The Rear Brake Caliper Frame R/L is a critical structural component of your vehicle’s rear disc braking system. It serves as the mounting foundation and rigid anchor point for the brake caliper itself. Precision-engineered from high-strength materials, this frame is responsible for holding the caliper in perfect alignment over the brake rotor, ensuring consistent and reliable braking force is applied.

When you press the brake pedal, hydraulic pressure forces the caliper pistons to clamp the brake pads against the rotor. The immense force generated during this action is transferred directly to the rear brake caliper frame. It must withstand significant shear and torsional stress without flexing or warping. Any compromise in its integrity, such as from wear, corrosion, or physical damage, can lead to caliper misalignment. This misalignment causes uneven pad wear, reduced braking efficiency, brake drag, vibration, and potential safety hazards.

This component is specified as "R/L," indicating it is often sold as a pair or is side-specific, meaning a left and right frame are designed for their respective positions on the vehicle. It is crucial to verify correct application for your specific make, model, and year. Installing a new or replacement rear brake caliper frame restores the essential solid mounting for the caliper, ensuring optimal pad-to-rotor contact, smooth operation, and the full restoration of your braking system’s performance and safety standards. Always ensure installation is performed with proper torque specifications.
