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 What is the importance of proper torque specs for brake bolts?
What is the importance of proper torque specs for brake bolts?
Proper torque specs for brake bolts ensure the safety and reliability of the braking system. Over-torquing can damage the threads or strip the bolts, while under-torquing can lead to loose bolts and reduced braking performance. Always refer to the manufacturer's specifications for the correct torque values.
Q2 How often should I check and maintain my brake bolts?
How often should I check and maintain my brake bolts?
It's recommended to check and maintain your brake bolts every 12,000 to 15,000 miles or as specified in your owner's manual. Inspect the bolts for signs of wear, corrosion, or damage, and re-torque them as needed. Additionally, always clean and lubricate the threads before re-torquing.
Q3 Can I use a torque wrench with a socket extension to torque my brake bolts?
Can I use a torque wrench with a socket extension to torque my brake bolts?
Yes, but be cautious when using a torque wrench with a socket extension. The extension can add flexibility to the wrench, which may affect the accuracy of the torque reading. Always use a high-quality torque wrench and extension, and ensure the extension is securely attached to the wrench and socket.
