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 coating extends the rotor's service life, especially in environments prone to moisture and road salt exposure. The BR72177G rotor benefits from this coating on both the disc and hat surfaces, maintaining structural integrity and appearance over time.

Technical Specifications and Features

This disc brake rotor features a vented design that enhances heat dissipation during braking, reducing the risk of brake fade. The nominal thickness measures 1.10 inches (28.0 mm), with a discard thickness of 1.04 inches (26.4 mm), indicating when the rotor should be replaced to maintain safe braking performance. The smooth surface finish ensures even brake pad wear and consistent stopping power. The rotor includes five mounting lug holes with a bolt circle diameter of 127.0 mm (5.000 inches) and a center hole diameter of 72.0 mm, matching the specifications required for Jeep Wrangler and Wrangler JK models.

Applications and Problem Solving

• Replacement for worn or warped rotors on Jeep Wrangler and Wrangler JK vehicles
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Prevents rust-related rotor degradation in humid or salted road conditions
• Improves braking consistency by maintaining proper rotor thickness
• Supports safe braking performance during off-road and daily driving

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets the nominal thickness specifications. Clean the rotor surface to remove any protective oils or residues prior to mounting. Verify compatibility with your Jeep Wrangler or Wrangler JK by matching the part number BR72177G and lug pattern. Use proper torque specifications for mounting bolts to avoid rotor warping. This rotor does not include bearings or ABS tone rings, so verify existing components are compatible.

Quality Assurance and Warranty

The MPA Electrical Black Series Coated Rotor BR72177G is a new, standard replacement grade rotor designed to meet OEM specifications. The rust-resistant coating on both the disc and hat surfaces helps maintain rotor integrity over time. Warranty details should be confirmed with the distributor or manufacturer, as they may vary by region.
