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 it crucial to use the correct torque specifications for brake bolts?
Why is it crucial to use the correct torque specifications for brake bolts?
Using the correct torque specifications is vital for brake safety. Over-tightening can stretch or break bolts, damage components like calipers, and potentially cause brake failure. Under-tightening can lead to bolts loosening over time, resulting in brake noise, vibration, or even separation of components, all of which can compromise braking performance and increase the risk of an accident. Proper torque ensures clamping force is adequate and that parts are securely joined and aligned.
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 most accurate way to tighten bolts, if you don't have one, a temporary alternative would be to use a properly sized wrench and apply firm pressure - but not overly tight - based on your experience. However, using a torque wrench is strongly recommended as a loose bolt is as dangerous as an overtightened one. It’s best to borrow or invest in one for crucial work like brake service. In the long run, it is much safer and economical. Many auto part retailers have torque wrenches that can be rented if you only require it on occasion.
Q3 Should I use new brake bolts every time I service my brakes?
Should I use new brake bolts every time I service my brakes?
It is generally recommended to replace brake bolts, especially caliper bracket bolts and caliper mounting bolts, each time they are removed. This is because these bolts can stretch and weaken after being torqued multiple times. Reusing old bolts might result in improper clamping force and potentially lead to brake failure. If reusing bolts, inspect for any signs of stretching, rust or thread damage - and replace if in doubt. Self-locking bolts must always be replaced.
Q4 What should I do if I suspect a brake bolt is damaged?
What should I do if I suspect a brake bolt is damaged?
If you suspect damage to a brake bolt, such as a stripped thread, or if the bolt is stretched or shows any sign of corrosion, you must replace it immediately. Do not attempt to reuse a compromised bolt. Ignoring this can result in brake failure leading to an accident. For example, a stripped thread may not hold the desired torque, a bent bolt may not align correctly or a rusted bolt may break under pressure.
Q5 Are torque specs the same for all brake components?
Are torque specs the same for all brake components?
No, torque specifications vary significantly for different brake components. For example, caliper bracket bolts require higher torque than the caliper slide pins. Always refer to the specific service manual or manufacturer guidelines for your 2013-2019 Buick Encore. Using the wrong spec for a component can damage it. An example of this is over-tightening a slide pin, which may lead to binding, preventing the caliper from applying even pressure.
