BRAKE DISC

Give your front brakes a fresh, true friction surface with the HELLA Brakes Disc Brake Rotor 355129371 — a direct-fit front rotor for the 2016-2018 Audi A6, 2012-2018 Audi A6 Quattro, 2012-2018 Audi A7 Quattro, and 2013-2014 Audi A8 Quattro (all engines). Cast from high-carbon gray cast iron to meet OEM standards, this internally vented rotor has a 356 mm (14.02 in) outside diameter, a 34.0 mm nominal thickness, and a 5-hole, 112 mm bolt circle.

• Vented, high-carbon cast iron: the internally vented design and high carbon content help dissipate heat during braking.
• Full zinc coating: a full zinc coating on the disc and hat helps resist rust and corrosion.
• Quieter operation: high carbon content and 'soft' casting materials are designed to dampen noise and vibration.
• Ready to install: ships with fixing screws and a non-oiled surface, so no degreasing is required before mounting.

It's a smooth, non-directional rotor with mill balancing and a standard-replacement grade. Machine or replace it once it reaches the 31.5 mm discard thickness. It does not include an ABS tone ring, wheel hub, wheel studs, or bearings — transfer or replace those as directed by the service procedure. This rotor is sold individually. Each application uses two, so order 2 for the complete front axle; replacing both sides together as a matched pair helps keep braking even and balanced. Manufacturer part number 355129371. Country of origin: China.
