• Description:

  The Genuine Audi Bolt N91189001 OEM is the factory-correct caliper bracket mounting bolt designed for secure installation of the brake caliper support to the steering knuckle or axle carrier. This high-strength fastener is engineered to withstand extreme braking force, heat, and vibration, ensuring precise caliper alignment and reliable stopping performance.

  Manufactured to Audi’s exact torque and tensile specifications, this bolt guarantees proper clamping force and prevents brake noise, uneven pad wear, or caliper movement. Ideal for brake service, rotor replacement, or professional rebuilds, this hardware should always be replaced rather than reused per Audi TSB and service guidelines.
