Designed with noise, vibration and harshness control in mind, the Akebono ProACT ACT863A rear brake pad set uses an OE-validated, application-specific ceramic formulation. It fits many vehicles, among them the 2007-2010 Hyundai Elantra, 1998-2009 Hyundai Sonata and 2001-2010 Kia Optima. See the "Vehicles it fits" section for the full list.
This rear kit comes from Akebono's ProACT Ultra-Premium line. Like other Akebono ProACT ultra premium ceramic brake pads, it pairs an application-specific ceramic formulation with precision-cut pressure plates and engineered chamfers and slots:
- OE-validated ceramic formulation: Each application gets its own OE-validated ceramic formulation.
- Precision-cut pressure plates: The pressure plates are precision-cut as part of the pad design.
- Engineered chamfers and slots: Scientifically engineered chamfers and slots are designed for braking performance and NVH control.
- Ceramic brake heritage: Akebono describes itself as the originator of ceramic brake technology and an original equipment brand installed on a wide range of vehicle models.
Akebono calls itself North America's leading supplier of advanced brake technology. It focuses its brake and friction material development on NVH analysis and control, backed by technical and R&D centers in Japan, the United States and France. When the rear pads are worn, this disc brake pad set is a direct-fit replacement for the listed applications, and these Akebono ProACT ceramic brake pads carry the same NVH-focused design.
Signs the rear pads may need replacing include squealing or grinding when braking, longer stopping distances, or pads worn thin at inspection.
