Question:

What should brake linings not be?

A Loose, thin, or soaked with oil or grease.

explanation

Brake linings should not be loose, thin, or soaked with oil or grease.

Loose brake linings: Loose brake linings can result in reduced braking efficiency and poor performance. It is important for the brake linings to be securely attached to the brake shoes or pads to ensure proper contact and effective braking.
Thin brake linings: Brake linings that are excessively thin may not provide sufficient friction material for effective braking. Thin linings can result in reduced stopping power, increased stopping distances, and potential overheating of the braking system. Regular inspection and replacement of worn brake linings are crucial for maintaining proper braking performance.
Brake linings soaked with oil or grease: Brake linings contaminated with oil or grease lose their friction characteristics and become less effective in generating the necessary braking force. Oil or grease on the brake linings can lead to reduced grip and braking performance, potentially causing safety issues. Contaminated brake linings should be thoroughly cleaned or replaced as necessary.
