I bought the Jag recently, and found ouut that my front bkakes were assembled from defferent parts. And the same "normal" part MJD7860AA is not compatible with the new 325 mm brake disks, but from the other side of the car, this paft fits perfectly.

Sorry for poor image quality, I deleted these pics, and how I had to restore them from my phone.

Here is the image of the MJD7860AA part. Here you can see it is a little thinner and the distance between bolt holes and the edges is different

My research says, that the 251 on the side is the identification that the carrier is for a 305 mm brake disc.

Jaguar doesn't sell the carriers individually but rather only in pairs.

I think that I have fount the answer.

I need MDJ786_1_AA, a caliper carrier for 325+ mm disks. If someone sells it, I would be glad to buy.
