Product Details

Part number 4512-48115 is engineered as a rear brake service solution for vans that see regular load, stop-and-go, and fleet use. The coated rotors help resist rust, while the ceramic pads are formulated for stable friction and quieter operation. The included hardware is designed to restore proper spring tension and caliper movement during brake service.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

• Rear brake noise from worn pads or fatigued hardware
• Uneven rear pad wear caused by corroded or weak hardware
• Rust buildup on exposed rotor surfaces
• Longer stopping distances from worn rear brake components
• Brake vibration related to rotor finish or pad condition
