cciyu Rear Left & Right Disc Brake Caliper Set for Dodge & Jeep — 18B5046/18B5047, Includes Brackets & Hardware

These cciyu rear left and right disc brake calipers (18B5046 & 18B5047) are a direct-fit replacement set with brackets and hardware designed to restore rear braking performance on compatible Dodge and Jeep models.

If your vehicle is showing rear brake issues, replacing both left and right calipers with a matched set reduces uneven braking, sticking pistons, and fluid leaks. cciyu supplies a rear caliper assembly set that fits a variety of Dodge Nitro and Jeep Liberty and Wrangler model years; each caliper uses a single phenolic piston, M10 inlet and bleeder ports, and includes mounting brackets and installation hardware so you can swap parts without hunting for extra components.

Which vehicles will these calipers fit?

The cciyu rear caliper assemblies are built to match multiple model years and engine types. They fit late-2000s Dodge Nitro and a wide range of Jeep Liberty and Wrangler models including Wrangler JK and later model years listed in the fitment notes. Always confirm your vehicle details in the listing before ordering to ensure compatibility with specific drive types like 2WD, 4WD, or heavy-duty trims.

• Dodge Nitro: 2007–2011 (all engines)
• Jeep Liberty: 2008–2012 (all engines)
• Jeep Wrangler: 2007–2017 and Wrangler JK 2018 (all engines)
• Check part references: 18B5046, 18B5047 and OEM numbers listed

How are these calipers constructed to prevent leaks and noise?

cciYu uses thicker rubber sealing rings and precision-machined pistons to limit fluid loss and reduce piston wobble. The phenolic piston also helps minimize heat transfer compared with some metal pistons, lowering the chance of brake noise and helping consistent pad retraction.

• Thickened rubber seals for better fluid containment
• High-precision piston machining to reduce irregular movement
• Phenolic piston material for thermal stability and quieter operation

What technical specs should I know before purchasing?

These assemblies are specified for rear installation and come complete with brackets and installation hardware. Key dimensions include a 1.89-inch (48.01 mm) piston diameter and M10 x 1.0 ports for both the inlet and bleeder. They are single-piston calipers intended to match the referenced OEM part numbers for a straightforward replacement.

Still, confirm vehicle-specific notes (heavy-duty, drive type) and inspect hoses, pads, and rotors during replacement; some vehicles may need new brake hoses or pads if worn.
