How often should the brake fluid be replaced in the Envision?
2 Answers
The brake fluid replacement interval for the Buick Envision is every 30,000 kilometers. If you need to replace the brake fluid for the Buick Envision, the replacement tutorial is as follows: 1. Extract the old oil from the brake fluid reservoir in the engine compartment. Wait for about ten seconds to complete the extraction, then use the extraction pump to remove the fluid and air from the brake fluid lines. 2. Connect a soft rubber tube to the exhaust port and start extracting the brake fluid. While extracting the old brake fluid, pour new oil into the filling port to push out the old oil and prevent air from increasing in the lines due to lack of fluid. 3. After the extraction is complete, add brake fluid to the appropriate level, secure the cap, and start the car to test the brake performance.
I've been driving the Envision for several years, and brake fluid replacement is not something to be taken lightly. Generally, it's recommended to replace it every two years or every 40,000 kilometers, depending on what the owner's manual specifies. This is because brake fluid absorbs moisture from the air, and over time, it can corrode the metal components of the braking system, leading to reduced braking performance—such as longer stopping distances or even failure in emergencies. I make it a habit to check the condition of the brake fluid during annual maintenance, using a simple moisture test strip. If the color darkens or the moisture content is high, I replace it ahead of schedule. The Envision's braking system is quite responsive, and keeping it in good condition ensures a safer drive and extends the lifespan of other components. Always go to an authorized service center for the replacement—don't skimp on safety; it's more important than anything else.
