Product Details

Centric’s Posi-Quiet Extended Wear line focuses on fit, noise control, and predictable wear. This brake pad set uses an integrally molded friction attachment and includes pad shims to support quieter operation. The positive molding process compresses the friction material under high pressure, helping maintain even density for more uniform braking performance over the life of the pad. The added scorching process helps condition the friction surface before installation, which can shorten the initial break-in period.

Part number 106.09990 is a rear disc brake pad set for select Chevrolet Impala and Impala Limited models, Buick Allure and LaCrosse models, and Pontiac Grand Prix models. This part cross-references Wagner Brake SX999 for the same application.

What It Helps Address

• Brake squeal caused by pad vibration
• Uneven pad wear from inconsistent friction density
• Longer initial break-in after brake service
• Reduced braking consistency from worn rear pads
• Fitment issues related to backing plate and shim design

Installation Notes

Verify rear axle fitment before ordering. This set is prepared for pad wear sensor use and includes a wear sensor where applicable. Inspect caliper hardware, rotor condition, and guide pins during service to help ensure proper pad movement and even contact. Confirm the hardware kit number 117.62049 when matching service components for this application.
