What is the adjustment method for drum brakes?
1 Answers
Drum brakes are adjusted by: tightening the nut below the brake pedal. The function of brakes is to reduce speed or bring the vehicle to a stop. Their working principle involves converting the kinetic energy of the moving vehicle into heat energy through friction between the brake shoes and brake drum, as well as between the tires and the ground, thereby slowing down or stopping the vehicle. Causes of brake failure include: 1. Contaminants or poor sealing in the brake master cylinder; 2. Failure of the vacuum booster pump; 3. Dirty brake fluid; 4. Leaking brake master cylinder or wheel cylinder; 5. Leaks in the air reservoir or pipe connections; 6. Severe overloading; 7. Carbonization of the brake drum; 8. Insufficient brake fluid in the brake master cylinder; 9. Wear of the brake master cylinder piston.
