How to Properly Use a Brake Flush Machine in Canada

Maintaining your vehicle’s braking system is critical for safety and performance. One of the most essential maintenance tasks is replacing old brake fluid with fresh fluid. A Brake Flush Machine simplifies this process, ensuring a complete fluid change while minimizing risk and contamination. This guide will explain how to properly use a brake flush machine in Canada, covering the types of machines, step-by-step procedures, and best practices for vehicle safety.

What is a Brake Flush Machine?

A brake fluid flush machine is a specialized tool designed to remove old brake fluid from a vehicle’s braking system and replace it with new fluid. Over time, brake fluid absorbs moisture, which can cause corrosion in brake lines and reduce braking efficiency. Using a fluid brake change machine ensures that the old, contaminated fluid is completely removed, helping maintain optimal brake performance.

There are several types of brake fluid machine available on the market. Some of the models offered by Kenvo include the BFS-110 Brake Flush Service, BFS-115 Brake Flush Service, and BFS-125 Brake Flush Service. Each model caters to different vehicle types and service needs.

Why Brake Fluid Replacement is Important

Brake fluid is hygroscopic, meaning it absorbs moisture from the air over time. Moisture in the brake system can lead to:

• Reduced braking efficiency: Wet brake fluid lowers the boiling point, potentially leading to brake fade.
• Corrosion: Moisture can corrode metal components in the brake system.
• System failure: Old or contaminated brake fluid can compromise the master cylinder, brake lines, and calipers.

A regular brake fluid change using a brake fluid exchange machine helps prevent these issues and ensures your vehicle remains safe to operate. Most vehicle manufacturers recommend changing brake fluid every 2–3 years, but using a brake flush machine allows for a more thorough replacement than manual bleeding methods.

Types of Brake Fluid Machines

Understanding the type of brake flush machine is crucial for selecting the right equipment. Here are the most common types:

1. Pressure-Based Brake Fluid Machines

Pressure-based machines use compressed air or a pump to push new brake fluid through the system. The old fluid is simultaneously pushed out of the master cylinder and collected in a waste container.

Advantages:

• Faster fluid exchange
• Reduces manual labor
• Provides a complete flush of the system

2. Vacuum-Based Brake Fluid Machines

Vacuum-based machines draw the old brake fluid out of the system while simultaneously introducing new fluid. These machines are often portable and suitable for smaller workshops.

Advantages:

• Precise control over fluid removal
• Less risk of over-pressurizing brake lines
• Ideal for passenger vehicles

3. Automated Dual-Tank Brake Fluid Machines

Advanced machines like the brake fluid flush machine feature two tanks—one for new fluid and one for waste. They automate the entire process, from draining old fluid to filling new fluid, making them suitable for high-volume workshops.

Advantages:

• Minimizes human error
• Ensures complete fluid exchange
• Reduces risk of contamination

Step-by-Step Guide to Using a Brake Flush Machine

Proper usage of a brake fluid exchange machine requires preparation, caution, and following recommended procedures. Here’s a step-by-step guide:

Step 1: Gather Equipment and Safety Gear

Before starting, ensure you have:

• The correct type of brake fluid for your vehicle
• Protective gloves and eyewear
• Rags or absorbent pads for spills
• The brake flush machine ready and properly calibrated

Step 2: Prepare the Vehicle

1. Park the vehicle on a level surface.
2. Engage the parking brake.
3. Remove the wheels if necessary to access bleeder valves.
4. Locate the master cylinder and ensure it is full of fresh brake fluid.

Step 3: Connect the Brake Flush Machine

1. Attach the hoses from the brake fluid machine to the master cylinder and wheel bleeders.
2. Ensure connections are secure to prevent leaks.
3. Set the machine to the correct mode (pressure or vacuum, depending on the model).

Step 4: Flush the Brake System

1. Activate the machine to begin the fluid exchange.
2. Monitor the fluid color exiting the system; old fluid is typically dark or murky.
3. Continue until the fluid from all brake lines is clean and free of contaminants.

Step 5: Top Up and Check Fluid Levels

1. Fill the master cylinder with fresh brake fluid to the recommended level.
2. Inspect all connections for leaks.
3. Pump the brake pedal gently to ensure proper pressure.

Step 6: Test Brakes

Before driving the vehicle:

1. Test the brake pedal for firmness.
2. Check for any warning lights on the dashboard.
3. Perform a slow test drive to confirm brakes are functioning correctly.

Tips for Safe and Effective Brake Fluid Exchange

Using a brake fluid flush machine requires care to prevent damage to the vehicle and ensure safety:

• Use the correct brake fluid: Check your vehicle manual for DOT 3, DOT 4, or DOT 5.1 specifications.
• Avoid air in the system: Air pockets reduce braking efficiency. Ensure the system is fully bled.
• Regular maintenance: Replace brake fluid every 2–3 years or as recommended.
• Handle brake fluid carefully: It is corrosive and can damage paint or rubber components.
• Keep a clean workspace: Contaminants can compromise the brake system.

Advantages of Using a Professional Brake Fluid Machine

Using a professional brake fluid machine over manual bleeding methods offers several benefits:

• Efficiency: Machines reduce labor time and provide faster fluid replacement.
• Accuracy: Ensures a complete flush of the brake system.
• Safety: Minimizes the risk of air pockets and contamination.
• Versatility: Can service various vehicle types and brake systems.

Kenvo provides a range of professional brake fluid flush machines including the BFS-110, BFS-115, and BFS-125, designed for reliability and high performance.

Common Mistakes to Avoid

Even with a fluid brake change machine, mistakes can occur:

• Overfilling the master cylinder
• Not bleeding each wheel properly
• Using incompatible brake fluid
• Skipping post-flush brake testing
• Ignoring manufacturer instructions

Avoiding these errors ensures the longevity of your braking system and maintains vehicle safety.
