J.C. Whitney JC27150066 Front Left OEM Replacement Brake Caliper 6-Piston

The J.C. Whitney JC27150066 is a front driver-side (left-hand) disc brake caliper designed as a direct OEM replacement for the Cadillac CTS equipped with the factory 6-piston brake system. Engineered to restore original braking performance, this caliper delivers the precise hydraulic clamping force and stopping power that the vehicle was designed around.

Key Features:

• 6-Piston Design: Matches the factory multi-piston configuration for consistent, even brake pad pressure across the rotor surface
• Driver Side (Left-Hand): Correct-side fitment for the front left brake corner
• OEM Replacement: Direct drop-in fit with no modifications required — restores factory brake geometry and hydraulic specs
• Quality Construction: Built to meet or exceed original equipment specifications for durability and long service life
• Pressure Tested: J.C. Whitney brake calipers undergo hydraulic fatigue testing, pressure testing, and 100% leak testing before leaving the factory
• ISO 9001 / QS 9000 Manufactured: Production validated by automotive engineers to industry quality standards
• Backed by J.C. Whitney Warranty: Covered by J.C. Whitney's 1-year, unlimited-mileage warranty

When a sticking, leaking, or seized caliper compromises braking performance, replacing with the JC27150066 restores proper pedal feel, even braking, and safe stopping distances. Installation hardware is typically included — confirm contents at time of purchase. Always bleed the brake system after caliper replacement and bed in new brake pads per manufacturer recommendations.
