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 when working on brakes?
Why is using the correct torque specification important when working on brakes?
Using the correct torque specification is critical for brake safety. Over-tightening can damage threads, warp rotors, or compromise the integrity of the components, leading to brake failure. Under-tightening can cause components to loosen, leading to brake noise, reduced performance, or complete failure. Always use a calibrated torque wrench and refer to the manufacturer's specifications.
Q2 What happens if I don't have a torque wrench?
What happens if I don't have a torque wrench?
While it's strongly recommended to use a torque wrench for precise tightening, you can try a 'hand tight plus a little more' method. However, this is risky. For example, if you just 'guess' the torque on the caliper bracket bolts and they come loose, you risk severe damage, even loss of control. Always use a torque wrench when dealing with brakes for accurate and safe installation. If you do not have one, it is recommended to take your vehicle to a professional.
Q3 What are the torque specs for the brake caliper bracket bolts on my 2013-2018 Acura RDX?
What are the torque specs for the brake caliper bracket bolts on my 2013-2018 Acura RDX?
The torque specification for the front brake caliper bracket bolts on a 2013-2018 Acura RDX is typically 79 lb-ft (107 Nm). The rear caliper bracket bolts are usually torqued to 58 lb-ft (78 Nm). Always consult your vehicle's service manual for the most accurate information as specifications can vary. Do NOT rely solely on this provided information without confirmation in a workshop manual.
Q4 What are the torque specs for the brake caliper guide pin bolts on my 2013-2018 Acura RDX?
What are the torque specs for the brake caliper guide pin bolts on my 2013-2018 Acura RDX?
The torque specification for the front brake caliper guide pin bolts on a 2013-2018 Acura RDX is typically 20 lb-ft (27 Nm). The rear caliper guide pin bolts are usually torqued to 17 lb-ft (23 Nm). Always consult your vehicle's service manual for the most accurate information as specifications can vary. Do NOT rely solely on this provided information without confirmation in a workshop manual.
Q5 Should I use new bolts when reinstalling the brake components?
Should I use new bolts when reinstalling the brake components?
While not always required, it is highly recommended to replace brake caliper bolts, especially the bracket bolts, any time they are removed, as they can stretch with use. This prevents potential issues with proper torque being achieved. Additionally, new bolts are a good idea when they show signs of damage or corrosion. Always follow Acura's recommendations for bolt replacement.
Q6 How often should I check the torque of my brake components?
How often should I check the torque of my brake components?
It is recommended to check the torque of your brake components any time you remove them. For example, after a brake pad replacement or rotor replacement, you should check the torque after the first 100 miles and then again at a regular service interval. Pay attention to your brakes and if you hear any unusual noises, check the components right away.
