How do I know when to replace my Brake Fluid?
Brake fluid should be replaced every 2 years or 24,000 miles regardless of appearance, as it absorbs moisture over time. Signs of degraded fluid include a spongy pedal, reduced braking performance in repeated hard stops, or the fluid testing above 3.5% water content.
What tools do I need to replace a Brake Fluid?
Tools needed: syringe or turkey baster for fluid removal, funnel, brake bleeding kit (or pressure bleeder). Difficulty: Easy DIY. Safety warning: Brake fluid is hygroscopic -- it absorbs moisture over time, lowering its boiling point. Use the DOT grade specified by your manufacturer. Brake fluid is corrosive to paint and skin.
