The best fluid for your vehicle ought to transfer the force effectively, lubricate the calipers, have a high boiling point, and offer resistance to corrosion.

Fill the master cylinder with the brake fluid, and then ask someone to start the vehicle and press the brake pedal.

The bleeder screw on one of the wheels should be loosened to allow air to exit completely until the brake fluid starts to flow. You ought to repeat this process for all wheels and then refill the master cylinder with brake fluid.

The brake fluid should be checked as well as changed after about 25000 miles. Bleeding the system improves the efficacy of the system, and it should be done after every two or three years of your vehicle’s life span. After draining the brake fluid, you should test the functionality of your brakes before using the car again.

Unfortunately, there is no sure way of protecting brake lines from rust, but it can be significantly reduced by oiling and easing as well as regular maintenance.
