How to Determine When to Replace Drum Brakes?

[DiAubrey]

Methods to determine when to replace drum brakes are: 1. For frequent brake usage, it is recommended to consider replacing drum brakes after the vehicle has traveled 80,000 kilometers; 2. For infrequent brake usage, it is recommended to consider replacing drum brakes after the vehicle has traveled 100,000 kilometers; 3. If a squeaking sound is heard when using the brakes, immediately take the vehicle to a maintenance center to inspect the braking system and replace the drum brakes. The working principle of drum brakes is: using the stationary brake shoes inside the brake drum to rub against the rotating brake drum attached to the wheel, generating friction to reduce the wheel's rotation speed. The components include: brake backing plate, brake wheel cylinder, brake shoes, related linkages, springs, pins, and brake drum.
