Centric 104.13620 Disc Brake Pad Set - Rear

Centric Posi-Quiet Rear Brake Pads

Centric Posi-Quiet Semi-Metallic Disc Brake Pad Set 104.13620 is built for rear brake service on select Saturn Astra and Chevrolet Astra applications. It combines semi-metallic friction with OE-style positive molding to support consistent braking feel, even wear, and stable performance over the life of the pad.

The Posi-Quiet line focuses on fit, noise control, and break-in consistency. For rear brake pad replacement on a 2008-2009 Saturn Astra or a 2000-2008 Chevrolet Astra with Lucas-TRW calipers, this pad set uses precision backing plate details, attached shims, and a scorching process to help reduce vibration-related noise and speed up initial bedding.

Product Details

Centric’s Posi-Quiet brake pad line is engineered using a molding process commonly used by OE suppliers, helping the friction material bond evenly to the backing plate. That construction supports uniform contact, predictable pedal response, and balanced wear. The pads also feature precision-cut or shaved backing plates and mechanically attached shims to improve caliper fitment and reduce brake squeal.

Part number 104.13620 is a direct-fit rear disc brake pad set for 2008-2009 Saturn Astra and 2000-2008 Chevrolet Astra models equipped with Lucas-TRW calipers. This part cross-references Wagner Brake MX1362 and Monroe Shocks & Struts 172286 for the same application.

Common Brake Issues It Can Address

• Rear brake squeal or vibration noise
• Uneven pad wear from inconsistent friction density
• Poor initial brake feel after pad replacement
• Fitment concerns at the caliper interface
• Brake dust and performance inconsistency from worn rear pads

Installation Notes

Verify rear caliper type before installation, especially on Chevrolet Astra applications with Lucas-TRW calipers. Inspect rotors, caliper slides, and hardware condition during service, and clean all mating surfaces before fitting the pads. The included shims and hardware should be installed as supplied to support proper pad seating and noise control. Follow standard brake bedding procedures after installation to help the friction material settle in correctly.

Quality Assurance

Centric manufactures Posi-Quiet pads with OE-style positive molding and a scorching process that removes impurities from the friction material and pre-burnishes the pad surface for faster break-in. The formulation is asbestos free and built with noise-reduction details intended to support consistent rear brake performance on compatible Saturn Astra and Chevrolet Astra applications.
