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 bolts?
Why is using the correct torque specification important for brake bolts?
Using the correct torque is crucial for safety and performance. Over-tightening can stretch or break bolts, damage threads, or warp brake components leading to brake failure. Under-tightening can cause bolts to loosen, resulting in noise, premature wear, and potential brake system separation. For example, an over-tightened caliper mounting bolt might crack the caliper bracket or strip the threads, while a loose one could allow the caliper to shift, causing uneven pad wear and reduced braking efficiency.
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 highly recommended, if you do not have access to one, you should tighten bolts snug then give them about a quarter turn more. However, this is not accurate and only recommended to get the car to where you can get access to a torque wrench. It is unsafe to operate a vehicle with components tightened this way. This should never be considered proper maintenance.
Q3 Should I use anti-seize on brake bolts?
Should I use anti-seize on brake bolts?
Generally, no, you should not apply anti-seize to brake bolts that are directly involved with clamping or mounting of components such as the caliper mounting bolts, caliper bracket bolts, etc. Anti-seize can alter the friction coefficient, potentially leading to over-tightening and inaccurate torque values, which can cause brake failure. Some manufacturers will suggest to put antiseize in other places on other models like the rear drum hardware. Please always check your models repair manual.
Q4 Do brake rotor retaining screws have a specific torque?
Do brake rotor retaining screws have a specific torque?
Yes they do, although their function is not holding clamping pressure like caliper bolts. These typically have a very low torque spec, somewhere around 5-10 ft lbs. They are only there to hold the rotor on during assembly.
Q5 Are there any bolts I should always replace when doing a brake job on a 1991-1995 Dodge Caravan?
Are there any bolts I should always replace when doing a brake job on a 1991-1995 Dodge Caravan?
While not all bolts need to be replaced every time, it's a good practice to replace caliper mounting bolts and any bolts that show signs of corrosion, damage, or stretching. These components are critical for braking safety and it is better to be safe than sorry. Check service manual for bolt torquing requirements if you have any doubts.
