinking of giving it a go on my slider pins to see how it is.

I believe the grease is good up to around approx 130 degrees

Anyone with any info on the temperatures?

Sorry I know nothing about temperatures but in the past I have used copper grease which didn't last very long and I now use high temp moly which seems to last between services.

The stuff you have been given sounds like it will be up to the job so wouldn't hurt to try it.

I would just try and remove as much of the old grease as you can first.

Under Trackday conditions; you will reach those temperatures (it's very common to boil the brake fluid, if it hasn't been changed recently).
