Wagner Brake PD961 Disc Brake Pad Set - Rear

Wagner ThermoQuiet PD961 Rear Brake Pads

Wagner Brake ThermoQuiet PD961 disc brake pads are built for rear applications that call for a ceramic friction formula, quiet operation, and OE-style fitment. This set uses zero-copper friction material and Integrally Molded Insulator (IMI) technology to help reduce brake noise on Subaru WRX STI, Subaru BRZ, Subaru Impreza, and Mitsubishi Lancer rear brake systems.

Key Features

• Ceramic friction material for consistent rear braking performance
• Zero-copper formulation
• Integrally Molded Insulator (IMI) technology for quieter operation
• Chamfered edges for smoother pad engagement
• Pad shims included
• Mechanical pad wear sensor included
• Outer and inner friction material thickness: 0.54
• FMSI number: 7859-D961

Product Details

The Wagner ThermoQuiet line focuses on quiet, clean braking with OE-style engineering. PD961 uses a ceramic friction compound and molded insulator design to help control vibration and noise at the rear axle. It is a direct-fit disc brake pad set for rear brake service on select Subaru and Mitsubishi applications, including 2020-2021 Subaru WRX STI rear, 2019-2020 Subaru BRZ rear, 2013-2019 Subaru WRX STI rear, 2017-2018 Subaru BRZ rear with Brembo Brake System and OE ceramic pads, 2004-2014 Subaru Impreza rear, and 2003-2006 Mitsubishi Lancer rear. This part cross-references Centric Parts 105.09610 and Raybestos Brakes PGD961M for the same application.

What It Helps Address

• Rear brake noise and squeal
• Brake vibration during light or moderate stops
• Worn rear pads requiring replacement
• Loss of consistent pedal feel from aged friction material
• Service needs on Subaru WRX STI, Subaru BRZ, Subaru Impreza, and Mitsubishi Lancer rear brake systems

Installation Notes

Verify rear axle fitment by year, model, and brake system before installation. Confirm the pad wear sensor style matches the vehicle’s original setup, and inspect rotors, caliper hardware, and guide pins for wear before reassembly. Because this PD961 set includes chamfered edges, shims, and a mechanical wear sensor, it is suited for a complete rear pad service on the listed applications.

Quality Assurance

Wagner Brake ThermoQuiet pads are engineered around a zero-copper ceramic friction formulation and IMI noise-control technology to support consistent, quiet rear braking. PD961 is built to meet the fitment and performance expectations of the listed OE-style applications.
