Tesla Model S/X Rear Brake Rotor 1420631-00-A Low Dust Ceramic

Basic Information

• Model Compatibility: It is applicable to Model S Plaid, Model X Plaid, and Model S produced in 2021 and later.
• Part Number: 1420631 - 00 - A, which is a unique identification code for this brake rotor, used to accurately match the corresponding model and part.

Design and Build Quality

• Material Selection: Usually, high - quality cast iron or other alloy materials are used. These materials have the characteristics of high strength, wear resistance, and good heat dissipation performance, which can withstand high temperatures and frictions generated during braking and ensure the service life and performance of the brake rotor.
• Structural Design: Some brake rotors adopt a two - piece structure, consisting of a central hat section and a disc. The central hat section is often made of 6061 - T6 aircraft - specification aluminum, which is lightweight and has high strength. The disc is made of proprietary cast iron and is equipped with curved directional vanes to improve the cooling effect. There is also a floating mount system between the rotor and the hat, which can reduce noise and vibration during operation.

Functionality and Benefits

• Core Function: The main function is to work with the brake caliper and brake pads to achieve the braking function of the vehicle. When the driver steps on the brake pedal, the brake caliper clamps the brake pads, and the brake pads rub against the surface of the brake rotor to generate friction, which slows down or stops the rotation of the wheels, thereby achieving the purpose of braking the vehicle.
• Enhanced Braking Performance: The design and material selection of the brake rotor are beneficial for improving the braking performance of the vehicle. The larger diameter and appropriate thickness of the rotor can increase the braking torque and improve the braking efficiency. The excellent heat dissipation performance can effectively reduce the temperature of the brake system during braking, avoid brake fade caused by overheating, and ensure the stability and reliability of braking.
• Improved Driving Safety: Reliable braking performance is crucial for driving safety. The high - quality rear brake rotor can ensure that the vehicle has a good braking response in various driving conditions, shorten the braking distance, and thus improve the safety of the driver, passengers, and the vehicle.

Installation and Maintenance

• Installation: The installation of the rear brake rotor requires certain professional skills and toolsTesla. It is recommended to install it at a professional Tesla service center or by a trained mechanic特斯拉中国. During the installation process, it is necessary to pay attention to the correct installation position and torque of each part to ensure that the brake rotor is installed firmly and can work normally.
• Maintenance: Regular inspection of the brake rotor is an important part of vehicle maintenance. Check whether there is wear, cracks, or deformation on the surface of the brake rotor regularly. If abnormal wear or damage is found, the brake rotor should be replaced in a timely manner. In addition, keeping the brake system clean and ensuring the normal operation of the brake fluid can also help extend the service life of the brake rotor.
