Do I need to refurb my calipers?

[TheArchitect]

Hi guys

Whilst working on the car last weekend I noticed my new discs (6 months) have rust around the outside edge in the inside faces. About 1 cm.

Should I get the calipers refurbished? It's not something I'm happy doing myself so will send them to someone like biggred.

Cheers

Are they sliding calipers? If so check and lube the pins the calipers slide on 1st.
