Land Rover Discovery Brake Discs: The Part That Pads Depend On
On the Land Rover Discovery, it's a paired system: let either one wear too far and the other suffers for it, which is why so many "just a pad change" jobs end up including discs once a mechanic actually looks.

Land Rover Discovery Brake Discs: What They Do
Brake discs provide the surface the brake pads clamp against to slow the car, converting momentum into heat through friction. Larger, sportier trims of the Discovery typically use bigger discs than standard versions to handle the additional heat generated by more aggressive braking.

A Genuinely Useful Piece of Context Worth Knowing About Brake Vibration — Land Rover Discovery Brake Discs
If a vibration under braking has been diagnosed as warped discs, this is genuinely worth knowing: documented cases on related Land Rover models describe a persistent vibration actually traced to brake pads fitted backwards rather than genuinely warped discs, since pads are directional — worth confirming this before assuming the discs themselves are at fault.
It's also genuinely worth knowing a useful alternative cause worth checking: an axle seal leaking oil or grease directly onto the disc surface can produce vibration symptoms very similar to genuinely warped discs.
