Having a clear out of the garage and came across 7 x CCC5644. Obviously a parts ordering ****-up in the past sometime.

CCC5644 is the little clip on the handbrake cable at the hub. See 23 on this diagram

Handbrake Assembly and Cables - Parts For XJ Series from (V)720125 to (V)812255 (X300) | Jaguar Classic Parts UK

These are no longer available from Jaguar so I may have the entire world stock

I'm keeping two just in case, so there are 5 available for free. PM me your address and I'll send. You can donate what it costs me to post them to a local charity on my behalf. Deal?

(BTW I think these also fit XJ40, XJ8 and XJS (with outboard discs))

 

Reassembled my rear disc the other day but this clip had broke . Not even sure exactly where it locates but I think it may be critical to the handbrake operation? .
