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 components?
Why is using the correct torque specification important for brake components?
Correct torque ensures proper clamping force, preventing components from loosening due to vibration and thermal expansion. Insufficient torque can lead to bolts backing out, causing brake failure, while excessive torque can damage threads or warp components, affecting braking performance. For example, over-tightening a caliper bolt can warp the caliper bracket, leading to uneven pad wear.
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 ideal, you can try to achieve approximate tightness by feel if necessary but this is not recommended. A good rule of thumb is to tighten the bolt until snug, then give it an additional partial turn using a box-end wrench. This method relies on experience and is not precise, and should only be used as a last resort. We highly recommend getting and using a torque wrench. Inaccurate torque can lead to dangerous situations with your vehicle.
Q3 Should I use anti-seize on brake bolts?
Should I use anti-seize on brake bolts?
It's generally recommended to use anti-seize on brake caliper bolts, especially on vehicles driven in areas with high exposure to road salt. Anti-seize helps prevent corrosion and makes future removal easier. However, be careful not to apply it to the threads of bolts that go into aluminum components. Make sure to adjust torque specification appropriately if you use anti-seize. Read your torque wrench manual on how to appropriately adjust for lubricating compounds.
Q4 How often should I inspect and re-torque my brake components?
How often should I inspect and re-torque my brake components?
It's good practice to check your brake components during each tire rotation, which should be done every 5,000-7,000 miles. This inspection should include a visual check of the brake components and a check to ensure bolts are at the correct torque spec. Retorquing is especially important after any brake service or replacement. Road conditions and driving style can affect torque of your brake components over time.

Technical Service Bulletins
Brake Pedal Pulsation During Light Braking
2002-05-15Some 1999-2003 Acura TL models may exhibit a brake pedal pulsation under light braking. This is often due to uneven rotor wear or lateral runout.
Resolution: Check rotors for lateral runout and either resurface or replace as necessary. Also, confirm proper torque of caliper mounting bolts.
Rear Brake Caliper Sticking Issues
2001-11-20Certain 2000-2003 Acura TL models may have rear brake calipers that stick, causing premature pad wear and reduced braking performance.
Resolution: Inspect the rear caliper slide pins and lubricate or replace as required. Ensure correct installation and torque of all components. Clean the brake pads and rotor contact surfaces to remove rust.
