Detailed Product Description

The Cardone 18-4991 is a remanufactured disc brake caliper engineered for Jeep Commander and Grand Cherokee vehicles. Featuring two phenolic pistons measuring 1.89 inches in diameter, this caliper provides consistent hydraulic pressure to the brake pads. The gray oil emulsion finish helps resist corrosion and extends the caliper’s service life. This unloaded caliper comes with a complete hardware kit, although mounting bolts are not included. The bleeder port size is M10x1.0, compatible with standard brake bleeding tools and procedures.

The phenolic piston material reduces heat transfer to the brake fluid, helping to maintain braking efficiency and reduce the risk of brake fade. This caliper is part of Cardone’s Unloaded Caliper line, which offers remanufactured calipers without brake pads, allowing for flexible brake system upgrades or replacements.
