J.C. Whitney SET-JM27160011 Rear Brake Caliper Kit OEM Replacement 2-Wheel Set

The J.C. Whitney SET-JM27160011 is a complete rear brake caliper replacement kit designed as an OEM-style replacement for the Mazda Miata (1990–2005 NA/NB generations). This two-wheel set includes a pair of rear brake calipers, giving you everything needed to restore proper rear braking function in a single purchase.

Brake calipers are a critical hydraulic component of the disc brake system, responsible for clamping the brake pads against the rotor to generate stopping force. Over time, caliper pistons, seals, and housings can corrode or seize—especially on vehicles of this age—leading to uneven braking, brake drag, or fluid leaks. Replacing the calipers as a complete pair ensures balanced braking performance across both rear wheels.

Key Features:

• OEM-replacement rear brake calipers engineered to match original specifications
• Complete 2-wheel set — includes (2) rear brake calipers
• Direct-fit design for straightforward installation without modifications
• Restores proper hydraulic clamping force and braking balance
• Designed for standard (non-sport) rear brake configurations on 1990–2005 Miata NA/NB models

This kit is ideal for restoring stock braking performance on aging Miata platforms. As a complete pair, it supports a proper brake service that maintains equal hydraulic pressure and wear on both sides of the rear axle.
