Raybestos R-Line Product Line Details

The R-Line from Raybestos focuses on delivering dependable replacement brake components that meet OEM specifications. This product line emphasizes consistent quality and fitment, making it a practical choice for maintaining braking performance on vehicles such as the Mitsubishi Space Star and Volvo S40 and V40. The 980085R rotor is part of this line, offering vented rotor technology to help manage heat buildup during braking.

Technical Specifications and Features

The 980085R disc brake rotor features a vented design that enhances cooling by allowing air to circulate between the rotor surfaces. This helps reduce brake fade during extended use. The rotor’s nominal thickness is 0.394 inches (10 mm), with a discard thickness of 0.331 inches (8.4 mm), indicating when replacement is necessary to maintain safe braking. The overall diameter of 10.236 inches (260 mm) and height of 1.614 inches (41 mm) ensure compatibility with the specified Mitsubishi and Volvo models. The rotor mounts using four bolt holes arranged on a 114.3 mm (4.5 inch) bolt circle, with a center hole diameter of 3.543 inches (90 mm) for proper hub alignment.

Applications and Problem Solving

• Replacement for worn or warped rotors on Mitsubishi Space Star and Volvo S40, V40
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Helps restore braking efficiency and pedal feel
• Prevents brake fade by improving heat dissipation with vented design
• Ensures proper rotor thickness for safe braking performance

Installation Notes and Tips

When installing the Raybestos R-Line 980085R rotor, ensure the mounting surface and hub are clean and free of debris.
