Quiet your hybrid's front brakes with the Wagner ThermoQuiet Disc Brake Pad Set QC1184A. This ceramic front pad set installs as a direct-fit replacement for the listed applications: the 2010-2015 Toyota Prius, 2011-2017 Lexus CT200h, and 2012-2015 Toyota Prius Plug-In (All engines). It replaces the worn front friction on the front axle to help restore normal braking when the original pads are worn.
- Quieter operation: Wagner's IMI technology integrates the friction material, backing plate, and insulator into a one-piece pad for select applications, while the laser-shaped friction surface spreads heat, sound, and vibration to reduce noise for everyday street driving.
- Zero-copper ceramic: Uses the Wagner OE25 zero-copper ceramic friction formulation for low, light-colored dust and cleaner wheels compared with conventional semi-metallic pads.
- Long-life design: The formulation is designed to dissipate heat for consistent, long-lasting friction performance during normal daily driving.
- Noise-reducing details: Slotted and chamfered edges; pad shims and abutment clips are included, and premium stainless-steel hardware is included for select applications. A pad wear sensor is not included.
Signs the front pads may need replacing include squealing, grinding, or reduced braking feel. FMSI 8538-D1184. Inspect the rotors and replace pads on both front wheels together for even, balanced braking.
