Centric 104.16590 Disc Brake Pad Set - Rear

Centric Posi-Quiet Rear Brake Pads

Centric Posi-Quiet Semi-Metallic Disc Brake Pad Sets are built for consistent braking performance, even wear, and reduced noise. This Centric 104.16590 rear brake pad set uses a positive molding process and application-specific hardware details to support stable fitment in the caliper.

Compatible with select Cadillac ATS and Cadillac CTS rear brake applications, Centric 104.16590 is a practical choice for drivers looking for a semi-metallic disc brake pad set with OE-style manufacturing methods and noise-control features.

Key Features

• Semi-metallic friction material for balanced stopping performance
• Positive molded construction for consistent friction density
• Precision-cut or shaved backing plates for caliper fitment
• Mechanically attached shims to help reduce pad vibration noise
• Scorched friction surface to accelerate break-in
• Asbestos-free friction formulation
• Pad wear sensor included and prepared for wear sensor use
• Mounting hardware and pad shims included

Product Details

The Centric Posi-Quiet line focuses on brake pad consistency and noise control. Positive molding compresses the friction material under high pressure so the pad maintains uniform density across the surface, which helps support even wear over time. Centric also uses a scorching process to remove impurities from the friction material and pre-burnish the pad for a faster initial bedding period. The 104.16590 part number is a rear disc brake pad set for 2013-2019 Cadillac ATS and 2014-2019 Cadillac CTS rear brake service, including 2018-2019 Cadillac CTS rear applications with Brembo front calipers noted in the fitment data.

This part cross-references Raybestos Brakes EHT1659H for the same application.

What It Helps Address

• Brake squeal caused by pad vibration
• Uneven pad wear from inconsistent friction density
• Brake noise related to backing plate movement
• Longer initial break-in after pad replacement
• Rear brake service needs on Cadillac ATS and Cadillac CTS models

Installation Notes and Tips

• Verify rear fitment by year, model, and brake configuration before installation.
• Inspect caliper hardware, rotor condition, and sensor connections during brake service.
• Follow proper bedding procedures after installation to help stabilize friction transfer.
• Confirm the wear sensor routing and connector condition before final assembly.

Quality Assurance

Centric manufactures Posi-Quiet pads using OE-style positive molding and application-specific noise-control details. The friction material is asbestos free, and the pad design includes shims and hardware where applicable to support proper installation and consistent service performance.
