Detailed Description

Nugeon 99-02863B is a remanufactured front left brake caliper engineered for select Mercedes-Benz SUVs and crossovers, including 2016-2019 Mercedes-Benz GLE400, 2017-2019 GLS450, 2016-2018 GLE350, 2016 GL350, 2013-2016 GL450, 2016 GLE300d, 2013-2015 GL350, 2015 ML250, 2012-2015 ML350, and 2015 ML400. This part number is built around the original application requirements, including the supplied mounting bracket and the specified inlet and bleeder thread sizes.

As a remanufactured brake caliper, 99-02863B is intended to restore hydraulic clamping performance at the front left wheel. The phenolic pistons, dust boots, and rust-preventative finish support brake service on vehicles where caliper wear, sticking, or leakage has affected braking consistency. If you are sourcing a Mercedes-Benz GLE400 front left brake caliper or a Mercedes-Benz GLS450 front left caliper replacement, this unit matches the listed fitment and hardware configuration.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Brake fluid leakage from a worn caliper body or seal area
• Uneven front brake pad wear caused by caliper sticking
• Reduced braking response from a failing hydraulic caliper assembly
• Corrosion-related caliper seizure on the front left corner
• Noise or drag associated with worn caliper slides or hardware

Installation Notes and Tips

Install 99-02863B only on the listed front left Mercedes-Benz applications and verify bracket, inlet, and bleeder thread sizes before assembly. Bleeder screw, caliper slides, dust boots, and brake pad installation hardware are included; pads are not included. Use the correct brake fluid, torque fasteners to factory specifications, and bleed the hydraulic system thoroughly after installation. Inspect the rotor, pads, and brake hose condition before returning the vehicle to service.

Quality Assurance

This Nugeon remanufactured caliper is rebuilt for brake service applications and finished with rust prevention to support long-term use in the brake hydraulic system. The aluminum housing, phenolic pistons, and included service hardware reflect the application-specific design required for the listed Mercedes-Benz fitments.
