Detailed Product Description

This disc brake rotor is specifically engineered for Acura and Honda vehicles such as the Accord, CL, MDX, Odyssey, Pilot, TL, and TSX. The rotor’s vented construction allows air to flow through the rotor vanes, reducing heat buildup during braking. The cross-drilled holes and slots on the rotor surface help to prevent brake fade by dissipating gases and debris generated during braking. With a nominal thickness of 28.000 mm and a discard thickness of 26.000 mm, this rotor maintains structural integrity and performance throughout its service life. The floating disc mounting and straight vane style contribute to consistent braking feel and efficient cooling.

Common Applications and Problem Solving

• Reduces brake fade during aggressive or extended braking
• Improves heat dissipation to prevent rotor warping
• Helps maintain consistent brake pad contact and performance
• Minimizes brake dust buildup on rotor surface
• Compatible with ABS systems without tone ring interference

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (26.000 mm) before installation
• Verify compatibility with vehicle make and model: Acura and Honda Accord, CL, MDX, Odyssey, Pilot, TL, TSX
• Use proper torque specifications for mounting bolts on the 5-lug pattern
• Inspect brake pads and calipers for wear or damage during rotor replacement
• Perform a bed-in procedure after installation to optimize rotor and pad performance
