Detailed Product Description

The AR8924EVC rotor features a full cast, vented design that improves heat dissipation during braking, reducing the risk of brake fade. Its smooth surface ensures consistent pad contact and braking performance. The rotor’s nominal thickness of 38.1 mm and discard thickness of 36.1 mm provide clear service limits for maintenance. With a 395.0 mm outside diameter and 10 lug holes on a 163.3 mm bolt circle diameter, this rotor is engineered to fit specific rear brake assemblies requiring these dimensions.

Common Applications and Issues Addressed

• Replacement for worn or warped rear disc brake rotors
• Corrosion damage repair due to rust buildup on rotors
• Improved braking consistency for vehicles experiencing brake fade
• Restoring proper rotor thickness to maintain braking efficiency
• Addressing noise or vibration caused by uneven rotor surfaces

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets the nominal thickness of 38.1 mm and is above the discard thickness of 36.1 mm. Clean the rotor surface to remove any protective coating residue before mounting. Verify compatibility with your vehicle’s rear brake system by checking the 10-lug hole pattern and 163.3 mm bolt circle diameter. Proper torque specifications should be followed when securing the rotor to avoid warping.
