What this part is

Stocked for Mercedes-Benz and referenced by A2224212612.

Build & materials

Built to the original equipment drawing, the Brake Disc uses Metal and follows the same inspection checkpoints as the reference sample. Tolerances that affect installation are held to the drawing rather than adjusted on the bench.

• Metal construction for daily and workshop use.
• Surface treated to resist corrosion in road and workshop conditions.
• Dimensional check against the reference sample before packing.

Material and build choices answer the most common brake disc replacement and brake disc guide questions from workshop buyers.

Applications & use cases

Suitable for Mercedes-Benz. Brake Disc is stocked for these markets and model families so buyers can match demand without re-checking every listing.

Technical notes

Deep dive. SYMPTOMS: On the W222 S 63 and S 65 AMG, the 390 mm front ventilated discs convert the braking energy of a two-tonne luxury saloon with 585 to 630 hp. Wear first appears as a fine steering tremor under light braking at speed, worsened by corrosion at the centering seat; long mountain descents can leave heat spotting and a hardened, glazed band that pads cannot grip consistently. Because these are high-output AMG platforms, uneven disc thickness becomes noticeable through the precision-tuned chassis long before the wear sensor triggers.

Technical background. INSTALLATION: Confirm the vehicle is an AMG version requiring the 390 mm reference before ordering, since the W222 also used smaller front discs on non-AMG variants. Clean the hub face and the 67 mm centering seat carefully; residual corrosion here is the main cause of repeat runout complaints on this chassis. Mount with five bolts tightened in stages to the workshop manual value, and bed the new discs with progressive braking from moderate speeds, avoiding ABS events during the first bedding sessions so the pads seat evenly.

Application context. MAINTENANCE: Measure the friction band with a micrometer at several circumferential points: new thickness is 36 mm and the stated minimum is 33 mm, so about 1.5 mm per side governs replacement planning on these wheels. Check radial and axial runout with a dial gauge after any wheel or hub work, and inspect the vent ribs for heat cracking. AMG drivers should expect shorter disc life than the standard S-Class suggests, since higher sustained speeds and repeated heavy braking consume the 3 mm wear allowance quickly.

Deep dive. BUYING GUIDE: Replacement listings for this reference differ mainly in construction detail and coating: catalogs describe the 390 mm AMG rotor in coated, high-carbon finished form, and some sources list a two-piece composite construction, so buyers should match construction type to the original wheel-end rather than assume one format. Plain vented faces are the correct choice; drilled variants marketed for looks add crack risk under AMG-level braking loads. Compare the stated 36/33 mm thickness pair, the 67 mm centering, and coating quality on the hat and edges, which drives winter corrosion life.

Application context. STANDARDS: UN Regulation 90 applies to replacement discs for passenger cars in ECE markets, and at least one replacement program for the A 222 421 26 12 reference (goCORE GCH21240) explicitly lists ECE R90 approval alongside its GG20 grey cast iron material and anti-corrosion coating. Because AMG applications push discs near their thermal limits, an R90-tested replacement provides documented braking-performance equivalence rather than a dimensional match alone. Buyers should record the approval number from the casting; non-EU markets, notably the Gulf region where these cars are common, rely on cross-number matching instead.

Deep dive. BUYER PROFILE: Buyers are owners of W222 S 63 AMG, S 65 AMG and S 650 Maybach vehicles, specialists servicing C217 Coupe and A217 Cabriolet derivatives, and luxury-car parts distributors in the Gulf, where 2013-2020 S-Class AMG fleets are heavily represented. Because the reference sits in a premium tier above standard S-Class discs, resellers qualify buyers by VIN or PR code before committing stock. Workshops performing wheel-end work on these cars typically replace the discs in axle pairs with new wear sensors and pads, matching service-contract expectations.

Application context. On an S-Class W222 front axle, renewing this 390 mm vented disc goes together with pads and their wear sensor, caliper guide-pin service, and inspection of the hub bearing and axle nut. Mercedes pairs pads and discs by friction grade, so mixed brands across an axle can change pedal feel on a heavy limousine. While the wheel is off, clean the hub face and check the wear-sensor wiring routing. Plan to replace the sensor whenever the pads are renewed, since reusing an old sensor is a frequent cause of false dashboard warnings.

Application context. A 390 mm limousine disc is a heavy, precisely machined part: suppliers typically ship it in a carton with molded supports, and friction faces carry rust-preventive oil that must be degreased before installation while coating on non-friction areas can remain. Inspect the vane section and the hat for transit damage, because the vented core is less tolerant of shock than a solid disc. Store upright or flat in a dry room, never outdoors; the machined surfaces flash-rust in humid conditions, and deep rust inside the vanes shortens the usable life.

Application context. Prepare a micrometer for thickness measurement against the disc's stamped wear limit, a torque wrench covering both the caliper bracket bolts and the wheel bolts, and a runout dial indicator for the final check. The caliper on this axle is heavy; support it on a hook, never on the brake hose. Clean the hub-to-disc mating face thoroughly, as even a thin rust film here causes thickness-variation judder at highway speed. Use new securing bolts or thread lock where the design specifies, and work through the torque sequence in stages.

Application context. A long-wheelbase luxury sedan imposes year-round thermal and chemical stress on 390 mm rotors: summer highway cruising with luggage and rear-seat climate load heats the front axle on descents, while winter road salt creeps into the vent channels and pads, roughening the friction band. Brake gently for the first kilometers on frosty mornings until surfaces are dry, and avoid hard stops immediately after deep puddles, since thermal shock on a hot vented disc risks distortion. Check thickness and surface condition with each seasonal tire change.

Technical background. For distributors buying this Mercedes reference in volume, agree a documentation set per batch at order time: material certificates, hardness and balance test records, dimensional inspection sheets (diameter, thickness, height, bolt circle), and batch markings on each casting so complaints trace back. State which quality documents accompany the delivery in the contract, because requesting paperwork after arrival delays warehouse release. Sample-measure one unit per batch against the drawing before allocating stock to branches, and keep the batch file with the shipment until the last unit sells.

Deep dive. Mercedes S-Class and CL models share many front-brake geometries, and the A222 numbering generation spans several brake options: different front diameters, single-piece versus composite constructions, and superseding references across model years, so the 390 mm vented disc must be confirmed by the vehicle's option code or the casting number on the removed part. Some W222 brake systems mount the rotor on the hub with different bolt patterns; others differ in height or hat design while sharing the outer diameter. Assuming the diameter alone guarantees fitment is the most common, and costly, ordering mistake here.

Supply note. 5-bolt mounting (catalog variants list a 5/7 hole pattern) on a 112 mm bolt circle; material grey cast iron, with GG20 grade cited by one replacement program.

Application note. Fitment 2013-2020: W222 S 63 AMG and S 65 AMG, S 650 Maybach, plus C217 Coupe and A217 Cabriolet AMG derivatives with 585-630 hp engines.

Application note. goCORE replacement listing for this reference states ECE R90 approval and an anti-corrosion coating; replacement catalogs describe a high-carbon finish.

Supply note. OE numbers A 222 421 26 12 and 2224212612; Brembo catalogue reference 09.C12733 for the same application.

Supply note. Front axle disc: 390 mm outer diameter, internally vented, 36 mm new thickness, 33 mm minimum thickness, height 64.5 mm, centering diameter 67 mm.
