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 for brake bolts so important?
Why is using the correct torque specification for brake bolts so important?
Using the correct torque specification is crucial for brake system safety and performance. Over-tightening bolts can cause them to stretch, weaken, or break, potentially leading to component failure and loss of braking ability. Under-tightening can cause bolts to loosen, resulting in vibration, noise, and eventual component detachment. For example, a loose caliper mounting bolt could lead to complete brake failure. Always use a calibrated torque wrench to achieve the specified torque.
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 the best practice, if you absolutely must tighten bolts without one, you should strive to tighten them firmly and evenly. However, this method is highly discouraged for critical brake components. An 'educated guess' can still lead to over-tightening or under-tightening. Consider a scenario where a wheel falls off because the lug nuts were only 'hand tightened'. This is a dangerous and avoidable situation. Always invest in a torque wrench for brake work.
Q3 Do I need to replace brake bolts every time I work on the brakes?
Do I need to replace brake bolts every time I work on the brakes?
While not always required, it's generally a good idea to replace one-time use bolts, especially if they've been stretched beyond their torque spec. For instance, caliper mounting bolts are often recommended to be replaced after several uses or if they've been previously over-tightened. Always inspect bolts for signs of wear, rust, or damage. If uncertain, consult your vehicle's repair manual for specific recommendations. Using new bolts is an inexpensive insurance policy against brake failure.
Q4 What is the difference between torque specification in foot-pounds (ft-lb) and Newton-meters (Nm)?
What is the difference between torque specification in foot-pounds (ft-lb) and Newton-meters (Nm)?
Foot-pounds (ft-lb) and Newton-meters (Nm) are both units of torque, representing the rotational force applied to a bolt. They are directly convertible, but it's important to use the correct unit for your specific torque wrench. For instance, a typical Acura RL might require 80 ft-lb for the caliper bracket bolt. If your wrench is in Nm, you'd need to convert this to approximately 108 Nm using an online converter or your tool's specific conversion rate. Always double-check your units before torquing a bolt.
