• Brake pulsation caused by rotor wear or distortion
• Reduced braking consistency on front left service replacement

Installation Notes and Tips

Verify rotor dimensions, bolt pattern, and center bore before installation. This rotor is listed for the front left position only, so match the vehicle side and axle location exactly. Inspect pads, caliper condition, and hub surface during brake service to help ensure proper rotor seating and even braking performance. Confirm fitment for your specific Acura MDX or Acura TLX by year and position before ordering.

Quality Assurance
