Audi Audi A5 2007-2016 Brake System Bolt Torque Specifications

Using the correct torque is crucial for brake safety. Under-torquing can cause bolts to loosen over time, leading to brake failure, while over-torquing can stretch or break bolts, also resulting in failure. Proper torque ensures the components are clamped together with the correct force, preventing movement and maintaining braking performance. For example, a loose caliper bolt can cause uneven braking and potentially complete brake loss.

While a torque wrench is highly recommended for brake work, if you don't have one, you should not proceed. A proper torque wrench and accurate torque specs are a necessity for the proper and safe installation of brake system components. It's best to borrow one, rent one, or purchase one from an auto parts store. Never attempt to guess torque values, as it is dangerous. Consider taking your vehicle to a professional if you don't have the tools, as improper torquing could lead to catastrophic brake failure.

Generally, these specifications are applicable to most 2007-2016 Audi A5 models with standard brake systems. However, it's always best to verify these values in your vehicle's specific repair manual or with a qualified mechanic, as some sport or performance models might have different specifications, especially with upgraded calipers or rotor sizes. An S5 for example might require higher specs than a standard A5.

It's a good practice to check the torque on brake bolts after any brake service, such as rotor, pad or caliper replacement, after approximately 50-100 miles, just to ensure they haven't loosened up from the bedding in of the new parts. It's also recommend to check them at least annually. A good practice is when you perform seasonal tire changes, to give the brakes a once over and check for the correct torque.
