Centric 104.17800 Disc Brake Pad Set - Rear

Rear Brake Pads for Audi and Porsche

Centric Posi-Quiet Semi-Metallic Disc Brake Pad Set 104.17800 is built for rear brake service on select Audi and Porsche applications. It combines a semi-metallic friction formula with OE-style positive molding, precision-fit backing plates, and shims to support consistent braking performance and reduced noise.

Compatible With 2013-2020 Audi A6 Quattro, A7, A7 Quattro, A8 Quattro, RS7, S6, S7, S8 rear brake applications and 2015-2020 Porsche Macan rear brake applications. The Centric Posi-Quiet Semi-Metallic Disc Brake Pad Sets line focuses on fitment accuracy, controlled friction density, and faster break-in characteristics.

Key Features

• Semi-metallic friction material for rear disc brake service
• Positive-molded construction for even friction density across the pad
• Integrally molded friction attachment
• Precision cut or shaved backing plates for caliper fitment
• Mechanically attached shims to help reduce vibration-related noise
• Scorched friction surface to remove impurities and speed initial bedding
• Asbestos-free formulation
• Mounting hardware included where applicable
• Prepared for pad wear sensor use; pad wear sensor not included

Product Details

Centric 104.17800 is a rear disc brake pad set engineered around the Posi-Quiet product line’s OE-style manufacturing process. Positive molding compresses the friction material under high pressure so the pad maintains consistent density, which supports even wear and predictable pedal response over the service life of the pad. The semi-metallic compound is paired with shims and carefully finished backing plates to help control noise and vibration in everyday driving. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Rear brake squeal caused by pad vibration
• Uneven pad wear from inconsistent friction density
• Brake noise after pad replacement
• Extended break-in time after installation
• Fitment issues related to backing plate and caliper interface

Installation Notes

• Verify rear axle fitment before installation on Audi A6 Quattro, A7, A7 Quattro, A8 Quattro, RS7, S6, S7, S8, and Porsche Macan applications.
• Inspect rotors, caliper hardware, and guide pins before installing new pads.
• Use the included hardware where applicable and confirm shim placement during assembly.
• Follow proper bedding procedures after installation to establish stable friction transfer.
• Confirm pad wear sensor requirements for the vehicle, since the sensor is not included.

Quality Assurance

Centric manufactures the Posi-Quiet line using OE-style positive molding and adds a scorching process to help remove impurities and pre-burnish the friction surface. The result is a brake pad set built for consistent rear braking performance, controlled noise, and reliable fitment on the listed Audi and Porsche rear applications.
