Detailed Product Description

This Centric disc brake rotor is a solid type, meaning it does not have vented channels, which is typical for certain Mercedes-Benz models where solid rotors are specified. The smooth surface finish ensures even pad contact and braking efficiency. With a nominal thickness of 0.354 inches (9.000 mm) and a discard thickness of 0.287 inches (7.300 mm), this rotor maintains structural integrity and safety margins throughout its service life. The rotor’s outside diameter of 10.945 inches (278 mm) and overall height of 2.295 inches (58.300 mm) are designed to match OEM dimensions precisely. The five lug holes and mounting bolt circle diameter ensure proper fitment on the specified Mercedes-Benz vehicles.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Mercedes-Benz 300SL, 500SL, SL320, and SL500
• Addresses brake pulsation caused by uneven rotor surfaces
• Restores braking performance diminished by rotor thickness below discard limits
• Eliminates noise and vibration from damaged or scored rotors
• Ensures safe braking by maintaining OEM rotor specifications

Installation Notes and Tips

• Verify rotor thickness before installation; replace if below discard thickness of 0.287 inches (7.300 mm)
• Ensure mounting surfaces and hub are clean and free of debris
• Torque lug nuts to manufacturer specifications to avoid rotor warping
• Check compatibility with vehicle ABS system; this rotor does not include an ABS tone ring
• Inspect brake pads and replace if worn to ensure optimal rotor performance
