Auto Systems and Repair

Brake fluid is a specially formulated fluid that transmits the pressure generated by the master cylinder to the calipers and/or wheel cylinders when the brake pedal is pressed. 

Symptoms of Wear or Failure

• Brake light may illuminate
• Soft or spongy brake pedal

Related Repair Advice

• In most modern vehicles, the brake fluid level is monitored via a sensor in the brake fluid reservoir
• Brake fluid can damage a vehicle's paint and trim; any spills should be cleaned up immediately by flushing the area with water (no soap is needed)
  
• Brake fluid should be replaced if the fluid is dirty or if the brake system shows any evidence of rust or corrosion
• Brake fluid absorbs moisture and loses its effectiveness over time; we recommend the brake fluid be replaced every two years as preventative maintenance
• We recommend having the brake hydraulic system flushed any time a component in the hydraulic system is replaced or if the hydraulic system is opened
