What This Brake Kit Helps Address

• Brake pad wear that reduces stopping consistency
• Rotor scoring, vibration, or uneven braking feel
• Service intervals that require both rotors and pads
• Front and rear brake refreshes on BMW 330i, BMW M340i, and Toyota GR Supra applications
• Replacement needs for mixed rotor designs listed in the fitment notes

Installation Notes and Tips

Confirm the rotor design noted for your vehicle before ordering, especially on BMW xDrive and Toyota GR Supra applications where original design aluminum hat and optional full cast rotor setups are both listed. Verify axle position, rear disc size where specified, and match the kit to the exact model year and drivetrain configuration. Part number 4504-31140 should be checked against the vehicle’s brake package before installation.
