J.C. Whitney SET-JC27160027 Rear Brake Caliper Kit 2-Wheel Set OEM Replacement

The J.C. Whitney SET-JC27160027 is a complete rear brake caliper kit designed as a direct OEM replacement for the Chevrolet Trailblazer (2002–2009) and Trailblazer EXT (2002–2006). This two-wheel set includes two rear brake calipers — one for the driver side and one for the passenger side — providing everything needed to restore proper rear braking function to factory specifications.

Key Features:

• Complete 2-Wheel Set: Includes (2) rear brake calipers for a full axle replacement
• OEM Replacement Design: Engineered to match original factory fit and function for a direct bolt-on installation
• Single-Piston Rear Caliper: Features a single-piston design consistent with the factory rear brake configuration on the GMT 360 platform
• Piston Diameter: 1.89 inches (48.1 mm) — matching OEM specifications
• Inlet & Bleeder Port Size: M10 x 1.0 for compatibility with the factory brake hydraulic system
• Restores Stopping Power: Replaces worn, seized, or leaking calipers to ensure reliable hydraulic actuation and smooth brake modulation

The Trailblazer rear brake system uses a single-piston caliper with the parking/emergency brake integrated into the rotor hat. Replacing faulty calipers is essential to preventing brake pad drag, maintaining proper pedal feel, and ensuring safe, controlled stopping. Professional installation is recommended. Brake bleeding will be required after installation.
