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 precise torque specifications important for brake bolts?
Why are precise torque specifications important for brake bolts?
Incorrect torque on brake caliper bolts can lead to premature failure. Too little torque, and the bolts can loosen under stress, potentially leading to brake failure. Too much torque can damage the threads in the bolts or the mounting points, also leading to failure. Using the correct torque ensures proper clamping force, preventing vibrations, and maintaining the integrity of the braking system.
Q2 What happens if I don't use the correct torque wrench?
What happens if I don't use the correct torque wrench?
Using a torque wrench that is not calibrated or a non-torque wrench can lead to incorrect tightening. Using a non-torque wrench risks over-tightening, damaging the components, or under-tightening, resulting in a dangerous situation. Always use a calibrated torque wrench that is suitable for the specified application.
Q3 How often should I check and re-torque the brake caliper bolts?
How often should I check and re-torque the brake caliper bolts?
Regular inspection and re-torque of brake caliper bolts is crucial, especially after significant driving conditions like towing heavy loads, or after major repairs or maintenance affecting the braking system. It's recommended to check and re-torque at least every 25,000 miles or as per your vehicle's maintenance schedule.
Q4 What if I accidentally over-tightened a brake bolt?
What if I accidentally over-tightened a brake bolt?
If you suspect you've over-tightened a brake bolt, immediately consult a qualified mechanic. Attempting to loosen it yourself could damage the bolt or worsen the situation. The mechanic can determine the extent of the damage and safely rectify the issue.
