cciyu Front Brake Calipers Pair — Left & Right (No Bracket), 66 mm Phenolic Piston, Hardware Included

cci yu front left and right disc brake calipers (184340 / 184339) are direct-replacement brake calipers designed to restore front braking performance for compatible Jeep models without requiring a bracket.

These calipers are engineered to meet or exceed original equipment specifications for a range of Jeep Cherokee, Grand Cherokee, Wrangler, Comanche, Wagoneer and Grand Wagoneer model years. Each unit comes as a front driver and passenger side pair, ships with installation hardware, and uses a single 66 mm phenolic piston with reinforced sealing to reduce fluid loss and noise. They are sold without mounting brackets, so confirm your vehicle’s bracket configuration before ordering.

Which vehicles do these calipers fit?

They are intended for many Jeep front-wheel applications across 1990–2006 model years; fitment varies by drive type (2WD, 4WD) and specific submodels. Use the vehicle selection on the product page to verify compatibility before purchase.

• Jeep Cherokee: 1990–1993 (including 4WD and RWD variants with two pad inspection holes)
• Jeep Grand Cherokee: 1993–1998 front caliper fit
• Jeep Wrangler/TJ: 1990–1995 and 1997–2006 model ranges
• Jeep Comanche and Wagoneer variants: selected years listed in product details

What are the key technical specifications?

Each caliper is a single-piston design built around a 66 mm (2.6 inch) phenolic piston and standard 3/8 x 24 thread ports for bleeder and inlet fittings. The assembly omits the mounting bracket but includes the necessary installation hardware to complete a direct swap where brackets are already present and compatible.

• Piston diameter: 66 mm (2.6 in), material: phenolic
• Bleeder port: 3/8 x 24; inlet port: 3/8 x 24
• Brake piston count: 1 per caliper; bracket: not included
• Installation hardware: included in the kit for bolt-on replacement

How do these calipers address leakage, noise, and longevity?

CCIYU calipers use thickened rubber sealing rings and high-precision piston machining to minimize brake fluid seepage and reduce vibration that can cause brake noise. While no part eliminates wear entirely, these design choices improve seal life and help maintain consistent pedal feel under normal driving conditions.

• Thickened rubber seals for improved fluid retention
• Precision-fit phenolic piston to reduce scoring and corrosion
• Manufactured to meet or exceed OEM tolerance for fit and function
• Sold as a matched left/right set for balanced front braking

Who is this for? These CCIYU front calipers suit owners and mechanics replacing worn, leaking, or damaged front brake calipers on supported Jeep models who already have compatible mounting brackets or prefer bracket reuse. They are appropriate for routine repairs and brake system refreshes where OEM-equivalent fitment, included hardware, and robust sealing are priorities. Always confirm year, model, and drivetrain before purchasing to ensure a correct match; if your vehicle uses heavy-duty or aftermarket brackets, verify clearance and mounting points prior to installation.
