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 important for brake components?
Why is using the correct torque specification important for brake components?
Using the correct torque specification for brake bolts is crucial for several reasons. Under-tightening can cause bolts to loosen during operation, potentially leading to brake failure or component damage. Over-tightening can stretch or break bolts, damage threads, or warp brake components like rotors and calipers, which also compromises braking performance. Proper torque ensures consistent and reliable braking force and safety.
Q2 What happens if I don't have a torque wrench?
What happens if I don't have a torque wrench?
While a torque wrench is the ideal tool, if you lack one, it's crucial to understand the risk. Attempting to estimate torque is highly inaccurate and can lead to dangerous situations. If you don't have a torque wrench, it's best to have a professional mechanic perform the brake work. If that is not an option, you will need to acquire one.
Q3 Should I use thread locker on brake bolts?
Should I use thread locker on brake bolts?
Whether to use thread locker depends on the specific brake bolt and manufacturer recommendations. Generally, for bolts that are intended to be removed for routine maintenance like caliper guide pins, thread locker is typically not needed. For bolts such as caliper bracket bolts, manufacturers sometimes recommend using a thread locker compound. Always consult the Acura RLX service manual for specific guidance on your year and model. Applying thread locker when not needed may actually lead to damage when you attempt to remove a bolt.
Q4 Do torque specifications change if I replace a bolt with a new one?
Do torque specifications change if I replace a bolt with a new one?
Generally, torque specifications remain the same regardless of whether the bolt is old or new if they are the exact same spec. However, be sure to only use OE or OE equivalent bolts to ensure proper fitment. If you're installing a new bolt, you should adhere to the original torque value. It is also generally recommended to lubricate the threads of new bolts that have a dry torque specification.
Q5 What is the difference between 'ft-lb' and 'Nm' torque values?
What is the difference between 'ft-lb' and 'Nm' torque values?
Foot-pounds (ft-lb) and Newton-meters (Nm) are both units of torque, but they use different measurement systems. Foot-pounds are an imperial unit while Newton-meters are metric. It's important to ensure your torque wrench is set to the correct unit, matching the specifications provided in your service manual, and always follow the recommended unit value.
