Keep the front brakes spinning true on your import with the Beck/Arnley Disc Brake Rotor 083-3631, a front-axle rotor that gives the brake pads the friction surface they clamp to slow the wheel. It's an application-specific fit for the 2017-2019 INFINITI QX30, 2013-2016 MERCEDES-BENZ B250, 2014-2019 MERCEDES-BENZ CLA250, and 2015-2020 MERCEDES-BENZ GLA250 (see the Buyer's Guide tab for engine-level detail).
This rotor is application-specific for the vehicles above and is sold individually. For even, balanced braking, replacing the rotors on both sides of the front axle together as a matched pair is recommended. If a worn, warped, or scored front rotor is behind pedal pulsation or reduced braking on your vehicle, this replaces it.

This part cross-references / interchanges with the following part numbers:
What is the Beck/Arnley 083-3631?
It's a front disc brake rotor — the machined disc the brake pads clamp against to slow the wheel. It's application-specific for the listed INFINITI and Mercedes-Benz models.
Which vehicles does this rotor fit?
It fits the 2017-2019 INFINITI QX30, 2013-2016 Mercedes-Benz B250, 2014-2019 Mercedes-Benz CLA250, and 2015-2020 Mercedes-Benz GLA250. Check the Buyer's Guide tab for engine-level detail.
Is it sold individually or do I get two?
This listing is for one rotor, sold individually. Replacing both front rotors together as a matched pair is recommended for even, balanced braking.
What does the high-carbon content do?
Per the manufacturer, the high-carbon content maximizes thermal conductivity, helping the rotor manage the heat generated during braking.
What are signs a front rotor may need replacing?
Pedal pulsation or steering-wheel shake when braking, reduced stopping ability, or visible scoring/grooves may signal a worn rotor. Diagnose the cause before replacing.
