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 brake bolt torque specifications important?
Why are brake bolt torque specifications important?
Proper torque on brake caliper bolts, wheel studs, and other related components ensures secure fastening. Insufficient torque can lead to loosening and potential failure during critical braking maneuvers, like an emergency stop. Excessive torque, while seemingly secure, can damage the threads, leading to future problems. Following the specifications prevents premature component wear and maintains the integrity of the braking system.
Q2 What if I accidentally over-tighten a brake bolt?
What if I accidentally over-tighten a brake bolt?
Over-tightening can strip threads on the bolt or the component it's attached to. If you suspect over-tightening, the affected bolt should be removed, the threads cleaned, and a new bolt used. Contact a qualified mechanic if you're unsure how to proceed.
Q3 How do I know if the torque wrench is calibrated?
How do I know if the torque wrench is calibrated?
A calibrated torque wrench is crucial for accurate torque application. Regularly check the calibration date on your torque wrench. If it's past the calibration date, have it recalibrated by a professional. Using a non-calibrated wrench could lead to incorrect torque, negatively impacting brake performance and safety.
Q4 What if a brake bolt is rusted or damaged?
What if a brake bolt is rusted or damaged?
Do not attempt to force a rusted or damaged bolt. Replacing the damaged bolt or component is essential. Rusted or damaged bolts can lead to insufficient fastening, increasing the risk of failure during braking.
