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 What happens if I overtighten brake bolts?
What happens if I overtighten brake bolts?
Overtightening brake bolts can stretch or damage the threads, leading to bolt failure, potential brake component damage, and compromised braking performance. This could result in brake failure or loss of control. For example, overtightening a caliper bracket bolt can warp the bracket or damage the caliper mounting threads, requiring costly repairs.
Q2 What happens if I undertighten brake bolts?
What happens if I undertighten brake bolts?
Undertightening brake bolts can allow components to loosen over time, leading to rattling, vibration, and potential failure. In the case of the brake caliper bolts, it can cause the caliper to shift or disengage which will severely diminish braking force and also damage the rotor. This could result in loss of brake function and an unsafe driving condition. Regularly check torque on brake components, especially after maintenance.
Q3 Do I need to use new bolts every time I work on my brakes?
Do I need to use new bolts every time I work on my brakes?
While not always required, it is highly recommended to replace torque-to-yield (TTY) bolts, which are common in braking systems, each time they are removed. These bolts are designed to stretch slightly when tightened to their specific torque and are not meant to be reused. Using old TTY bolts may lead to improper torque values and compromised brake safety. Other bolts should be inspected and replaced if they show any signs of wear or damage.
Q4 Should I use a torque wrench when working on brake bolts?
Should I use a torque wrench when working on brake bolts?
Absolutely. Using a torque wrench is crucial for properly tightening brake bolts to the manufacturer's specifications. Using hand tools alone can lead to either over or under-tightening, which has significant safety implications. Using a torque wrench ensures correct clamping force and minimizes the risk of bolt or component failure. Always use an accurate, calibrated torque wrench and refer to the proper torque specifications for your specific vehicle.
Q5 Are the torque specs for front and rear brakes the same?
Are the torque specs for front and rear brakes the same?
No, torque specifications for front and rear brake components are often different due to variations in component size and materials. It is crucial to refer to the manufacturer's service manual or specifications for the 2020-Present Chrysler Voyager to ensure each bolt is tightened to the correct value.

Technical Service Bulletins
Brake Noise During Cold Operation
2021-05-15Some 2020-2021 Voyager models may exhibit brake noise during cold starts or in cold weather conditions. This noise is typically related to brake pad material and is considered normal.
Resolution: No action is required; this is a characteristic of the brake system. However, ensure proper brake pad installation and torque specifications are followed during service. Inspect pads for excessive wear.
Brake Pedal Feel Concerns
2022-03-20Some 2020-2022 Voyager models may exhibit complaints of a soft brake pedal feel or increased stopping distance. This can sometimes be related to improper brake bleeding or a potential issue with the master cylinder.
Resolution: Perform a thorough brake bleed procedure, verifying there is no leaks present in the system. Check for proper torque of all system components. Inspect the master cylinder for damage, leaks or potential fault.
Rear Brake Pad Wear Issue
2023-01-10Certain 2021-2023 Voyager models have shown a higher rate of rear brake pad wear compared to the front. This may be due to an imbalance in the brake proportioning or a component wear issue.
Resolution: Monitor rear brake pad wear during regular maintenance intervals. Ensure that proper caliper lubrication is performed at service. When replacing the brake pads, ensure proper hardware installation and torque specifications are met. Inspect caliper pins for free movement.
