Hi, Looking for recommendations to remediate a nagging problem on my XJR. I did the Brembo brake upgrade and got the Jaguar spec brake discs from British parts (UK). Less than 100 miles in and they have rust coating at the hub. Is there a specific coating or spray I can use to cure the problem for good? Never encountered anything like this before and would like to get it sorted ASAP.

 

Try a highest temp spray paint that you can find. I have used ACE Barbeque Black, good for 1000F (540C), on drum brakes on one of my cars and it held very well. This should be enough to withstand disc temperatures as well. I do not know whether they also have the same paint in grey or silver which, I guess, you would prefer
