How to Flush Brake Fluid: Complete Guide

🔑Brake fluid should be flushed every 2-3 years to remove water and prevent brake failure.

🚗Flushing the brake fluid is essential when replacing brake calipers to avoid contaminating the new calipers.

🌡️Brake fluid absorbs water, which lowers its boiling point and may result in brake fade under high temperatures.

💧Water-contaminated brake fluid can boil and create compressible voids, causing loss of brake effectiveness.

🛠️The two-person method and the one-person method are the two common ways to bleed brakes effectively.

How often should brake fluid be flushed?

—Brake fluid should be flushed every 2-3 years or as recommended by your vehicle manufacturer.

Can I flush the brake fluid myself?

—Yes, you can flush the brake fluid yourself by following the step-by-step process outlined in this video.

Why is water contamination a concern in brake fluid?

—Water in brake fluid lowers its boiling point and can lead to brake fade and loss of braking effectiveness.

What is the difference between the two-person method and the one-person method of bleeding brakes?

—The two-person method requires someone to press the brake pedal while another person opens and closes the bleeder valve. The one-person method uses a bottle system to prevent air from entering the system while you press the brake pedal.

Can I reuse brake fluid that I drained from the system?

—It's best to use fresh brake fluid when performing a brake flush to ensure optimal performance and avoid introducing contaminants.
