Using expired or contaminated brake fluid can lead to reduced braking efficiency, corrosion of brake system components, and potential brake failure. Moisture absorption over time lowers the boiling point of the fluid, increasing the risk of vapor lock and dangerous driving conditions.

Common Questions About Brake Fluid Safety

CAUTION

Is it safe to use brake fluid after the expiration date?

Brake Fluid past its labeled date may still function but could have reduced effectiveness. The manufacturer's date indicates guaranteed performance. After this date, the product may separate, lose potency, or not perform as expected. Check for changes in color, consistency, or smell before use.

CAUTION

What if brake fluid looks different than when purchased?

Changes in color, consistency, or separation in brake fluid typically indicate the product has degraded. While this may not pose a safety hazard for non-food items, it usually means reduced effectiveness. If the product has solidified, separated significantly, or changed color dramatically, it is best to replace it.
