Designed for controlled rear braking with a focus on low noise and vibration, the Akebono ProACT ACT1391A is a rear disc brake pad set built around an OE-validated, application-specific ceramic formulation. It is listed as a direct-fit replacement for many models from Toyota and Lexus, among them the 2014-2019 Toyota Highlander, 2011-2020 Toyota Sienna and 2016-2020 Toyota Mirai.
These Akebono ProACT ultra premium ceramic brake pads pair their friction compound with several engineered design details:
- OE-validated ceramic formulation: an application-specific compound rather than a one-size-fits-all mix.
- Precision-cut pressure plates: part of the pad design Akebono uses for braking performance and NVH control.
- Engineered chamfers and slots: scientifically engineered to support braking performance and help control noise, vibration and harshness (NVH).
- Rear position: cataloged for the rear brakes on the listed applications.
Akebono Brake Corporation describes itself as the originator of ceramic brake technology. It is an original equipment brand installed on many models in total, with a focus on NVH analysis and control and technical and R&D centers in Japan, the United States and France.
If you are shopping for 2014-2019 Toyota Highlander rear brake pads, watch for signs that the pads may need replacing: squealing or grinding when braking, longer stopping distances, or friction material worn thin. Inspect the rotors when you change the pads. See the Buyer's Guide tab for the full list of vehicles and engine details.
