Common Mistakes to Avoid
Common Mistakes to Avoid
Over-tightening
Exceeding the specified torque value can stretch or break fasteners, damage threads, or crack components.
Always use a calibrated torque wrench and follow specifications exactly.
Incorrect Torque Sequence
Tightening bolts in the wrong order can cause uneven pressure distribution and potential leaks or damage.
Follow the manufacturer's specified torque sequence pattern.
Dirty Threads
Dirt, rust, or old thread locker can affect torque readings and proper fastener tension.
Clean and inspect all threads before assembly. Use new thread locker if specified.
Reusing TTY Bolts
Torque-to-yield bolts are designed to stretch and must not be reused.
Always replace TTY bolts with new ones. They are single-use only.
Dry vs. Lubricated
Not accounting for whether torque specs are for dry or lubricated fasteners can lead to incorrect tension.
Check if specs are for dry or lubricated threads. Use specified lubricant when required.

Frequently Asked Questions
Find answers to common questions about torque specifications
Q1 Why are correct torque specifications important for brake components?
Why are correct torque specifications important for brake components?
Correct torque specifications are critical for brake safety and performance. Over-tightening can damage threads, distort components (like rotors), and lead to failure. Under-tightening can cause components to loosen, resulting in brake failure. Consistent and correct torque ensures proper clamping force for optimal braking performance and prevents premature wear.
Q2 What happens if I over-torque a brake caliper bolt?
What happens if I over-torque a brake caliper bolt?
Over-torquing a brake caliper bolt can stretch or break the bolt, damage the caliper threads, or even distort the caliper housing. This can result in improper clamping of the caliper to the rotor, uneven brake pad wear, and potential brake failure. If you suspect you've over-torqued a bolt, it should be replaced immediately.
Q3 Can I reuse brake caliper bolts?
Can I reuse brake caliper bolts?
It's generally not recommended to reuse brake caliper bolts, especially the stretch bolts commonly used. These bolts are designed to yield (stretch) slightly when torqued, and reusing them can compromise their integrity, resulting in potential loosening or failure. New bolts should always be used with the specified torque value.
Q4 What type of torque wrench should I use for brake work?
What type of torque wrench should I use for brake work?
A calibrated click-type torque wrench is recommended for brake work. Digital torque wrenches can be used but must be regularly calibrated. Always choose a torque wrench with a range that covers the specific torque values for the bolts you are tightening. Avoid using beam-type torque wrenches as they are less precise.
Q5 How often should I check the torque of my brake components?
How often should I check the torque of my brake components?
It's a good practice to check the torque of brake components after any brake service, such as brake pad or rotor replacement. It's also recommended to check the torque periodically, especially after the first 50-100 miles after a brake service. Regular visual inspections for any signs of looseness or damage are important as well. Consider checking every 12 months as part of a general maintenance schedule.
Q6 Where can I find the specific torque specifications for my 2006-2011 Audi S6 brakes?
Where can I find the specific torque specifications for my 2006-2011 Audi S6 brakes?
The specific torque specifications for your 2006-2011 Audi S6 brakes can be found in the vehicle's service manual or a reputable repair database specific to your vehicle. It is recommended to cross-reference several sources to confirm the accuracy of the torque values.

Technical Service Bulletins
Brake Vibration at High Speeds
2008-05-15Some 2006-2008 Audi S6 models may experience vibration during braking at higher speeds. This is often due to excessive runout of the brake rotors or improper torque application on brake components.
Resolution: Replace warped rotors and ensure all brake components are torqued to the specified values. Double check caliper guide pins are free moving.
Rear Brake Caliper Seizing
2010-11-20Rear brake calipers on 2008-2011 Audi S6 models may seize due to corrosion or lack of lubrication. This can result in uneven brake pad wear and reduced braking performance.
Resolution: Disassemble, clean, and lubricate the caliper guide pins and piston. Replace any worn components and torque to specified values.
