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 is using the correct torque specification so important when working on brakes?
Why is using the correct torque specification so important when working on brakes?
Using the correct torque specification is crucial for the safe and effective operation of your vehicle's braking system. Under-tightening bolts can lead to parts loosening, causing instability, premature wear, and potential failure, such as a caliper coming loose during braking. Conversely, over-tightening bolts can damage the threads or even snap the bolt, which can also lead to component failure and compromised braking performance. Imagine a caliper bolt failing due to being over-tightened - the caliper might shift, resulting in uneven braking and potential loss of control. Correct torque ensures proper clamping force, preventing these issues.
Q2 Should I use new bolts when replacing brake components?
Should I use new bolts when replacing brake components?
Yes, it is highly recommended to use new bolts when replacing brake components, especially those that are torque-to-yield (TTY) bolts which are designed to stretch when torqued. These bolts cannot be reliably reused as they have already been stretched, and their structural integrity is compromised. Reusing them can lead to insufficient clamping force, bolt failure, and potentially dangerous situations. Even non-TTY bolts may be prone to fatigue and corrosion, making replacement a best practice. For instance, always use new caliper bolts and mounting bracket bolts.
Q3 How do I know if I am torquing a bolt correctly?
How do I know if I am torquing a bolt correctly?
The most accurate way to torque a bolt is by using a calibrated torque wrench. A torque wrench will allow you to precisely apply the required amount of force as specified in the service manual. Using a non-calibrated or 'feel' method can lead to improper torquing with potentially dangerous results. Follow the manufacturer's specifications, and, if using an angle-tightening method, make sure you have the correct angle gauge. For example, you must set your torque wrench to the specified Nm/ft-lb for a caliper guide pin bolt and then tighten the bolt until the wrench clicks or the correct torque is achieved.
Q4 What should I do if I suspect a brake bolt has been overtightened?
What should I do if I suspect a brake bolt has been overtightened?
If you suspect that a brake bolt has been overtightened, the best course of action is to replace it immediately, along with any surrounding components that may have been affected. Over-tightening can stretch the bolt, damage the threads in the housing, and induce stress fractures in the material, even if no damage is immediately apparent. Continuing to use these components can result in a dangerous situation. For example, if you have over-tightened a brake rotor retaining screw, the most prudent approach would be to replace both the screw and carefully inspect the surrounding rotor for any signs of stress cracks.
