Disc brakes absolutely do not wear oil/fat. One, two small splashes from a chain cleaner, which is always somewhat fat-containing, can be sufficient that a disc brake only still squeaks and no longer brakes meaningfully.

You can clean the pane: demonting, 2-3 passages through the dish sink, then wet a few times alternately with brake cleaner and rub off with a clean cloth… until this cloth remains clean.

The brake pads are usually not to be saved and must be replaced. You can try to “burn” it by placing it outside (!) on a refractory and heat-resistant base (e.g. paving stones) and working for 10 minutes with a hot air blower or a weed flame. With luck, you can slow them down again and the brake works again normally. If that doesn’t work, you have to replace them.

And clean the pane thoroughly. And after mounting both parts, brake the brake again.

Next time you think to protect the brake from splashes 😉

You’re missing the rear brake. You have an additional siren on the bike.

Sure, the rear brake is not so important for short braking distances. But if the front should have some problem, it’s good if you have a second brake.
