How often should the brake fluid in a car be changed?
1 Answers
Brake fluid in a car should be changed every 40,000 kilometers or every 3 years. Brake fluid, also known as hydraulic brake fluid, is a functional liquid that transmits pressure in the vehicle's braking system, enabling the braking action on the wheels. Brake fluid does not undergo chemical reactions, is unaffected by high temperatures, and does not corrode, soften, or expand metals and rubber. If brake fluid is not changed for a long time, it can lead to reduced braking force, causing air resistance in the brake lines, which affects braking performance. It can also corrode the brake lines, damage the internal valves of the anti-lock braking hydraulic assembly, and cause wear to the pistons and rubber cups in the brake master cylinder, resulting in contaminated brake fluid.
