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 when working on brakes?
Why are torque specifications important when working on brakes?
Correct torque is crucial for brake safety and performance. Under-tightening can cause bolts to loosen, leading to component failure and loss of braking. Over-tightening can damage threads or distort components, potentially causing premature wear or failure. Proper torque ensures even clamping force for reliable braking.
Q2 What happens if I don't use a torque wrench?
What happens if I don't use a torque wrench?
While it might seem quicker, not using a torque wrench is risky. You're relying on guesswork, which can easily lead to under or over-tightening. For example, tightening caliper bolts 'by feel' could result in a warped rotor or a caliper coming loose. Always use a calibrated torque wrench to ensure accurate tightening.
Q3 How often should I check the torque on my brake components?
How often should I check the torque on my brake components?
It's recommended to check brake component torque periodically, especially after a new brake job or a suspension repair. A good practice is to check after the first 50-100 miles, and then at regular service intervals like every tire rotation or oil change. This helps identify any loosening issues early.
Q4 Do torque specifications change if I have upgraded brakes?
Do torque specifications change if I have upgraded brakes?
Yes, torque specifications can change if you install aftermarket or performance brake components. Always refer to the manufacturer's specifications for your specific components. Using the factory torque specs for upgraded brakes can be dangerous as the materials or bolt sizes may differ.
