DISC BRAKE ROTOR
DISC BRAKE ROTOR
$129.99

Bring steady, confident stops back to your Audi A4 brake rotor with the HELLA BRAKES Disc Brake Rotor 355123122, a direct-fit front replacement for the 2012-2016 Audi A4 and A4 Quattro, 2012-2014 Audi A5, 2012-2017 Audi A5 Quattro, 2011-2017 Audi Q5, 2013-2016 Audi Allroad, and more (see the Buyer's Guide tab for the full list). It measures 320 mm in outside diameter with a 30 mm nominal thickness, a 28 mm discard thickness, and an internally vented, non-directional design that routes air through the disc to help manage braking heat.

  • High-carbon gray cast iron: high carbon content helps with heat dissipation and, with soft casting materials, helps dampen noise and vibration.
  • Full zinc coating: coated disc and hat surfaces provide rust protection.
  • Ready to install: a non-oiled surface eliminates degreasing, and a fixing screw is included.
  • ECE R90 ready, mill balanced: 112 mm bolt circle, smooth surface finish, built to OEM standards.

This rotor does not include an ABS tone ring, wheel hub, wheel studs, or bearings. Sold individually; each listed application uses two front rotors, so order a pair and replace both sides together for even, balanced braking. Country of origin: China.
