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 What happens if I overtighten brake bolts?
What happens if I overtighten brake bolts?
Overtightening brake bolts can lead to several issues, including damaged threads, stretched bolts (making them unsafe for re-use), and warped components such as brake rotors or calipers. In a worst-case scenario, a bolt could break during operation, leading to brake failure. Always use a torque wrench set to the specified torque value.
Q2 What happens if I undertighten brake bolts?
What happens if I undertighten brake bolts?
Undertightening brake bolts can be just as dangerous as overtightening. Loose bolts can vibrate free over time, leading to component failure. For example, a loose caliper bracket bolt could cause the caliper to shift, potentially damaging the rotor and causing complete brake failure. Always use a torque wrench to ensure bolts are properly tightened.
Q3 Do I need to use new bolts when working on my Integra's brakes?
Do I need to use new bolts when working on my Integra's brakes?
It's generally recommended to replace critical brake bolts, especially caliper bolts and banjo bolts, with new ones during brake service. These bolts can stretch or become fatigued over time, and re-using them could compromise the braking system's safety. It's often best practice to check if OEM specifies torque-to-yield bolts, in which case replacement is crucial.
Q4 What type of lubricant should I use on brake bolts?
What type of lubricant should I use on brake bolts?
For most brake bolts, a small amount of anti-seize compound or a thin coat of a high-temperature compatible brake lubricant is beneficial. This can help prevent corrosion and make future removal easier. However, some bolts, such as caliper mounting bolts, may have dry torque specifications. Always check your Integra's service manual for specific recommendations.
Q5 Where can I find the specific torque specifications for my Integra's brakes?
Where can I find the specific torque specifications for my Integra's brakes?
The most reliable source for torque specifications is the Acura Integra's factory service manual for your specific year (1994-2001). You can also often find these specifications in online databases or through reputable forums dedicated to Integra maintenance. Do not rely solely on generic charts, as variations may exist.
