Ordered from rockauto.com
Better prices than Jag suppliers.
Ceramic pads not listed by XKs Unlimited.
I like the ceramics because I'm very happy with the pedal pressure for my front Centric Ceramics.


Addendum: Combination of 3/4" master cyl, 4-piston Toyota calipers and Centric ceramic pads fore-and-aft -- booster unnecessary.
