Description
Product Overview
The A-Premium front brake caliper is engineered specifically for the 2003 Ford Explorer Sport and Explorer Sport Trac (2003‑2005). Constructed from high‑strength cast iron and finished with a premium anti‑rust coating, the caliper resists corrosion even in harsh climates. It incorporates a dual‑piston design that delivers even pressure distribution across the brake pad, improving modulation and reducing brake fade. The package includes the caliper, mounting bracket, phenolic pistons, and a complete set of installation hardware, matching the original equipment manufacturer (OEM) specifications for part numbers 18‑B4849, 3L2Z2B121AA, and related references. With a weight of 24.1 lb and compact dimensions of 15.5 × 11.32 × 6.75 in, the unit fits seamlessly into the factory‑designed caliper housing.
Usage
Designed for everyday driving, towing, and light off‑road conditions, this caliper excels in stop‑and‑go traffic as well as highway cruising. It is ideal for owners seeking a direct OE replacement that restores original braking feel after wear or damage. The anti‑rust coating extends service life, making it suitable for regions with road salt or high humidity. Installation is straightforward for experienced DIYers or professional mechanics; simply remove the old assembly, align the new bracket, and torque the hardware to factory specifications.
