Lexus GS400 brake rotors are important components of your vehicle’s disc braking system that perform several functions. Located at each of your wheels, GS400 brake rotors are one-piece metal discs that work with your brake pads to generate friction, which is used to stop your vehicle. When your brake pedal is pressed down, the frictional surface of your brake pads is brought into contact with your metal brake rotors, and the simultaneous pressure of the brake pads on either side of your rotors serves to stop the rotation of your wheels.

In addition to generating friction, your brakes also have to have some way to cool down, since the process of stopping generates heat. Your Lexus GS400 brake rotors help to keep your brakes cool by dissipating heat through their rapid spinning, which helps to prevent brake fade.

Finally, your GS400 brake rotors help to keep your brakes clean by throwing off water and dirt as they spin. Keeping your brake rotors in good condition depends largely on the condition and the type of brake pads you have installed. If you have metallic brake pads, they are going to cause more rapid rotor wear. Soft brake pads can also damage your Lexus GS400 brake rotors if you do not change them when the depth of the lining drops to between an eighth and a quarter of an inch. If your brakes are shuddering or pulling to one side, or if you hear a loud, metallic grating sound coming from your brakes, these are typically signs that your GS400 brake rotors are damaged and need to be replaced. Keep in mind that you should change your brake pads whenever you replace your rotors.You will find the brake rotors and brake pads you need right here in our online catalogue.
