Lexus CT200h Brake Discs: The Part That Pads Depend On
On the Lexus CT200h, 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.

Lexus CT200h 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 CT200h 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 Persistent Vibration — Lexus CT200h Brake Discs
If a vibration under braking has survived multiple rotor replacements, this is genuinely worth knowing: documented cases on related Lexus models describe continuous brake vibration persisting for years despite repeated rotor, pad, and even caliper replacements — worth knowing that repeatedly replacing the same parts isn't guaranteed to resolve the fault if the actual root cause lies elsewhere.
It's also genuinely worth knowing that if a fresh replacement disc shows the identical fault from the very start, the disc itself likely isn't the actual cause, and it's worth cleaning the mating faces between the hub, disc, and wheel thoroughly before assuming a disc is warped.
