Product Details

DFC 4512-42085 is engineered as a rear brake service kit for 2007-2018 Jeep Wrangler and Jeep Wrangler JK models listed in the fitment data. The coated rotors are processed dry and ready to install, which helps reduce prep time during brake service. The rotor castings are machined to OE-style tolerances, finished for even pad contact, and inspected for balance and critical dimensions. The 5000 Advanced ceramic pads are formulated for stable friction performance and consistent stopping response, while the included hardware is designed to restore proper caliper movement and reduce brake noise caused by worn or corroded components.

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

What This Brake Kit Helps Address

• Rear brake noise from worn hardware or pad shims
• Uneven braking caused by fatigued or corroded brake components
• Rust buildup on exposed rotor surfaces
• Longer pedal response from worn rear pads and rotors
• Excessive caliper movement related to aged hardware
