Product Line Details: Unloaded Caliper w/Bracket

The Cardone Unloaded Caliper w/Bracket product line offers remanufactured calipers that come complete with the mounting bracket and necessary hardware kit, excluding mounting bolts. This design simplifies installation by providing all essential components except the bolts, ensuring a precise fit and proper function for specific vehicle applications such as the Mazda 3 series and CX-3. The phenolic piston material helps reduce heat transfer and corrosion, contributing to consistent brake performance.

Technical Description and Features

This Cardone 19-B7158 caliper features a single phenolic piston with an outer diameter of approximately 53.95 mm. The caliper’s oil emulsion finish in gray provides a protective layer against rust and environmental wear. Both the bleeder and inlet ports are sized M10x1.0, matching OEM specifications for proper brake fluid flow and maintenance. The included hardware kit contains all necessary components for mounting the caliper and bracket, though mounting bolts must be sourced separately. The caliper uses silicone grease on floating caliper mounting pins to ensure smooth operation and prevent squealing noises.
