Analysis of Scratching Causes of Brake Pads and Brake Drums
1. The brake drum is a brittle gray cast iron material.
2. The brake drum is a cast iron piece with a shape similar to a tambourine, which is fixed with the tire and rotates at the same speed. When braking, hydraulic pressure is used to push the brake shoe to contact the inner edge of the brake drum, and the frictional force generated by the contact suppresses the rotation of the tire to achieve the purpose of braking. Drum brakes are composed of brake base plate, brake cylinder, brake shoes and other related connecting rods, springs, pins, and brake drums.
3. In order to ensure that the friction lining has a good braking torque, it is recommended to process the inner circular smooth hub of the brake hub when replacing the new friction lining, and the iron filings after processing must be cleaned up.
