2021-2025 Toyota Wheel Film for Brake Rotor Rust Prevention TSB

Introduction to Toyota Brake Rotor Rust Prevention

Toyota has issued Technical Service Bulletin (TSB) T-SB-0038-24 to inform technicians and owners about a new method for Toyota Brake Rotor Rust Prevention. This bulletin, dated April 19, 2024, details the use of a specialized wheel film to protect brake rotors from rust during vehicle transportation and storage. This film replaces the older cardboard-type anti-rust covers, offering enhanced protection against weather elements and initial rust formation before a vehicle is delivered to the customer.

This TSB, T-SB-0038-24, supersedes Service Bulletin No. PD017-04, which is now considered obsolete. The information in the new bulletin has been fully updated to reflect the current procedures.

Important Warnings and Owner Information

Owners and technicians should be aware of specific instructions regarding the wheel film:

• "Retain the wheel film on the disc wheel during vehicle display and storage." This ensures continued protection for the brake rotors.
• "If the vehicle will be stored after Pre-Delivery Service (PDS), do NOT remove the wheel film right away." The film should remain on the wheel for as long as possible to maximize its protective benefits.
• The wheel film should only be removed "just prior to the delivery to customers."
• When removing the film, especially in cold conditions (below 0°C or 32°F), there's a risk that the film may tear. To prevent this, it's advised to warm the film using methods such as splashing hot water, applying a cotton cloth soaked in hot water, using a heat gun, an infrared heater (lamp) for paint, or a steam car wash. Parking the vehicle indoors for an extended period can also help.
• "Do NOT overheat the film and wheel" when using warming methods like a heat gun or infrared heater.
• If adhesive residue remains on the disc wheel after removal, it can be cleaned with a soft cloth dipped in ethyl alcohol (ethanol). "Do NOT use thinner to remove the adhesive residue" as it may damage the wheel finish.

Wheel Film Removal Instructions

Removing the wheel film is a straightforward process, but care should be taken, especially in cold weather, to ensure a clean removal. The procedure involves two main steps:

1. Firmly hold the outer end of the wheel film.
2. Carefully pull OFF the wheel film from the wheel.

As noted in the warnings, if the ambient temperature is below 0°C (32°F), warming the film is crucial to prevent tearing. This can be done by applying hot water, a warm, wet cloth, a heat gun (carefully, to avoid overheating), an infrared heater, or by parking the vehicle indoors.

Adhesive Residue Cleanup

Should any adhesive residue be left on the disc wheel after the film is removed, it can be easily cleaned. Use a soft cloth dampened with ethyl alcohol (ethanol) to wipe away the residue. It is critical to avoid using thinner or other harsh solvents, as these can potentially damage the wheel's finish.

Film Disposal Information

The polyethylene wheel film should be disposed of according to local regulations. Toyota notes that polyethylene film will not generate harmful gases when it is burned, making it a relatively safe material for waste management.
