Detailed Description

PowerStop L5544 is engineered as a direct OE-style rear brake caliper replacement for vehicles including the 2018-2022 Chevrolet Equinox rear left, 2018-2022 GMC Terrain rear left, 2016-2021 Chevrolet Malibu rear right, 2018-2020 Buick Regal Sportback rear left and rear right, 2018-2020 Buick Regal TourX rear right, 2019-2020 Cadillac XT4 rear right, and 2017-2019 Buick LaCrosse rear right. It is also listed for 2023-2024 Chevrolet Equinox rear left, 2023-2024 GMC Terrain rear left, and 2023 Chevrolet Malibu rear right, with notes for power-operated parking brake applications where specified.

Each caliper is pressure tested to verify piston movement and check for leaks before it leaves the remanufacturing process. The result is a replacement brake caliper built around the original mounting points and hydraulic connections, making it a practical choice for rear brake service on Chevrolet Malibu, Chevrolet Equinox, GMC Terrain, and other listed vehicles. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Caliper Helps Address

• Rear brake drag caused by a sticking piston or slide issue
• Brake fluid leakage at the caliper body or bleeder area
• Uneven rear pad wear from worn caliper hardware
• Reduced braking response from a failing rear hydraulic caliper
• Corrosion-related caliper seizure on daily-driven vehicles

Installation Notes and Tips

Verify the rear position and side before installation, since this part is listed for rear left and rear right applications depending on vehicle fitment. Confirm the inlet and bleeder thread sizes match the original brake line and service hardware, and inspect pads, rotors, and brake hoses during caliper replacement. Bleeding the brake system after installation is required to restore proper pedal feel.

For fitment-specific service, confirm the application against the vehicle year, make, model, and rear position before ordering. L5544 is a direct replacement for the listed OE-style rear caliper applications on Chevrolet Equinox, GMC Terrain, and related GM platforms.

Quality Assurance

PowerStop remanufactures the caliper and bracket in its Chicago, IL facility and pressure tests each unit to help verify piston operation and leak resistance. New seals, slide pins where applicable, dust boots, bleeder screws, and stainless steel pad abutment clips are used during assembly to support consistent brake service quality.
