Rear Left Brake Caliper Assembly 18-4678 for Ford & Lincoln - Quiet

In this review of the Rear Left Brake Caliper Assembly 18-4678, the bottom line is straightforward: this caliper is for owners who need a direct-fit, reliable rear driver side replacement for late 1990s and 2000s Ford and Lincoln trucks and SUVs. The reviewer found the single biggest reason to buy is its consistent braking performance that meets or exceeds OEM specifications, producing quiet operation without the high-pitched screeching some worn calipers make. Installation is direct for the listed vehicles and it ships as a single caliper without the mounting bracket.

Key Features

• Vehicle Fitment: Designed to fit a wide range of models including Ford Expedition, F-150, F-150 Heritage, F-250 and Lincoln Blackwood, Navigator, and Town Car, which simplifies parts selection for those years.
• Brake Piston Material: Uses a phenolic piston to resist heat transfer and reduce corrosion, helping maintain brake performance over time.
• Piston Size and Count: A single 2.01 in piston provides predictable pressure on the pad for stable stopping force on the rear left wheel.
• Port Sizes: Includes standard 3/8-24-UNF bleeder and inlet ports for straightforward brake line and bleed fitting during service.
• Quiet Operation: Engineered to minimize annoying screeching sounds under braking, leading to a more comfortable driving experience.
• Quality Control: Built to strict standards to meet or exceed OEM specifications, delivering consistent braking performance expected from replacement calipers.

Who It's For

This caliper suits owners and DIY mechanics who drive the covered Ford and Lincoln models from 1997 through 2011 and need a direct replacement for the rear left/driver side. It is particularly useful for those who value quiet operation and a part that adheres to OEM fit and function, making it a practical option for routine brake service.

It is less appropriate for buyers who require a complete assembly with bracket or who need both left and right calipers and pads included in one kit. Also, those seeking a remanufactured caliper with refurbished hardware should confirm included components before purchase since this product ships as one caliper without the bracket.
