That is correct. The sensor is effectively a destructive test. You only need to replace the one (or more) worn through on the end.

There is a pad spring kit but I keep reusing mine. Porsche recommends new caliper bolts when replacing the rotors, and I think rotor screws too.

Replace the worn sensor and zip tie them out of the way.

how many of you guys replace the caliper bolts when you do brakes???

i've done brakes on a lot of cars and never replaced this stuff... is this just BS to sell parts or do they really stretch/wear?

They really stretch. The large amount of torque spec'd - 63 Ft. Lbs. is fairly close to the limit of the Fastener material's elasticity. Replacing them is more a precautionary note, but still, it is possible they could fail if reused. It doesn't happen very often at all so reusing them at least once isn't that big a deal.

Reusing them repeatedly could cause an issue, but it's more likely the fastener, especially if slightly corroded, would break when trying to remove it rather than failing in use, though that too is possible. Then you're drilling and tapping or using an insert. The likelyhood of failure in a reused bolt is higher than one used only once.
