    I would bet on contamination of either pads or disc, probably both. It's easy to get contamination from oily road surfaces. I transport my bike on a towbar rack and I always protect the discs with zip-lock sandwich bags.

    The discs can be cleaned with isopropyl alcohol (IPA) or any brake cleaner.

    Pads are harder to deal with and may be irrecoverable. But it's always worth a go. Remove the pads and rub each one in a circular fashion on a piece of sandpaper or emery cloth laid on a flat surface. 80 grit ought to be OK. It should not take long, keep blowing away the dust. The surface should look cleaner and no longer shiny.

    Refit the pads and bed in the brakes (see YouTube). This step is important!
