Brake Cooling

[macaroni 17 1 Cars]

Hi,

I recently fitted some C5 "steelies" to my 205 and they look great, refurbed in Anthracite.

 

However, on track they totally over-heated the brakes! I am aware that is can be a problem with them and some people duct cold air to the brake rotors to compensate.

 

My question is this; is it possible over-cool brakes?

My track day pads need a little heat in them to be fully effective, so at the end of a long straight, will cooled brakes be too cool?

 

When I replaced the front wheels with standard 1.9 alloys, the problem went away and the braking was great from then on.

 

Incidentally, that swap also proved to me that Michelin Pilot Exalto 2s are a better track day tyre than Pilot Sport 3s.

 

Cheers,

 

Antony

I run vents in place of the fog lights and pipe cold air to the rotors - air ducting cable tied to the bottom arms and directed at the centre of the disc.

 

I haven't had any issues with over-cooling, and that's with standard 1.9 discs and callipers, Ferodo DS 3000 pads and running standard 1.9 wheels.

when did discs become "rotors"?

'Rotors' is American English, 'discs' is English English.

We use rotors and discs in Oz.

 

Im sure at a 'higher level' of motorsport there is an understood difference.
