Brake drums are the key elements of the friction pairs. When the brake pedal is pressed, they interact with brake shoes and stop the vehicle. They are to be replaced when the diameter of their working surface reaches the maximum values. The degree of permissible wear is indicated by the vehicle manufacturer in the service manual.
What you should know about replacing brake drums
- The symptoms of the components wear include squealing and grinding noise when the pedal is pressed, vehicle pulling to one side during braking, increased braking distance. Additional signs are increased travel of the brake pedal, its shuddering, and steering wheel vibration when trying to stop the vehicle.
- Components of the brake system should be installed at a service station. Car owners should never alter its design.
- The components are replaced in pairs per axle. Besides, it is necessary to install new brake shoes, springs, and fasteners. It is, therefore, more cost-efficient to buy brake drums together with these components.
- Poor quality brake shoes, their incorrect installation, the habit of holding your foot on the brake pedal during driving, aggressive driving with frequent sharp brakings can significantly reduce the service life of these components.
