Help quiet noisy, worn rear brakes with the Bosch QuietCast Disc Brake Pad Set BC1646 — a BOSCH brake pad set for the rear axle that installs as a direct-fit replacement for the listed applications. It fits many vehicles, among them the 2015-2020 Mercedes-Benz GLA250, 2017-2020 Mercedes-Benz SLC300 and 2014-2019 Mercedes-Benz CLA250. These BOSCH QuietCast brake pads carry Bosch's OE braking heritage dating back to 1927 and use a patented copper-free friction formula compliant with 2025 Copper Free legislation.
Signs your rear pads may need replacing include squealing, grinding, reduced braking response, or a pedal that feels off. Replacing the pads on both sides of the axle together is recommended for even, balanced braking. See the Buyer's Guide tab for the full list of vehicles this set fits.
