Rear Left Brake Caliper With Bracket for Sonata/Optima - Reliable Fit

In this review of the Rear Left Brake Caliper With Bracket (19B6457), the conclusion is straightforward: this unit is aimed at owners of 2011-2015 Hyundai Sonata and 2011-2015 Kia Optima who need a direct-fit replacement that balances cost and function. The reviewer found the caliper to be a practical choice because it matches OEM dimensions, uses an iron piston and standard M10 x 1.0 port sizes, and ships with the bracket needed for a rear driver side swap-making it a solid option for routine brake repairs when OE parts are not required.

Key Features

• Vehicle fitment: Direct fit for Hyundai Sonata L4 2.0L 2011-2014, Sonata L4 2.4L 2011-2015, and Kia Optima L4 2.4L 2011-2015 so buyers can expect correct alignment with stock mounting points.
• Complete package: Ships with the brake caliper and bracket (rear driver side) which reduces parts sourcing and simplifies installation for most DIYers and mechanics.
• Standard connections: Bleeder and inlet ports both use M10 x 1.0 threads, matching common brake hose and bleeder fittings to avoid unexpected adapters.
• Piston construction: Single iron piston with a 1.34 in diameter designed to deliver stable brake clamping force consistent with OEM style performance.
• Manufacturing control: Built to strict quality control standards and designed to meet or exceed OEM specifications for fit and function.

Who It's For

This caliper is best for owners of the specified Hyundai Sonata and Kia Optima model years who need a rear left replacement and want a unit that includes the bracket for a near plug-and-play swap. It appeals to independent mechanics, budget-conscious DIYers, and fleet maintenance teams replacing worn calipers without requiring dealer parts.

It is less suitable for those who require upgraded performance calipers, specialty finishes, or matched multi-piece kits with pads included. Buyers unsure about fitment should check the vehicle details carefully before purchase to avoid returns.
