Rear Left Brake Caliper Assembly w/Bracket 18B5043 - Reliable Fit

In this review the rear left brake caliper assembly with bracket (18B5043) is evaluated for drivers who need a direct-fit replacement for certain Ford, Lincoln and Mazda models. The bottom line: this caliper is aimed at anyone seeking a durable, OEM-style replacement that restores braking stability without fuss. It stands out because it matches factory mounting and fluid port sizes while promising quieter operation, making it a practical choice for owners who want a dependable, easy-to-install repair rather than a performance upgrade.

Key Features

• Direct Vehicle Fitment: Designed specifically for 2007-2010 Ford Edge 3.5L and Lincoln MKX 3.5L and 2007-2012 Mazda CX-7 2.3L/2.5L, so buyers can expect correct alignment and mounting.
• Exact Port Sizes: The caliper uses M10 x 1.0 for both the bleeder and inlet ports, which helps ensure compatibility with stock brake lines and bleeder fittings.
• Durable Piston Material: The single iron piston and 1.68 in diameter offer robust braking surface and resistance to wear for long-term service life.
• Bracket Included: Ships with the bracket (18B5043/18-B5043 rear driver side) so the unit arrives ready for installation and reduces the need to swap parts from the old caliper.
• Quiet Operation: Manufactured to reduce squeal and harsh noises for a quieter, more comfortable driving experience after replacement.
• OEM Standard Quality: Built to strict control standards to meet or exceed OEM specifications for consistent brake power output and safety.

Who It's For

This caliper is best for owners of 2007-2010 Ford Edge and Lincoln MKX vehicles and 2007-2012 Mazda CX-7 models who need a reliable rear left driver side replacement that restores original braking function. It suits DIY mechanics and independent shops because it comes with the bracket and matches stock port threads and piston size, simplifying installation.

It is not intended for drivers seeking high-performance or track-focused upgrades; those buyers should look for performance calipers or multi-piston options. Also, anyone with vehicles outside the listed fitment should verify compatibility before purchase.
