Brake Fluid Leak Color: Here's What You Need to Do.

The color of your brake fluid leak can reveal about the condition of the braking system. While brake fluid typically starts out a light yellow or amber, its color changes over time due to factors like moisture absorption. Here’s a breakdown of what different brake fluid leak colors might signify:

Dark Yellow or Brown:

This brake fluid leak color indicates that the brake fluid is absorbing moisture. Moisture in your brake fluid lowers its boiling point, which can lead to brake fade or even complete failure during heavy braking. Consider a brake fluid flush and replacement to remove moisture and ensure maximum performance.

Dark Brown or Black:
