Detailed Product Description

This Centric disc brake rotor features a solid, smooth surface type that ensures even pad contact and reliable stopping power. The floating disc mounting design allows for slight movement to reduce stress and improve heat dissipation during braking. With a nominal thickness of 0.394 inches and a discard thickness of 0.315 inches, this rotor meets precise wear limits to maintain safety and performance. The fully coated finish on both the disc and hat surfaces protects against environmental elements, reducing the risk of rust and extending rotor life. The rotor is designed for vehicles with a 5-lug wheel pattern, including Chevrolet, Geo, GMC, and Suzuki models such as the Samurai, Sidekick, Tracker, and X-90.

Common Applications and Issues Addressed

• Replacement for worn or warped rotors causing brake pulsation
• Corrosion damage on original rotors affecting braking efficiency
• Uneven brake pad wear due to rotor surface imperfections
• Noise or vibration during braking from rotor surface irregularities
• Upgrading to a fully coated rotor for improved rust resistance

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (0.315 inches) before installation
• Clean mounting surfaces to prevent uneven rotor seating
• Torque lug nuts to manufacturer specifications for proper fitment
• Check compatibility with ABS systems; this rotor does not include an ABS tone ring
• Inspect brake pads and replace if worn to ensure optimal rotor performance
