Brake Fluid Total Fluid Exchange

The fluid used in modern hydraulic brake systems, including anti-lock brake systems (ABS) must satisfy many performance requirements. This fluid must not be compressible, must provide consistent performance over operating temperature ranges from below freezing to as high as 500°F, must provide lubrication within the brake system, must be compatible with the plastic, rubber and metal components in the system, must seal the brake system and must have a light enough viscosity to react rapidly when the brake pedal is applied.

Polyalkylene Glycol Ether based brake fluids satisfy all of these performance requirements. The one drawback to these poly-glycol brake fluids is that they readily absorb water. Water can be absorbed from humidity in the air, even through brake system seals, caps and lines, as well as anytime the brake system or a container of brake fluid is opened for any reason. As the boiling point of brake fluid decreases with increasing water content, at some point high water content could cause a loss of the hydraulic brake function at high brake system operating temperatures. Under such extreme conditions, the water in the brake system could boil, forming a vapor, which compresses when the brake pedal is applied, causing the brakes to feel "spongy" or even fail.

In addition to increasing water content leading to a decrease in the brake fluid boiling point, increasing water content and brake fluid corrosion inhibitor depletion over time allows corrosion of brake system components and "sludge" build-up. Depleted corrosion inhibitors in the presence of water will lead to corrosive attack of the master cylinder, slave cylinders and ABS components. If pistons cannot move freely, seals can also be damaged, resulting in internal and external leaks. Such corrosion and deposit build-up can potentially shorten the life of brake system components.

All of these problems can be avoided by properly determining the overall condition of the brake fluid as it relates to maintaining a safe boiling point and protecting brake system components and changing the fluid at appropriate intervals. Appropriate brake fluid change intervals are determined by either the condition of the fluid or manufacturer recommended intervals.

Auto Solutions Brake Fluid Total Fluid Exchange is performed using state of the art equipment. Auto Solutions Break Fluid is flushed through the break system. The old dirty fluid is removed and replaced with new, clean fluid leaving your break system running like new.
