• Drum-in-hat type rotor with 5 mounting bolt holes
• Outside diameter of 12.32 inches (313 mm) and overall height of 2.2 inches (56 mm)
• Nominal thickness of 0.44 inches (11.1 mm) with discard thickness at 0.37 inches (9.5 mm)
• Non-directional brake surface for flexible installation

Technical Details and Construction

The DuraGo BR31318-01 rotor features a full cast iron construction designed to withstand the rigors of daily driving. Its solid rotor design, without slots or cross-drilling, provides a stable braking surface that minimizes noise and vibration. The rust-resistant coating helps protect the rotor from corrosion, which is especially beneficial in humid or wet environments. This rotor is a drum-in-hat type, integrating the parking brake drum into the rotor assembly, compatible with specific Acura MDX and Honda Pilot models. The rotor includes five mounting bolt holes with a bolt circle diameter of 114.3 mm (4.5 inches) and a center hole diameter of 64.1 mm (2.52 inches), ensuring proper fitment and secure installation.

Compatible Vehicles and Applications

This disc brake rotor is compatible with the following vehicles:

• Acura MDX
• Honda Pilot

It is designed to replace worn or damaged rotors, restoring braking efficiency and safety. Common issues addressed by this rotor include:

• Brake pulsation or vibration during braking
• Excessive rotor wear or scoring
• Corrosion or rust buildup on the rotor surface
• Reduced braking performance or noise
• Warped or uneven rotor surfaces

Installation Notes and Tips

When installing the DuraGo BR31318-01 rotor, ensure the rotor thickness is above the discard thickness of 0.37 inches (9.5 mm) to maintain safe braking performance. Clean the rotor surface before installation to remove any protective coatings or contaminants. Verify that the mounting bolt holes align correctly with the vehicle hub and torque bolts to manufacturer specifications. Since this rotor is non-directional, it can be installed on either side of the vehicle without concern for rotation direction.
