| Fitment notes | Minimum thickness is 23.4 mm for the 305 mm disc and 26.4 mm for the 320 mm disc. None of the listed front discs are drilled, and Ferodo and Textar are not listed for this generation. The Ridex 82B1057 (320 x 28 mm, uncoated) is listed for cars built up to November 2016. |
A Genuinely Detailed, Real Root Cause Worth Knowing About "Warping" — Hyundai Tucson Brake Discs
If you've been told your discs have "warped" and are experiencing recurring vibration through the pedal, this is genuinely worth knowing: this has been documented as a widespread design issue affecting Hyundai and Kia models broadly, where the brake pads themselves can get stuck inside the caliper bracket rather than moving freely as intended. This causes uneven contact between the pad and disc, producing exactly the kind of vibration typically blamed on a "warped" disc — when the actual cause is the pad's restricted movement rather than the disc itself being physically distorted. A documented fix worth knowing about: lightly grinding down the small tabs (sometimes called "legs") on the back of the pad that sit inside the caliper bracket, and applying an appropriate brake grease to these contact points, allows the pad to move more freely and can resolve this recurring pattern rather than simply replacing discs repeatedly for the same underlying cause.
It's also worth knowing that rear discs commonly corrode more than the fronts on many cars, including Hyundai models, simply because the rear brakes experience less pressure during normal driving — meaning surface rust doesn't get worn away and cleared as effectively as it does on the harder-working front discs. This is a genuinely normal pattern rather than a sign of a specific rear-only fault.

Hyundai Tucson Brake Discs: The Part That Pads Depend On
On the Hyundai Tucson, 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.
Hyundai Tucson 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 Tucson typically use bigger discs than standard versions to handle the additional heat generated by more aggressive braking.
