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 torque specifications important for brake components?
Why are torque specifications important for brake components?
Correct torque ensures proper clamping force, preventing bolts from loosening due to vibration and stress. Over-tightening can damage threads or distort components, leading to premature failure. Under-tightening can result in parts coming loose, which is extremely dangerous with brake components.
Q2 Where can I find the correct torque specifications for my 2009-2014 Acura TL brakes?
Where can I find the correct torque specifications for my 2009-2014 Acura TL brakes?
The torque specifications for your specific vehicle are found in the vehicle's service manual. You can also often find them on reputable automotive parts websites or forums dedicated to your vehicle model. It is not recommended to rely on general torque figures, which can be inaccurate for specific bolts.
Q3 What tools do I need to properly torque brake bolts?
What tools do I need to properly torque brake bolts?
You will need a calibrated torque wrench, sockets of the correct size for your bolts, and potentially an extension. Ensure your torque wrench is within its calibration period for accurate results.
Q4 Do I need to use threadlocker on brake bolts?
Do I need to use threadlocker on brake bolts?
Typically, only the brake caliper bracket bolts will require thread locker compound. It's essential to consult your service manual to verify the exact specifications for your vehicle and bolts. Re-use of threadlocked bolts should be avoided.
Q5 How often should I check the torque on my brake components?
How often should I check the torque on my brake components?
It's a good practice to check the torque of critical brake components after performing brake work such as pad or rotor replacement. After initial installation, it's advisable to re-check after the first 50-100 miles and then again as part of routine brake inspection.
