J.C. Whitney JM27160012 OEM Replacement Rear Left Brake Caliper 1-Piston

The J.C. Whitney JM27160012 is an OEM replacement rear left (driver side) disc brake caliper designed as a direct-fit replacement for the Mazda Miata. Featuring a single-piston design, this caliper matches the factory specifications and dimensions of the original unit, ensuring a straightforward, bolt-on installation with no modifications required.

The rear brake caliper is a critical component of your vehicle's disc brake system. It houses the piston and brake pads, applying clamping force to the rotor when hydraulic pressure is transmitted from the master cylinder, converting that pressure into reliable stopping power.

Key Features:

• Direct OEM Replacement: Matches original factory dimensions and specifications for a hassle-free installation
• Single-Piston Design: 1-piston configuration consistent with the Mazda Miata factory rear brake setup
• Driver Side (Left Rear): Designed specifically for the left/driver-side rear position
• New Construction: Supplied as a new unit — not rebuilt or remanufactured
• Hydraulic Compatibility: Engineered to work within the Miata's standard brake hydraulic system

This caliper is compatible with 1990–2005 Mazda Miata models equipped with standard (non-sport) rear brake suspension. It is sold as a single caliper for the left rear position.
