Thanks for the reply I actually insulated my exhaust recently, so the temperatures wouldn't be as high as they were. I've become obsessed with keeping things cool in my engine bay after seeing how much of a difference wrapping the exhaust made, and thought that the brake lines might be suffering.
If I wrap things in aluminium, is it more likely to be keeping heat out or retaining it? eg i have wrapped the intake pipe in aluminium foil
thanks
