High performance brake (if equipped)
As this vehicle is equipped with the high performance brake (large diameter brakes for enhanced braking performance), noise such as a squeal, squeak or groan is generated while braking.
This is normal and the friction may create circle patterns on the disc surface. This is also a normal situation which does not affect braking performance.

-
Frequent speeding and braking may deform components and wear the disc brake causing vibration when braking. Prevent brake damage by avoiding excessive braking.
-
Brake wear, noise, vibration from excessive braking or deformation of the brakes caused by repeatedly braking in high speed, racing on tracks, etc. can be excluded from warranty coverage.

-
Occasional brake noise is normal. If a continuous grinding or continuous squeal sound is present, the brake lining may be worn-out. Contact an authorized Kia dealer.
-
If the vehicle has continuous vibration or shudder in the steering wheel while braking, contact an authorized Kia dealer.
