Centric 106.07921 Disc Brake Pad Set - Rear

Centric Rear Brake Pads for Select GM and Cadillac

Centric Posi-Quiet Extended Wear Semi-Metallic Disc Brake Pad Sets are built for rear brake service on select Cadillac, Chevrolet, and GMC applications. Part number 106.07921 uses a semi-metallic friction formula, included wear sensor, and matched shims to support consistent braking performance and reduced pad noise.

Key Features

• Semi-metallic friction material for rear disc brake service
• Positive molding process for consistent friction density across the pad
• Integrally molded friction attachment for stable pad construction
• Precision-cut or shaved backing plates for caliper fitment
• Mechanically attached shims to help reduce vibration-related noise
• Scorched pads to remove impurities and speed initial break-in
• 4-pad set with 1 wear sensor included
• Mounting hardware included where applicable

Product Line Details

The Centric Posi-Quiet Extended Wear line focuses on OE-style pad construction with attention to fit, wear consistency, and noise control. For applications such as the Chevrolet Silverado 1500 rear brake pads, GMC Sierra 1500 rear brake pads, and Cadillac DTS rear brake pads, this line combines molded friction material with shims and prepared backing plates to support predictable pedal feel and even wear.

Detailed Description

Centric 106.07921 is a rear disc brake pad set engineered for vehicles that use a semi-metallic pad compound and a wear sensor. The pads are manufactured with a positive molding process similar to OE supplier methods, helping maintain uniform density through the friction material. That consistency supports even wear and stable braking characteristics over the life of the pads. The pads are also scorched to help clear impurities from the friction surface and shorten the break-in period after installation.

This part cross-references Wagner Brake MX792B and ZX792B for the same application. It is a direct-fit rear brake pad option for 2003-2007 Chevrolet Silverado 1500 rear brake service, 2003-2007 GMC Sierra 1500 rear brake service, and 2004-2011 Cadillac DTS rear brake service in the listed configurations.

What It Helps Address

• Brake noise caused by pad vibration
• Uneven pad wear from inconsistent friction density
• Longer break-in time after brake service
• Rear brake replacement on worn semi-metallic pads
• Wear sensor service needs on supported applications

Installation Notes and Tips

• Verify rear axle and caliper configuration before ordering, especially on Silverado 1500 and Sierra 1500 applications with GMT 800 disc brake calipers.
• Confirm the vehicle uses rear disc brakes and matches the listed year, make, model, and notes.
• Inspect rotors, caliper hardware, and guide pins during pad replacement.
• Use the included shims and wear sensor as specified for the application.
• Follow proper bedding procedures after installation to help establish consistent pad transfer.

Quality Assurance

Centric manufactures the Posi-Quiet line with OE-style positive molding, prepared backing plates, and attached shims to support consistent fit and performance. The friction material is asbestos free, and the pads are supplied with application-specific hardware where applicable.
