Detailed Product Description

This Centric disc brake rotor features a solid design with a smooth surface type, optimized for consistent braking without the complexity of vented rotors. The rotor’s nominal thickness is 0.394 inches (10.000 mm), with a discard thickness of 0.331 inches (8.400 mm), indicating the minimum thickness before replacement is necessary. The overall height measures 1.976 inches (50.200 mm), and the outside diameter is 11.012 inches (279.700 mm), ensuring proper fitment and clearance on compatible Mini models.

The rotor includes a floating disc mounting design and accommodates five lug holes with a diameter of 0.654 inches (16.600 mm). The center hole diameter is 3.110 inches (79.000 mm), and the mounting bolt hole circle diameter is 4.724 inches (120.000 mm). This rotor does not include an ABS tone ring or bearings, so those components must be sourced separately if required.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Mini Cooper Countryman and Cooper Paceman
• Addresses brake pulsation or vibration issues caused by uneven rotor surfaces
• Restores proper rotor thickness to maintain braking efficiency and safety
• Eliminates noise caused by rotor surface irregularities
• Provides a direct fit solution for standard disc brake rotor replacement

Installation Notes and Tips

• Verify rotor thickness before installation to ensure it meets minimum discard thickness
• Clean rotor surface and hub mounting area to prevent uneven contact
