This Skoda Fabia came in with noisy brakes. A straightforward replacement of brake discs and pads.
Very rarely nowadays, unless the brake discs are in very good condition, would you replace just the brake pads on any car. It makes the job so much more professional, and will cost less in the long run, to replace them all as a matching set and less likely for the brakes to start squeaking after a few thousand miles of driving.
If you just replace the pads with worn discs the new pads will wear very quickly and before you know it you will require another set of brake pads.
It also means that the new pads will 'bed in' well with the new discs
