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 for brake bolts?
Why are torque specifications important for brake bolts?
Incorrect torque on brake caliper bolts can lead to premature failure. Too little torque allows bolts to loosen, potentially leading to brake failure during operation. Too much torque can damage the threads of the bolts or the caliper mounting points, also causing failure. Proper torque ensures consistent clamping force, maintaining the structural integrity of the braking system and preventing dangerous situations like wheel wobble or brake dragging.
Q2 What happens if I don't use the correct torque wrench?
What happens if I don't use the correct torque wrench?
Using an inaccurate torque wrench (or no torque wrench at all) can result in the bolts being either under-torqued or over-torqued. Under-torquing can lead to the bolts loosening and the caliper coming off the rotor, potentially causing a total brake failure. Over-torquing can damage the mounting points and the bolts themselves, leading to catastrophic failure.
Q3 What if a bolt is stripped? How do I replace it?
What if a bolt is stripped? How do I replace it?
If a bolt is stripped, it is crucial to replace the entire bolt and nut assembly. Attempting to re-use the stripped bolt is risky and can lead to further damage. Consult your Hyundai AZERA repair manual for proper replacement procedures. Improper installation can lead to the bolt loosening and causing dangerous situations.
Q4 How often should I check the torque on the brake caliper bolts?
How often should I check the torque on the brake caliper bolts?
It's recommended to inspect and re-torque brake caliper bolts during scheduled maintenance, especially after any work involving the braking system including brake pad replacement or rotor changes. In addition, if the vehicle experiences unusual braking noises or vibrations, a professional inspection and re-torque of the caliper bolts should be performed immediately.
