The reason behind replacing a brake pad carrier can be several. But in this case it was due to a broken brake caliper guide bolt where a small part of the bolt remained in the brake pad carrier (on which the brake caliper is mounted on). A quick and easy solution is to simply replace the entire brake pad carrier.
The brake pads and discs are a highly ordinary wear and tear spare part that needs to be replaced now and then. A good practice is to look over the condition of the brake pads and discs when for example changing tires in autumn and spring. Or if the warning light goes on, you should consider changing break pads (and brake discs if needed) in a quite near future.
