Quiet, low-dust rear braking for everyday driving — the Wagner ThermoQuiet Ceramic Disc Brake Pad Set QC1878 is a rear-axle set built to deliver smooth, consistent stops. It installs as a direct-fit replacement for the listed applications: the 2019-2023 Acura RDX [All] and the 2016-2025 Honda Civic [All].
Wagner's TQ ceramic pads use the OE25 zero-copper friction formulation and the Integrally Molded Insulator (IMI) one-piece design, which bonds the friction material, backing plate and insulator together for quieter operation on select applications. An application-specific, laser-shaped friction surface helps spread out heat, sound and vibration to reduce noise, and the formulation is designed to dissipate heat for durable friction performance and reduced brake fade.
- Cleaner wheels: ceramic friction produces less visible dust than semi-metallic pads and helps reduce rotor wear.
- Quiet, smooth feel: engineered for whisper-quiet, consistent stops during everyday street driving.
- Hardware included: premium abutment clips and pad shims are included, along with a mechanical pad wear sensor.
- Slotted, ceramic construction with a zero-copper (OE25) formulation.

Are these front or rear brake pads?
This is a rear disc brake pad set. It replaces the rear pads on the covered Acura RDX and Honda Civic applications.
What are the benefits of ceramic pads?
Ceramic pads like these run quieter and produce less visible dust than semi-metallic pads, with a smooth, consistent pedal feel during everyday street driving.
Does this set include hardware and a wear sensor?
Yes. It includes abutment clips, pad shims, and a mechanical pad wear sensor for the covered applications.
How many sets do I need?
One set covers your rear axle (both wheels). For even, balanced braking it's best practice to replace both sides together and inspect the rotors.
