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 is using the correct torque specification important for brake components?
Why is using the correct torque specification important for brake components?
Using the correct torque is crucial for brake safety and performance. Under-tightening can cause components to loosen, leading to vibrations, noise, or even complete failure. Over-tightening can damage threads, warp rotors, or cause bolts to break, also resulting in component failure. Always use a calibrated torque wrench.
Q2 Can I reuse brake rotor bolts?
Can I reuse brake rotor bolts?
It's generally recommended to replace brake rotor bolts, especially those with a self-locking feature, upon removal. These bolts are often designed for single use. While reusing them *might* work, their clamping force might be compromised, affecting braking safety. New bolts ensure proper clamping and safety.
Q3 What if I don't have a torque wrench?
What if I don't have a torque wrench?
While it's possible to 'feel' the tightness, relying solely on this is risky and not recommended for brake components. Torque specifications are very precise. Not using a torque wrench can lead to a dangerous situation if components are not tightened properly. Renting or borrowing one is advisable if you don't have one.
Q4 How often should I check brake component torque?
How often should I check brake component torque?
Generally, it's good practice to check brake component torque after initial installation, after the first 50-100 miles, and during routine maintenance, like tire rotations. This ensures all bolts remain properly torqued. If you hear any unusual noises, then checking the bolts again might be necessary.
