You must flush and change the fluid for your brakes every two years. It is possible to replace your own brake fluid Nissan Altima. However, service centers now do this using brake flushing machines. If you discover a leak in the brake fluid, or you need to flush your brakes then you’ll need to replenish the level of brake fluid in the master cylinder to its correct level. There are a few things you need to know about purchasing as well as applying brake fluid:

• Make sure you use the best brake fluid made by a famous brand: Many vehicles call for either D.O.T. 3 or D.O.T. 4 fluid. D.O.T. 5 is now available and it’s a fantastic improvement since it doesn’t eat paint and absorb water. However, since D.O.T. 5 doesn’t absorb it the water that enters your brake system may create tiny pools that could ruin your brakes.
• Exposure to air rapidly affects the brake fluid. Airborne oxygen in the air can oxidize it and decreases the boiling point. The brake fluid has an inclination for moisture. The liquid water in the air could mix with brake fluid decreasing the boiling point of the fluid and, in cold weather, creating crystals of ice that make the braking process difficult. The addition of water vapor into your brake system could cause rust to the system and produce acids that damage the cylinders of your wheels and master cylinders and can corrode the brakes, making them malfunction or not in any way. It also can cause irreparable damage to components of ABS and other costly brake systems.

If you’d like to change the brake fluid on your own take these steps:

1. Take the old filthy fluid from the reservoir for the master cylinder. Utilize an inexpensive turkey baster to do this.
2. Make use of a cloth with no lints to clean off the reservoir. Only do this if you are able to be able to get in there.
3. Inject new brake fluid into the reservoir only until it is at”Full” line “Full” line, replace the cap that seals the reservoir. When you flush the brake lines (which you can learn about elsewhere on this website) the new fluid is pushing the old fluid from the system. Continue to flush the brakes until you observe clear, clean fluid flowing out of the screw for the bleeder.
