Product Line Details: Black Series Coated Rotor

The Black Series Coated Rotor line by MPA Electrical focuses on providing rotors with protective coatings on both the disc and hat surfaces. This coating helps resist rust and corrosion, which is particularly beneficial for vehicles like the Buick Regal and Cadillac XTS that may be exposed to moisture and road salts. The vented design supports effective heat management, reducing the risk of brake fade during extended use.

Technical Specifications and Features

This disc brake rotor (part number BR72030G) is designed as a direct replacement for specific Buick and Cadillac models. It features a nominal thickness of 1.18 inches (30.0 mm) and a discard thickness of 1.12 inches (28.5 mm), ensuring it meets OEM standards for durability and performance. The rotor is vented to allow air flow between the rotor surfaces, which helps dissipate heat generated during braking. Both the disc and hat surfaces are coated to provide rust resistance, extending the rotor's service life. The smooth surface finish supports consistent brake pad contact and reduces noise.

Applications and Problem Solving

• Replacement for worn or warped rotors on Buick Regal and Cadillac XTS
• Addresses rotor corrosion issues caused by road salt and moisture exposure
• Helps reduce brake fade through improved heat dissipation with vented design
• Restores smooth braking performance by replacing rotors with uneven surfaces
• Compatible with vehicles requiring a 5-lug wheel pattern and 67.4 mm center hole diameter

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it is above the discard thickness of 1.12 inches (28.5 mm). Clean the hub surface thoroughly to prevent uneven rotor mounting. This rotor does not include ABS tone rings or bearings, so verify compatibility with your vehicle’s existing components. Proper torque specifications should be followed when tightening mounting bolts to avoid rotor warping.

Quality Assurance and Warranty

The MPA Electrical Black Series Coated Rotor BR72030G is a new, standard replacement grade rotor designed to meet OEM specifications. The rust-resistant coating and vented design contribute to consistent braking performance and extended rotor life. Warranty details should be confirmed with the distributor or manufacturer, as they may vary.
