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 it important to use the correct torque specifications for brake components?
Why is it important to use the correct torque specifications for brake components?
Using the correct torque ensures proper clamping force, preventing bolts from loosening due to vibration or thermal expansion. Under-tightening can lead to component failure, while over-tightening can damage threads or distort parts. For example, an over-torqued caliper bolt could bind the caliper, leading to premature brake wear or failure.
Q2 Can I reuse brake caliper bolts?
Can I reuse brake caliper bolts?
While some bolts may appear reusable, it's generally recommended to replace brake caliper bolts (especially torque-to-yield bolts) each time they are removed. These bolts can stretch after being torqued once, and reusing them may not achieve the correct clamping force, potentially leading to brake failure. If reuse is absolutely necessary, clean the threads thoroughly and apply a thread locker.
Q3 What is the difference between 'lb-ft' and 'Nm' when referring to torque specifications?
What is the difference between 'lb-ft' and 'Nm' when referring to torque specifications?
Lb-ft (pound-feet) and Nm (Newton-meters) are both units of torque. Lb-ft is commonly used in the US, while Nm is the standard unit in most other countries and often in manufacturer specifications. 1 lb-ft is approximately equal to 1.356 Nm. Ensure your torque wrench is set to the correct unit before tightening any bolts. Accidentally using the wrong unit could result in significant over- or under-tightening of bolts.
Q4 How often should I check my brake components?
How often should I check my brake components?
It's recommended to inspect your brakes during each tire rotation or at least every 6 months, whichever comes first. Visual checks should include the condition of brake pads, rotors, calipers, and brake lines. Additionally, listen for any unusual noises such as squealing or grinding. Early detection can prevent major brake system issues.
