Detailed Product Features and Specifications

The BR31294 rotor features a cast iron construction that balances durability with effective heat management. Its vented design allows air to flow between the rotor surfaces, reducing brake fade during extended use. The rotor measures 312 mm (12.28 inches) in outside diameter and has an overall height of 68.1 mm (2.68 inches), ensuring proper fitment on compatible vehicles. The nominal thickness is 18 mm (0.71 inches), with a discard thickness of 16 mm (0.63 inches), providing clear service limits for maintenance. This rotor includes a drum-in-hat design, integrating the parking brake drum into the rotor assembly, which is common for Lexus GX470 and Toyota Sequoia brake systems. The mounting bolt pattern includes 6 holes with a bolt circle diameter of 139.7 mm (5.5 inches) and bolt hole diameter of 14.4 mm (0.57 inches). The center hole diameter is 106 mm (4.17 inches), matching OEM specifications for proper hub fitment. Note that this rotor does not include an ABS tone ring and does not have rust-resistant coating.
