cciyu Rear Left & Right Disc Brake Caliper Pair for Dodge & Jeep – 18B5046/18B5047 with Brackets & Hardware

cciYu rear left and right disc brake calipers with brackets (18B5046 / 18B5047) are direct-fit replacement assemblies designed to restore rear braking performance on select Dodge and Jeep models.

These paired calipers arrive as a complete rear assembly (driver and passenger) and include brackets and installation hardware so you can replace worn units without sourcing extra parts. Built to match OEM specifications, the set is compatible with a range of Dodge Nitro and Jeep Liberty and Wrangler model years; it uses a single phenolic piston per caliper and M10 x 1.0 fluid ports for easy integration into stock brake lines.

Which vehicles do these calipers fit?

The cciYu rear caliper assemblies are listed for multiple Dodge and Jeep models across several years. Fitment covers both rear driver and passenger sides and supports all engine variants for the specified years. Always verify your exact vehicle configuration (including Heavy-Duty, 2WD, 4WD, or AWD) before ordering to ensure compatibility.

• Dodge Nitro: 2007–2011 (all engines)
• Jeep Liberty: 2008–2012 (all engines)
• Jeep Wrangler: 2007–2017 (all engines)
• Jeep Wrangler JK: 2018 (all engines)

What are the key specifications of the caliper assemblies?

Each caliper in the pair features a single piston made of phenolic material and a piston diameter of 1.89 inches (48.01 mm). Fluid inlet and bleeder threads are M10 x 1.0, and the assemblies ship with brake caliper brackets and the necessary installation hardware for a straightforward replacement. Reference numbers and OEM cross-references are provided for part matching.

• Location: Rear left & right calipers
• Piston: 1 piston per caliper, phenolic material, 48.01 mm diameter
• Ports: Bleeder and inlet port sizes M10 x 1.0
• Included: Bracket and installation hardware
• Reference numbers: 18B5046, 18B5047 and cross-references listed

How do these calipers address leakage and noise concerns?

The assemblies use reinforced rubber sealing rings and precision-machined pistons engineered to limit fluid seepage at the piston seal area. Reduced leakage helps maintain consistent brake fluid pressure and avoids the intermittent noises that can come from contaminated or worn seals. Properly sealed calipers also simplify maintenance by lowering the frequency of brake fluid topping-up.

• Thickened rubber sealing rings to reduce fluid seepage
• High-precision pistons to ensure even sealing and movement
• Designed to minimize abnormal braking noise related to leakage

What should I know before installing these calipers?

These cciYu calipers are manufactured to meet or exceed OEM specifications and arrive with brackets and hardware to support a near-direct replacement, but you should still confirm fitment using your exact vehicle details. Bleed the brake system after installation and check for proper torque on mounting hardware. If your vehicle has unique trim levels or factory-installed heavy-duty braking options, compare the listed references and dimensions to your original parts.

• Confirm vehicle year, model, drivetrain (2WD/4WD/AWD) before purchase
• Bleed brakes and inspect lines after installation
• Compare reference numbers (e.g., 68003705AA, 68003774AA) with OEM part
