Brake Fluid's Critical Role

Brake fluid is vital for safe braking, transferring pedal force to the brakes. Degraded fluid reduces braking effectiveness.

Recognizing Brake Fluid Issues

  • Mushy brake pedal: A soft pedal may indicate contaminated brake fluid.
  • Anti-lock brake system light: Modern vehicles may alert you when brake fluid is low or compromised.
  • Inconsistent braking: If braking feels inconsistent or delayed, it’s time for a check-up.
  • Discolored fluid: Healthy brake fluid is typically clear or light yellow; dark fluid signals contamination.

Brake Fluid Replacement Frequency

Most manufacturers recommend changing brake fluid every two to three years or every 30,000 miles. However, driving habits and local conditions—like St. Louis' fluctuating weather—can impact this timeline. Regular brake inspections will help determine when it’s time for a change.

DIY vs. Professional Brake Fluid Maintenance

Checking fluid levels is simple, but replacement needs professional bleeding.
