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 crucial for brake safety. Under-torquing can cause bolts to loosen, leading to component failure or loss of braking. Over-torquing can damage threads, cause component warping, or make future disassembly difficult or impossible. Precise torque ensures proper clamping force, preventing vibrations, premature wear, and maintaining the integrity of the braking system. It is important for uniform pressure distribution.
Q2 What happens if I overtighten a brake caliper bolt?
What happens if I overtighten a brake caliper bolt?
Overtightening a brake caliper bolt can stretch or weaken the bolt, potentially leading to thread damage in the caliper or the mounting bracket. This could result in bolt failure, improper brake function, and expensive repairs including replacing the caliper or bracket. Additionally, it can cause warping of the brake components, compromising braking performance.
Q3 Can I use a regular wrench if I don't have a torque wrench?
Can I use a regular wrench if I don't have a torque wrench?
While it is *possible* to use a regular wrench, it is *highly discouraged* for brake components. A torque wrench ensures the bolts are tightened to the correct specification, which is vital for safety and performance of the braking system. Using a regular wrench risks over or under-tightening, creating unsafe conditions and potential damage. We strongly recommend using a calibrated torque wrench for brake work.
Q4 What is a good practice for applying torque to brake bolts?
What is a good practice for applying torque to brake bolts?
Always use a calibrated torque wrench. Tighten the bolts in a star or crisscross pattern to ensure even pressure distribution. Gradually increase the torque to the final specified value in two or more steps. For example, if the final torque spec is 100 ft-lbs, first apply 50 ft-lbs to all bolts in a star pattern, then 100 ft-lbs. This prevents uneven clamping and ensures the best seal and stability. Do not lubricate the bolts unless otherwise specified.
Q5 How often should I check the torque on my brake bolts?
How often should I check the torque on my brake bolts?
It's good practice to check the torque on brake components after initial brake work and after the first 50 to 100 miles to ensure no settling or loosening has occurred. Afterwards, it is recommended to check your brake components whenever you perform any regular tire rotations or maintenance, or if you notice any unusual sounds or vibrations coming from your brakes. Regular visual inspections are also advised to check for any signs of loose bolts.
