Brake Fluid Exchange Machine Complete Guide

I. Why is a Brake Fluid Exchange Machine Necessary?

🚗 Dangers of Aged Brake Fluid

Brake fluid serves as the pressure-transmitting medium in the braking system. Over time, it absorbs moisture from the air, leading to the following issues:

Reduced braking performance: Increased water content lowers the boiling point, potentially causing vapor lock during prolonged braking.
Corrosion of brake components: Moisture-laden fluid corrodes metal parts like master cylinders, wheel cylinders, and ABS pumps.
Safety hazards: Extended braking distances, potentially leading to brake failure in severe cases.

🧩 Therefore, manufacturers recommend replacing brake fluid every 2 years or 40,000 kilometers.

Traditional manual replacement is time-consuming and prone to air entrainment, whereas a Brake Fluid Exchange Machine performs this task faster, safer, and more thoroughly.

II. Functions and Advantages of Brake Fluid Exchange Machine

Item	Advantages
🔧 Automatic Circulating Fluid Exchange	Automatically extracts old fluid while simultaneously injecting new fluid, eliminating manual brake pedal pumping.
🩸 Prevents Air Ingestion	Sealed internal circulation system prevents air bubbles from entering brake lines.
⏱️ Saves Time and Labor	One technician completes the fluid exchange in approximately 10–20 minutes for all four wheels.
💰 Boosts Work Efficiency	Enhances turnaround rates and customer satisfaction for repair shops and auto service centers.
🧰 Intelligent Pressure Control	Automatically adjusts pressure based on vehicle model to prevent hose rupture.

Some premium models (e.g., MRCARTOOL, AUTOOL, LAUNCH) feature digital pressure gauges and multiple adapters for compatibility with various mainstream vehicles.

III. Brake Fluid Exchange Machine User Guide

⚠️ Before operation, ensure the vehicle is parked on level ground with the ignition off. Prepare compatible fluid reservoirs and connectors.

Step 1: Prepare Tools and New Brake Fluid

• Open the hood and locate the brake fluid reservoir.

• Verify the brake fluid grade to be used (e.g., DOT3, DOT4, DOT5.1).

Step 2: Connect the Brake Fluid Exchanger

• Connect the machine’s hose to the reservoir cap fitting.

• Turn on the machine and check for hose seal integrity.

Step 3: Set Pressure (Approx. 1.0–1.5 bar)

• Adjust the operating pressure to match your vehicle model.

• Inspect for air leaks.

Step 4: Initiate Flushing Cycle

• Activate the “Flushing” function. The machine will automatically extract old fluid and inject new fluid.

• Monitor the fluid color through the hose; stop when the new fluid appears clear.

Step 5: Bleed and Check

• Ensure no air bubbles remain in the brake lines.

• Press the brake pedal several times to verify firm, responsive feel.

Step 6: Final Cleanup

• Disconnect the hoses and turn off the power.

• Check the fluid level and wipe the area clean.
