How much water in brake fluid is OK?

Can I change brake fluid myself?
You can’t do a complete brake fluid flush yourself, but you can do the next best thing—a fluid swap. This procedure won’t replace all the old fluid with fresh, but you’ll introduce enough new fluid to make a difference.

Can brake fluid run out?
If your vehicle runs out of brake fluid it will run out of brakes. Brake fluid is not normally consumed. The level in the reservoir will drop as the brake pads are consumed/worn but when the pads are replaced and the pistons pushed back to the home position the level will rise in the reservoir.
Will old brake fluid cause spongy brakes?
Since brake lines are made of steel tubing, they can become corroded by rust. Over time, rust can cause small holes to develop, allowing brake fluid to leak out. The loss of brake fluid leads to a loss of hydraulic pressure, so the brake pedal will feel soft or low and go to the floor.
How much is brake change at Walmart?
However, Walmart does provide an at-home brake replacement service by Wrench Mobile Mechanic Service starting from $160. Walmart also sells brake pads and service tool kits for sedan and 4X4 models.

What causes brake fluid to black?
Brake fluid color usually goes darker as it gets old. This mainly occurs because brake fluids are hygroscopic, which means they are designed to absorb water. It won’t just absorb water, but the moisture from that makes its way through rubber brake lines.
