Brake Fluid Exchange Overview 

The service is frequently called a brake flush, and on the surface, it’s a simple process. The existing brake fluid is drained from the system and replaced with fresh, new fluid. As part of the service, the brake lines will be bled and inspected. In fact, the entire brake system will be reviewed and tested. It’s an integral part of maintaining your brakes. Brake fluid exchanges are typically listed as part of the recommended scheduled service in your owner’s manual. While the service's timing will vary by model, the average is to have the service completed every 30,000 miles or two years.

What Does a Brake Fluid Exchange Do for My Lexus?

Brake fluid is essential to providing stopping power for your vehicle. The brakes operate with hydraulic pressure, and your brake fluid is the agent that provides the pressure. Brake fluid is specifically designed and engineered to work in these systems, but over time, the fluid will collect contaminants, which will degrade its performance. Dirt and water are the primary contaminants. They can change the hydraulic pressure of the fluid and its boiling point. Both of these issues affect the brake pedal's responsiveness and the vehicle’s ability to stop effectively.
