cciyu Front Disc Brake Calipers Pair (Left & Right) No Bracket — OEM-fit, 66mm Phenolic Pistons, Hardware Included

cci yu front left and right disc brake calipers (184340 & 184339) are direct-fit OEM-style replacement calipers engineered to restore front braking performance on compatible Jeep models without requiring a bracket.

These cci yu calipers are sold as a front pair (driver and passenger) and are built to match factory dimensions and mounting points for a straightforward install. Each caliper uses a single 66 mm phenolic piston, includes installation hardware, and features reinforced sealing to minimize brake fluid leakage. They replace part numbers such as 184340, 184339, 4883344, and related cross-references for a wide range of Jeep Cherokee, Grand Cherokee, Wrangler, Comanche and Wagoneer model years.

Will these calipers fit my Jeep model and drivetrain?

They are designed to fit many Jeep front applications from the early 1990s through the 2000s, but fit varies by year and drivetrain (2WD, 4WD, heavy-duty variants). Always verify fitment with your exact year, model, and whether your vehicle uses features like two pad inspection holes or special heavy-duty suspensions.

• Compatible with Cherokee 1990–1993, 1993–2001 ranges (specific trims vary)
• Fits Grand Cherokee 1993–1998 and Wagoneer/Grand Wagoneer model years noted
• Compatible with Wrangler/TJ ranges 1990–1995 and 1997–2006
• Check top-left vehicle selector on the product page before ordering

How are these calipers built to prevent fluid leaks and reduce noise?

cci yu calipers use thickened rubber seals and precision-machined phenolic pistons to maintain a reliable hydraulic seal and consistent piston travel. This combination helps reduce the risk of brake fluid seepage and unwanted brake noise, supporting smoother, more predictable braking action.

• High-precision piston machining for tight tolerances
• Reinforced rubber sealing rings to resist wear and leakage
• Phenolic piston material to reduce heat transfer and corrosion
• Designed to preserve factory braking geometry for consistent pad contact

What technical specs and hardware are included with the calipers?

Each package contains a front left and front right caliper, installation bolts and hardware needed for standard replacement, and bleeder/inlet ports sized 3/8" x 24. The calipers are single-piston units with a 2.6 inch (66 mm) piston diameter, matching many original equipment designs.

• Location: front left and right (driver & passenger)
• Piston diameter: 2.6 inch (66 mm); single phenolic piston per caliper
• Bleeder and inlet port size: 3/8" x 24 thread
• Installation hardware included; bracket not included

How easy is installation and what should I check before fitting?

These calipers are manufactured to OEM-style fitment for a direct swap in compatible vehicles, making installation straightforward for DIYers with basic brake tools or professional mechanics. Verify your vehicle year, model and drivetrain, inspect rotors and pads for wear, and ensure the brake lines and fittings match the 3/8" x 24 threads before beginning.

• Direct-fit design reduces modifications and adapter needs
• Includes hardware for standard bolt-on replacement
• Bracket is not supplied—use your existing caliper bracket
• Bleed brakes after installation to remove air and ensure firm pedal feel

Who this is for: This cci yu front caliper set is intended for Jeep owners, mechanics, and restoration shops that need an OEM-dimension replacement for front braking systems on compatible Cherokee, Grand Cherokee, Wrangler, Comanche, and Wagoneer models. It suits customers looking for reliable sealing, straightforward installation hardware, and a direct-fit alternative to original factory calipers—especially when restoring braking performance or replacing worn or leaking front calipers.
