Brake System Flush in San Marcos, TX

About This Service

Replace old, moisture-contaminated fluid with fresh DOT-approved fluid to restore optimal hydraulic pressure and safe braking performance.

Brake fluid is hygroscopic — it absorbs moisture from the atmosphere over time. As water content rises, the fluid's boiling point drops, increasing the risk of vapor lock under hard braking. Contaminated fluid also accelerates corrosion inside calipers, wheel cylinders, and ABS modulators. A complete flush removes the old fluid and replaces it with fresh DOT-approved fluid, restoring full hydraulic pressure and protecting internal components.

• Removes moisture-contaminated fluid from the entire system
• Restores proper hydraulic pressure and pedal firmness
• Protects calipers and ABS components from internal corrosion
• DOT 3, DOT 4, and DOT 5.1 fluids available
