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 is crucial for maintaining the structural integrity of the braking system. Insufficient torque can lead to loosening, potentially causing brake failure during critical maneuvers like braking hard or during cornering. Excessive torque can damage threads and components, leading to premature wear and tear.
Q2 What happens if I don't use the correct torque specifications?
What happens if I don't use the correct torque specifications?
Incorrect torque can lead to a variety of issues, including brake pedal pulsation, reduced braking effectiveness, and even complete brake failure, potentially resulting in an accident. For example, if wheel studs are under-torqued, they can work loose and lead to a wheel falling off while driving, creating a severe hazard. Conversely, over-torquing can damage the wheel studs or the brake caliper mounting points, impacting safety and causing premature failure.
Q3 How often should I check the torque on brake components?
How often should I check the torque on brake components?
Inspect and re-torque brake components after any significant repairs or maintenance involving the braking system, such as brake pad replacement, caliper repair, or wheel changes. It's also wise to check torque on wheel studs and caliper bolts after any major road events, especially if you notice unusual noises or vibrations in the braking system.
Q4 What tools are needed for this task?
What tools are needed for this task?
You'll need a torque wrench capable of measuring the specified torque values for your 2000-2006 GMC Yukon. A suitable socket set, lug wrench (for wheel studs), and possibly a breaker bar for particularly stubborn nuts are also recommended for effective and safe work.
