Centric 105.18980 Disc Brake Pad Set - Rear

Centric Posi-Quiet Rear Brake Pads

Centric Posi-Quiet Ceramic Disc Brake Pad Set 105.18980 is built for rear brake service on select Audi applications, including Audi A4, A5, A6, and Q5 models. This Centric brake pad set uses a ceramic friction formula and OE-style positive molding to promote consistent pedal feel, even wear, and stable braking performance.

The Posi-Quiet line focuses on fit, noise control, and break-in consistency. For rear brake pad replacement on Audi A4 Quattro, Audi A5 Sportback, or Audi Q5 rear brake systems, part number 105.18980 provides a direct-fit solution with the details needed for clean caliper engagement and reduced vibration.

Key Features

• Ceramic friction material for smooth, quiet braking performance
• Positive-molded construction for uniform density across the pad surface
• Integrally molded friction attachment for consistent backing plate bonding
• Pad shims included to help reduce brake noise and vibration
• Prepared for pad wear sensor applications
• Precision-cut or shaved backing plate details for caliper fitment
• Scorched friction surface to help accelerate initial break-in
• Asbestos-free formulation

Posi-Quiet Product Line Details

Centric Posi-Quiet Ceramic Disc Brake Pad Sets are engineered with OE-style manufacturing methods and application-specific friction compounds. The line is focused on consistent density, controlled wear, and reduced noise through features such as mechanically attached shims and carefully finished backing plates. Part number 105.18980 follows that approach for rear brake service on select Audi vehicles.

Detailed Description

Centric 105.18980 is a rear disc brake pad set for select 2016-2021 Audi fitments, including Audi A4, A4 Quattro, A4 allroad, A5, A5 Quattro, A5 Sportback, A6 Quattro, A6 allroad, A7 Sportback, Q5, Q5 PHEV, and Q5 Sportback applications listed below. The ceramic friction material is paired with shims and an integrally molded attachment method to support stable braking response and help control common pad noise concerns. The positive molding process used in this Centric brake pad set helps maintain even friction density, while the scorching process helps remove impurities and pre-condition the pad surface for quicker bedding.

This part cross-references Centric Parts 301.18980 for the same application.

What It Helps Address

• Rear brake squeal during normal stop-and-go driving
• Brake vibration caused by pad movement in the caliper
• Uneven pad wear from inconsistent friction density
• Extended break-in time after rear brake pad replacement
• Loss of braking smoothness on Audi rear disc brake systems

Installation Notes and Tips

• Verify rear axle fitment by year, model, and notes before ordering.
• Inspect caliper hardware, rotors, and guide components during pad replacement.
• Clean the caliper bracket and pad contact points before installation.
• Follow the vehicle-specific bedding procedure after installation to help establish proper pad transfer.
• Confirm wear sensor requirements, since this pad set is prepared for a sensor but does not include one.

Quality Assurance

Centric manufactures the Posi-Quiet line using OE-style positive molding and application-focused friction design. The pad surface is scorched during production to help improve consistency at installation, and the ceramic formulation is asbestos free. Part number 105.18980 is built for rear brake service on the Audi applications listed in the fitment data.
