About Scion Brake Drum
Inside your vehicle are Toyota brake drums-a cast iron or aluminum housing that's bolted onto your car's wheel. Unlike your brake disc which uses brake pads, these drums stops your vehicle by using brake shoes. Your braking system uses friction that's generated by the rubbing motion between your brake shoes and brake drums to convert your vehicle's kinetic energy into heat. That is why it's important for you to keep your Toyota brake drums in great shape.
