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 components?
Why are torque specifications important for brake components?
Correct torque is critical for brake safety and performance. Under-tightening can cause bolts to loosen, leading to component failure, while over-tightening can stretch or break bolts, damage threads, or distort brake components like rotors. This can severely impact braking effectiveness and safety.
Q2 What happens if I overtighten a brake caliper bolt?
What happens if I overtighten a brake caliper bolt?
Overtightening a caliper bolt can damage the threads in the caliper bracket or the bolt itself. This can lead to stripping the threads, requiring costly repairs. It may also distort the caliper housing, affecting piston movement and causing brake drag or uneven pad wear. In extreme cases, the bolt can shear, resulting in brake component failure.
Q3 Can I reuse brake caliper mounting bolts?
Can I reuse brake caliper mounting bolts?
It's generally recommended to replace brake caliper mounting bolts whenever they are removed, especially those that use a thread-locking compound. This is because the threads can become stretched after use and lose their clamping force and holding torque when re-used. Reusing an old bolt can affect brake performance.
Q4 What type of lubricant should I use on brake hardware?
What type of lubricant should I use on brake hardware?
Use a high-temperature, synthetic brake lubricant specifically designed for brake components. Apply it to the contact points between the brake pads and caliper, as well as the caliper slide pins (if applicable). Avoid petroleum-based lubricants, as they can degrade rubber components. Do not apply to braking surfaces themselves.
Q5 How often should I inspect my brake components?
How often should I inspect my brake components?
It's advisable to inspect your brake system at least every six months, or with every oil change, or if you experience any braking abnormalities. Check the brake pads for wear, rotors for scoring or damage, caliper for proper function and leaks, and all mounting hardware for tightness and good condition.
