Frequently Asked Questions

Find answers to common questions about torque specifications

Q1

What is the brake rotor size for the 2012-2015 Audi RS4?

The 2012-2015 Audi RS4 is equipped with ventilated and perforated brake rotors. The front rotors measure 365 mm in diameter and 34 mm in thickness, while the rear rotors measure 324 mm in diameter and 22 mm in thickness. These dimensions are critical for ensuring proper brake performance and compatibility.

Q2

What type of brake pads are recommended for the Audi RS4?

Audi recommends using high-performance ceramic brake pads for the RS4. These pads are designed to handle the vehicle's high-speed capabilities and provide consistent braking performance under extreme conditions. Genuine Audi brake pads (part number 8W0698151M for front and 8W0698451M for rear) are recommended for optimal performance and warranty compliance.

Q3

How often should the brake fluid be replaced on the Audi RS4?

Audi recommends replacing the brake fluid every two years or 30,000 miles, whichever comes first. The RS4 uses DOT 4 brake fluid, which must meet Audi specification VW 501.14. Regular replacement ensures proper brake system function and prevents moisture buildup, which can lead to brake failure.

Q4

What is the recommended brake service interval for the Audi RS4?

Audi recommends inspecting the brake system every 10,000 miles or annually. This includes checking brake pad thickness, rotor condition, and fluid levels. Brake pads should be replaced when they reach a minimum thickness of 3 mm, and rotors should be replaced or resurfaced if they fall below the minimum thickness specifications (front: 32 mm, rear: 20 mm).

Q5

Can I upgrade the brakes on my Audi RS4?

Yes, the Audi RS4 can be upgraded with aftermarket or Audi Sport performance brake systems. However, any modifications must comply with Audi's technical specifications to ensure safety and performance. Upgrading to larger rotors or high-performance calipers may require additional modifications, such as wheel spacers or larger wheels, to accommodate the new components.
