Frequently Asked Questions

Find answers to common questions about torque specifications

Q1

Are these brakes compatible with all 2004-2009 Lexus RX models?

Yes, these brakes are specifically designed to be compatible with all trims of the 2004-2009 Lexus RX, including the RX 330, RX 350, and RX 400h. They meet OEM specifications for rotor size, pad material, and caliper fitment. Always verify your vehicle’s exact model year and trim before purchase to ensure compatibility.

Q2

What is the recommended maintenance schedule for these brakes?

Brake pads should be inspected every 12,000 miles or annually, while rotors should be checked for wear every 25,000 miles. Replace pads when thickness is below 3mm and rotors if they are scored, warped, or below minimum thickness specifications. Regular cleaning and lubrication of caliper slides are also recommended for optimal performance.

Q3

How do I replace the brakes on a 2004-2009 Lexus RX?

To replace the brakes, first, lift the vehicle and remove the wheels. Use a wrench to remove the caliper bolts, then slide the caliper off the rotor. Replace the brake pads and inspect the rotor. If necessary, replace the rotor. Reassemble the caliper and secure it with bolts. Finally, reinstall the wheels and lower the vehicle. Always test the brakes before driving.

Q4

What should I do if my brakes are squeaking or vibrating?

Squeaking may indicate worn brake pads or contamination on the rotor surface. Clean the rotor and replace the pads if necessary. Vibrations could be caused by warped rotors, which should be resurfaced or replaced. Also, check for loose components or uneven wear, and ensure proper lubrication of caliper slides.

Q5

How can I optimize the performance of my brakes?

Use high-quality brake pads and rotors designed for your vehicle. Avoid aggressive driving, which can cause overheating and premature wear. Regularly inspect and clean brake components to ensure proper function. Consider upgrading to performance brake pads or slotted rotors for improved stopping power and heat dissipation.
