I had just replaced all my rotors and pads but the caliper mounting bolt I took off was not in usable condition, does anyone know which bolt size that is for a jaguar Xtype 2005 3.0. Rear I only need the bolt not the guide pins. Thanks

 

The rear brake caliper bolt part #'s are C2S9418, C2S46549 and C2S15593, depending on the VIN and top or bottom bolt.

If you have one good bolt, most autoparts stores can match the size and thread. Avoid generic hardware stores bolts, e.g., low carbon Grade 2. For brakes you want automotive grade, hardened steel bolts, e.g., Grade 8+ or Class 10.9+.
