1 brake pad and 1 fastening screw
Whole brake
The whole brake (pad + holder) is available at the workshop of your Decathlon store (ref: 8366605).

It's really quite simple: unscrew the worn brake, put on the new one, screw the brake on... and you're done!
When should you replace your brake pad?
Change the front brake pad before the wear line is reached.
