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 proper torque specifications important for brake bolts?
Why are proper torque specifications important for brake bolts?
Proper torque is crucial for brake safety. Under-torquing can cause bolts to loosen, leading to component failure, such as caliper detachment or rotor warping. Over-torquing can stretch or break bolts, damage threads, and compromise the clamping force, ultimately affecting braking performance and safety.
Q2 What happens if I don't have a torque wrench?
What happens if I don't have a torque wrench?
While using a torque wrench is highly recommended, you should avoid making guesses or using excessive force. If a torque wrench is unavailable, consider borrowing one or consult a professional. Improperly torqued brake components can lead to severe safety issues. An example scenario would be attempting to tighten a caliper bracket without a torque wrench, which can lead to it being loose and breaking free during heavy braking, resulting in loss of control.
Q3 Do I need to replace brake bolts every time I do a brake job?
Do I need to replace brake bolts every time I do a brake job?
While not always necessary, it's a good practice to replace bolts that show signs of wear, damage, or corrosion. Some bolts, especially those that are designed for single-use, should always be replaced. Specifically, check bolts for stretched threads or corrosion, which are common after repeated exposure to heat and road debris. For instance, when replacing the brake rotors, you should at least inspect all the related hardware and use new bolts if the current ones seem questionable.
Q4 How often should I check the torque on my brake components?
How often should I check the torque on my brake components?
It's advisable to check brake component torque after the initial installation or after any brake service, usually after 50-100 miles of driving. If everything is within spec, subsequent checks should be done during routine maintenance, perhaps every six months or during every tire rotation, particularly after very hard driving. For instance, after your first 50 miles of driving after a new rotor installation, re-check the caliper bracket and caliper mounting bolts. A common sign that they are loose is when you hear or feel a clunk coming from the wheel during a brake application.
