Black Series Coated Rotor Product Line Details

The Black Series Coated Rotor line by MPA Electrical focuses on providing rotors with protective coatings to resist rust and corrosion. This product line is tailored for drivers seeking a standard replacement rotor that offers extended service life through its coated disc and hat surfaces. The BR42250G model exemplifies this approach by combining vented rotor design with a durable coating to help maintain braking efficiency over time.

Technical Specifications and Features

The BR42250G disc brake rotor features a vented design that promotes effective heat dissipation, reducing the risk of brake fade during extended use. The nominal thickness measures 1.54 inches (39.0 mm), with a discard thickness of 1.47 inches (37.4 mm), ensuring clear maintenance thresholds. Both the disc and hat are coated to provide rust resistance, which is critical for maintaining rotor integrity in environments prone to moisture and road salt exposure. The smooth surface finish supports consistent brake pad engagement, contributing to stable braking performance.

Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Upgrading corroded rotors to prevent premature wear
• Addressing brake fade due to overheating with vented rotor design
• Improving braking consistency on vehicles experiencing uneven pad contact
• Maintaining rotor longevity in humid or salty environments

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets the nominal thickness specifications. The BR42250G requires a mounting bolt hole circle diameter of 163.1 mm and a center hole diameter of 139.4 mm. Proper torque specifications should be followed for the 10 lug holes with 12.9 mm mounting bolt hole diameter. This rotor does not include ABS tone rings or bearings, so verify compatibility with your vehicle’s braking system before installation.
