OE 1684201120 — Brake Pads for Mercedes-Benz

Start from the code cast or printed on the part you are removing — that is the authoritative source. If it is illegible, use the Applications table on the closest brake system reference and narrow by build year. Send photos and we will cross-check the number for you.

Yes, if the alternate shares the same engineering envelope. Shortlist candidates from the Related OE References table, then check bolt pattern, electrical pinout and material grade. A difference in any of those three means it is a different part, not a substitute.

Incoming batches pass a dimensional check, a material look-up against the brake system specification, and a visual inspection for finish defects. Critical dimensions are measured per carton and the photographs are archived against the order number.

Noise normally traces to worn internal surfaces, a loose mount, a dry bearing or contact with a neighbouring part. Isolate it by reproducing the sound at a fixed speed, then compare against the reference photo for 1684201120 to confirm the right replacement.

Four variables explain most of the spread: material grade, whether the goods are new production or clearance stock, packing format, and whether the quote is ex-works or landed. Ask for the material certificate alongside the price — that is what makes a comparison like-for-like.

Three checks: the code printed on your old part must read 1684201120; the number must fall inside the build-year range in the Applications table; and the connector, thread or bolt pattern must match the reference photo. Codes cast into the housing are the most reliable source.
