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 caliper bolts?
What happens if I overtighten brake caliper bolts?
Overtightening can stretch or break the bolt, damage the threads in the caliper or knuckle, or even warp the caliper itself. This can lead to component failure, brake malfunction, and potential loss of control. For example, an overtightened caliper bolt might crack the caliper mounting point, leading to brake pad misalignment and premature wear.
Q2 What happens if I undertighten brake caliper bolts?
What happens if I undertighten brake caliper bolts?
Undertightening caliper bolts can allow the caliper to shift, leading to uneven brake pad wear, noise, vibrations, and a spongy brake pedal feel. In a worst-case scenario, the caliper could detach entirely, resulting in complete brake failure. For instance, a loose caliper could cause brake pads to drag and overheat, causing rapid pad wear and decreased braking power.
Q3 Should I use threadlocker on brake bolts?
Should I use threadlocker on brake bolts?
Generally, it is recommended to use a medium-strength (e.g. blue) threadlocker on brake caliper bolts. This helps prevent loosening due to vibrations and temperature cycling. However, always refer to your service manual for specific recommendations, as some applications may use different locking mechanisms or prefer no threadlocker. Using the wrong type of threadlocker could make future disassembly more difficult.
Q4 How often should I check my brake bolts?
How often should I check my brake bolts?
It's a good practice to check brake bolts during regular maintenance, such as tire rotations or brake pad replacements. A good interval would be every 6 months or 6000 miles. However, if you notice any unusual noises or vibrations from the brake area, check them immediately. Driving on rough roads, racing, or heavy braking may warrant more frequent checks.
Q5 Do torque specifications vary between front and rear brakes on an RSX?
Do torque specifications vary between front and rear brakes on an RSX?
Yes, torque specifications often differ between the front and rear brake components due to different caliper and rotor sizes. Always consult the specific service manual or manufacturer specifications for your 2002-2006 Acura RSX. Do not assume the same torque applies across all brake components.
