Just spoken to MMC. Two brake master cylinder products are in the final stages of trialling before being confirmed as the fix. Cars with previously reported radiator issues will go to the factory to have the cooling system addressed at the same time as the braking system. A logistics firm called Acumen will be in contact with affected owners. My name and car were on the list from Williams. If you're affected, it may be worth confirming with your dealer that they've given MMC your most up to date contact details (MMC had the incorrect address for me). They're expecting to get cars into the factory from 18 July.
