Why this unit sells

Buyers searching brake rotor look for the strengths listed here: direct fit, verified reference and wholesale packing.

Materials & construction

Built to the original equipment drawing, the Brake Disc uses cast iron Iron 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.

• cast iron Iron 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.

Technical insights

Field note. SYMPTOMS: On a heavy executive platform like the A8 D4 or a loaded A6 C7 Avant, the 356 mm front discs take most of the braking effort, and wear announces itself as steering-wheel judder under light braking from motorway speed, caused by thickness variation and rust jacking at the hub face. Scoring lines from trapped debris, lip formation at the outer edge, and blue-browned heat spotting after sustained downhill use are the visual markers. A long, soft pedal after pad renewal usually points to worn discs rather than pads alone.

Technical background. INSTALLATION: Confirm the axle position and brake PR code (1LF, 1LG, 1LL or 1ZK) before ordering, because the 4H0615601-family references also cover a 330 mm rear rotor, and mixing sides is a common returns cause. Clean the hub face and centering collar, chase any corrosion from the wheel-bolt seats, and tighten the five bolts to the manual's torque in stages. Coated replacement discs need no cleaning beyond wiping the friction band; bed them with a series of moderate, well-spaced stops, avoiding prolonged dragging for the first 200 km.

Technical background. MAINTENANCE: Measure thickness at several points across the wear band with a micrometer; the new disc is 34 mm and the discard dimension is 31.5 mm, figures that replacement catalogs for this reference state consistently. Check runout with a dial gauge against the hub, since corrosion at the centering diameter, not wear alone, causes most repeat judder complaints on this platform. Replace discs in axle pairs, renew pads at the same time even when partially worn, and record the thinnest measurement per wheel in the service history.

Technical background. BUYING GUIDE: Aftermarket replacements for this reference divide mainly by surface treatment: coated rotors protect the hat, edges and bolt bores through winter salt exposure, while bare discs cost less but corrode quickly on the non-friction areas. Catalog data for the main replacement brands shows a plain vented face without drilling, high-carbon machining for stable friction, and R90 approval marks; drilled or slotted variants exist in the tuning market but change pad behaviour on a platform calibrated around plain rotors. At around 13.6 to 14 kg per disc, compare shipping terms between suppliers.

Application context. STANDARDS: Replacement discs for the A6 C7, A7 and A8 D4 fall squarely within UN Regulation 90, and the major replacement brands for this reference (including Fremax, Zimmermann, FTE and Bosch catalog listings) carry explicit R90 test marks such as E1 90R approvals. For European retail buyers the R90 marking is the practical guarantee that the disc was type-tested against the original's braking performance; keep the approval number from the casting or packaging with the vehicle's service records, since inspection stations may check it at roadworthiness tests.

Deep dive. BUYER PROFILE: The buyer base splits between independent German-marque workshops servicing A6 C7, A7 and A8 D4 vehicles out of warranty, and owners tackling a front brake job when judder appears. Parts distributors in the Middle East and China stock the reference heavily because FAW Audi A6L production shares the same front disc, and the cross-reference list (4G0615301A, 4G0615301K, 4G0615301T, 4H0615301F, 4H0615301K, 4H0615301R) lets one stock line serve several catalog lookups. Fleet operators value the consistent 34/31.5 mm thickness data for maintenance planning.

Field note. On the Audi A8 4H and related platforms, this 356 x 34 mm vented disc is changed together with the front pads and, critically, the correct pad wear sensor, because the sensor part number varies with the car's brake option code (for example 4H0615121E, J, P or Q depending on options such as 1LL, 1LJ, 1LP or 1LN). Inspect the caliper guide pins and boots, replace the hub-to-disc securing hardware if corroded, and clean the wheel hub face. Matching pads to the same friction grade as the disc specification prevents judder on this heavy platform.

Field note. Large vented discs like this one are typically packed in a carton with foam spacers and a rust-preventive coating on the friction faces and hat. The coating must be cleaned from the friction band with brake cleaner before mounting, but can stay on the hub-contact area. The 34 mm section wears to a 31 mm minimum, so a transit knock on the edge matters: check the rim and the hat for dents, keep discs flat and dry in storage, and avoid stacking other parts on the box during warehouse moves.

Application context. Servicing this disc calls for a micrometer to measure against the 34 mm new and 31 mm minimum values, a calibrated torque wrench for the caliper carrier bolts and wheel bolts, and a dial indicator to verify runout after mounting. The wheel needs only normal lifting, but the caliper must be hung on a wire hook rather than the hose. Have the correct hex or star wheel-bolt socket ready, clean the hub mating face with a wire brush, and apply a thin anti-seize layer on the hub center only.

Field note. A flagship sedan running 356 mm rotors sees distinct seasonal stress: summer highway pulls with a full load heat the 34 mm section hard, so check for blueing or heat crazing during tire rotations. Winter de-icing salt corrodes the friction band between pad changes and can lift the coating off the hat, so a pre-winter measurement of thickness and a visual rust check are sensible. Repeated cold-morning stops before the brakes warm up, plus slush packed behind the wheel, accelerate uneven wear – the usual root of seasonal pedal-pulsation complaints on large Audis.

Field note. For wholesale quantities of this Audi reference, spell out the batch documentation in the purchase order: material certificates for the cast iron, hardness readings, balance or runout test records, and dimension sheets covering diameter, thickness, height and center bore. Each unit should carry a cast-in or stamped traceability mark linking it to its batch. Because the same geometry is sold under several cross-references (including 4H0615601D, K and Q and related VAG numbers), require the packing list to state which casting the shipment actually contains. Agree these points before production or dispatch, not after arrival.

Application context. This reference is a documented fitment trap. In Audi's own catalog for the A8 4H, 4H0615601H appears for specific brake option codes and production dates, with 4H0615601K superseding it after a stated date – so the same 356 x 34 mm disc family splits by chassis number. Aftermarket listings also assign the geometry to other models and even to rear positions on some vehicles, and Porsche Macan references (95B615601A and similar) cross to related numbers. Always verify against the vehicle's brake PR code or the removed part's stamping instead of trusting the diameter.

Application note. Mounting geometry: 5 stud holes on a 112 mm bolt circle, centering diameter 68 mm, unit weight approx. 13.6-14 kg.

Supply note. Catalogued fitment runs 2009-2018 by platform (A8 D4 from 11/2009; A6 C7 and A7 Sportback 2010-2018), governed by brake PR codes 1LF, 1LG, 1LL and 1ZK; the source listing markets 2007-2015 model years.

Supply note. Fitment caution: 4H0615601-family numbers are also catalogued for a 330 mm rear-axle rotor (22 mm new / 20 mm minimum), so axle side and PR code must be confirmed before ordering.

Supply note. OE cross references 4G0615301A, 4G0615301K, 4G0615301T and 4H0615301F/K/R, covering the front axle of Audi A6 C7, A7 Sportback, A8 D4, A6 Allroad and FAW A6L platforms.

Workshop note. Front disc dimensions: 356 mm outer diameter, internally vented, 34 mm new thickness, 31.5 mm minimum thickness, height approx. 52.1 mm.
