Product Details

The DFC GEOSPEC Rotors with 5000 Advanced Brake Pads line is built around matched friction and rotor performance for modern brake service. The coated rotors resist rust better than conventional paint or zinc finishes, while the dry packaging eliminates the need to clean oil from the rotor before installation. The pads are formulated for consistent friction, with post-curing and scorching used to reduce initial break-in time and improve stopping response from the first stop. This kit is a practical choice for rear brake replacement on 2004-2008 Chevrolet Astra, rear and 2008 Saturn Astra, rear applications. Part number 4502-53020 is also a useful reference when ordering the correct rear brake kit for these vehicles.

What This Kit Helps Address

• Rear brake noise during stopping
• Rust buildup on exposed rotor surfaces
• Uneven or inconsistent rear braking feel
• Extended pad bed-in after brake service
• Brake vibration caused by worn rear rotors

Installation Notes

Compatible With 2004-2008 Chevrolet Astra, rear, including Mexico/TRW rear disc brake notes, and 2008 Saturn Astra, rear. Verify rotor size, caliper type, and rear disc brake configuration before installation. Clean the rotor friction surface only as needed during service; the protective coating is removed naturally by the brake pads during use. For search and ordering reference, this rear brake kit is identified by part number 4502-53020.

Quality Assurance

The rotors carry a 12-month warranty against defects in material and workmanship. The brake pads are post-cured, scorched, and assembled with premium shims to support consistent performance and NVH control.
