MPA Electrical BR30083G Disc Brake Rotor - Rear

Rear Brake Rotor for Lexus RX Applications

The MPA Electrical Black Series Coated Rotor BR30083G is a rear disc brake rotor built for Lexus RX models that need consistent stopping performance and corrosion protection. It combines a coated finish with a vented rotor design to support cooling, smooth braking, and reduced rust exposure in demanding driving conditions.

Black Series Coated Rotor Details

The Black Series Coated Rotor line focuses on OE-style replacement fit and durable surface protection. On BR30083G, the coated disc and coated hat help resist rust, while the smooth surface supports even pad contact. This rotor is a standard replacement part for rear brake service on Lexus RX350, RX350L, RX450h, and RX450hL applications.

• Part number BR30083G for rear brake service
• Coated disc finish and coated hat finish for added rust resistance
• Vented rotor construction for improved heat management
• OE-style vane design to support cooling and braking consistency
• Smooth surface type for stable pad engagement
• Standard replacement grade for direct brake maintenance
• 5-lug mounting pattern with no ABS tone ring included

Detailed Product Overview

MPA Electrical BR30083G is engineered as a rear disc brake rotor for 2016-2022 Lexus RX350, 2018-2022 Lexus RX350L, 2016-2022 Lexus RX450h, and 2018-2022 Lexus RX450hL. The rotor uses a vented design and OE-style vane layout to help move heat away from the braking surface, which supports more consistent pedal feel and stopping response. Its Q-Shield protective coating is intended to help the rotor resist rust in harsh environments and maintain a cleaner appearance over time.

This part number, BR30083G, is a practical choice for drivers replacing worn rear rotors on Lexus RX350 and Lexus RX450h platforms where coated brake components are preferred for corrosion control.

Common Brake Issues It Can Address

• Brake pulsation caused by worn or uneven rear rotors
• Rust buildup on exposed rotor surfaces
• Reduced braking consistency from heat-related wear
• Noisy braking from deteriorated rotor surfaces
• Loss of smooth pad contact during rear brake service

Installation Notes and Tips

Verify rotor thickness against service limits before installation. The listed nominal thickness is 0.70 in. (17.9 mm) and discard thickness is 0.65 in. (16.5 mm). Confirm rear fitment by vehicle year, model, and position before ordering. Clean the hub mounting surface thoroughly and inspect brake pads and hardware condition during rotor replacement to help maintain even braking performance.

Quality Assurance

MPA Electrical Black Series rotors are built with coated surfaces and OE-style vane design to support reliable replacement performance. The Q-Shield coating is formulated for high-temperature exposure and corrosion resistance, helping protect the rotor in harsh operating conditions.
