Frequently Asked Questions

Find answers to common questions about torque specifications

Q1

What are the brake specifications for the 2014-Present Infiniti QX80?

The 2014-Present Infiniti QX80 is equipped with front and rear disc brakes. The front brakes typically feature 13.8-inch ventilated discs with dual-piston calipers, while the rear brakes use 13.8-inch solid discs with single-piston calipers. These brakes are compatible with OEM and aftermarket parts designed for the QX80. Always verify part numbers and compatibility with your vehicle's VIN to ensure proper fitment and performance.

Q2

What is the recommended maintenance schedule for the QX80 brakes?

For optimal performance, inspect the brake system every 12,000 miles or as recommended in the owner's manual. Replace brake pads every 30,000-70,000 miles, depending on driving conditions. Rotors should be checked for wear and replaced if below the minimum thickness. Brake fluid should be flushed every 30,000 miles or every two years. Regular inspections ensure safety and prevent costly repairs.

Q3

How do I replace the brake pads on a 2014-Present Infiniti QX80?

To replace brake pads, lift the vehicle and remove the wheels. Unbolt the caliper and suspend it to avoid damaging the brake line. Remove the old pads and compress the caliper piston using a C-clamp. Install the new pads and reassemble the caliper. Torque bolts to manufacturer specifications and reinstall the wheels. Test brakes before driving to ensure proper installation and functionality.

Q4

What should I do if my QX80 brakes are making noise or vibrating?

Noise or vibration may indicate worn pads, warped rotors, or debris in the brake system. Inspect pads and rotors for wear and replace if necessary. Clean the brake components to remove debris. If the issue persists, check for caliper alignment or suspension problems. Regular maintenance and timely replacements can prevent these issues.

Q5

How can I optimize the braking performance of my Infiniti QX80?

To optimize braking performance, use high-quality brake pads and rotors designed for the QX80. Upgrade to performance brake fluid for improved heat resistance. Ensure proper bedding of new pads and rotors by following the manufacturer's instructions. Regularly inspect and maintain the brake system to ensure consistent performance and safety.
