Product Line Details: Black Series Coated Rotor

The Black Series Coated Rotor line by MPA Electrical focuses on providing rotors with a protective coating on both the disc and hat surfaces. This coating helps reduce corrosion and extends the rotor's service life, especially in environments prone to moisture and road salt. The BR77504G rotor benefits from this coating, offering a balance between durability and performance for Mitsubishi Lancer vehicles.

Technical Description and Specifications

This disc brake rotor is vented, allowing air to flow between the rotor surfaces to dissipate heat more effectively during braking. The nominal thickness measures 0.87 inches (22.0 mm), with a discard thickness of 0.79 inches (20.0 mm), indicating when the rotor should be replaced to maintain safe braking. The smooth surface finish ensures consistent pad contact and braking response. The rotor includes five stud holes with a mounting bolt hole diameter of 0.488 inches (12.4 mm), matching the Mitsubishi Lancer's specifications. The rust-resistant coating on both the disc and hat surfaces helps prevent corrosion, which can affect braking efficiency and rotor longevity.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Mitsubishi Lancer models
• Addressing rotor corrosion issues due to environmental exposure
• Improving heat dissipation to reduce brake fade during extended use
• Restoring smooth braking performance by replacing damaged or uneven rotors
• Maintaining proper rotor thickness for safe braking operation

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets the nominal thickness specifications. Clean the mounting surface and hub to prevent uneven rotor seating. Use the correct torque specifications for the five mounting bolts with 0.488 inch (12.4 mm) diameter holes. Since this rotor does not include bearings or ABS tone rings, verify compatibility with your vehicle's existing components. Proper installation will help maintain braking performance and rotor longevity.

Quality Assurance and Warranty

The MPA Electrical Black Series Coated Rotor BR77504G is a new, standard replacement part manufactured to meet OEM specifications for Mitsubishi Lancer vehicles. The rust-resistant coating and vented design contribute to consistent braking performance and durability. Warranty details should be confirmed with the supplier or manufacturer, as they may vary.
