Choosing the Right Brake Bleeder: A Guide to ARES Tools for Effective Brake Fluid Maintenance

Choosing the Right Brake Bleeder: A Guide to ARES Tools for Effective Brake Fluid Maintenance

Maintaining your vehicle’s brake system is critical for safety and efficiency. Over time, brake fluid deteriorates, leading to decreased performance and even potential damage to the brake system if neglected. A proper brake fluid bleed is essential maintenance that every technician performs, and is easy enough for car owners or DIYers to do as well. To get the job done quickly and without hassle, you need the right tools. In this post, we’ll discuss two of our highly-rated brake bleeders from ARES Tools — the ARES 70921 2L Manual Brake Fluid Pressure Bleeder and the ARES 70923 1L Vacuum Brake Fluid Bleeder — so you can make an informed decision about which one is right for your brake service needs.

Why Brake Bleeding and Fluid Flushing are Important

Before diving into the details of these tools, let’s quickly review why it’s important to maintain your brake system. Brake fluid is essential for transmitting the force you apply on the brake pedal to the braking components at each wheel. Over time, moisture can seep into the fluid, leading to corrosion inside the brake system, reduced braking efficiency, and even the possibility of brake failure. It’s recommended to flush your brake fluid every two years to keep your braking system working as it should. See your specific vehicle's manual for details regarding service frequency. 

During brake bleeding, the process of removing air from the brake lines is crucial after a brake fluid flush or when air has entered the system. Air in the brake lines can cause inconsistent braking performance and dangerous situations. Both of these bleeders help minimize air in the brake lines if performed properly. Please see our detailed Demo video for further process, tips and tricks to ensure a proper brake bleed service:

The ARES 70921 2L Manual Brake Fluid Pressure Bleeder

Key Features:

  • Capacity: 2L
  • One-Person Operation: Designed for easy, single-person use with a manual pump.
  • Built-in Pressure Gauge: Monitors pressure, ensuring optimal brake fluid transfer.
  • Corrosion-Resistant Reservoir: Durable and easy to clean.
  • Universal Compatibility: Adapter works with most master cylinder reservoirs (including those on Alfa Romeo, Audi, BMW, Jaguar, and more).
  • Ideal for Disc and Drum Brakes: Works on a wide range of vehicle types.
Manual Brake Fluid Pressure Bleeder

Benefits of the ARES 70921 2L Manual Brake Fluid Pressure Bleeder

One of the standout features of the ARES 70921 2L Manual Brake Fluid Pressure Bleeder is its simple, one-person operation. No need for a second person to pump the brake pedal; you can fill the system with fluid and pressurize the system on your own. The built-in pressure gauge ensures you're applying the right amount of pressure (we typically recommend about 10 PSI) during the bleed, which helps avoid any mishaps with over-pressurizing the brake system.

The 2-liter capacity is perfect for most vehicles and allows you to complete the job without needing to stop and refill the fluid, saving time and effort. Plus, the included adapter works with a wide range of master cylinder reservoirs, so whether you’re working on a classic car or a late-model vehicle, you’re covered.

This bleeder is ideal for those who prefer manual tools that don’t require an air compressor. It's especially effective if you’re looking to perform a quick fluid change and bleed on a disc or drum brake system in your garage.

Perfect For: Mechanics who want an easy, reliable option for maintaining their brake systems without needing complex or bulky equipment.

The ARES 70923 1L Vacuum Brake Fluid Bleeder

Key Features:

  • Capacity: 1L
  • Air-Powered Operation: Uses your standard air supply to create a vacuum, making the brake bleeding process fast and easy.
  • Working Pressure: 71-113 PSI with a maximum pressure of 113 PSI.
  • Transparent Hose: Allows you to see fluid and air movement during the process for better visibility and control.
  • Hanging Hook: Hook the bleeder onto the caliper for less strain on the bleed connection.
  • Designed for Disc or Drum Brake Systems: Perfect for a variety of vehicles.

Benefits of the ARES 70923 1L Vacuum Brake Fluid Bleeder

For those who prefer an air-powered solution, the ARES 70923 1L Vacuum Brake Fluid Bleeder is a great choice. It connects to your workshop’s air supply and creates a vacuum that helps extract fluid and air from the brake lines, which can speed up the process. This system also includes a transparent hose, giving you clear visibility of the fluid and air being drained, so you know exactly when the job is done.

The vacuum-operated design takes the manual labor out of brake bleeding, allowing you to focus on controlling the process. The 1-liter capacity is compact but more than adequate for smaller jobs or for cars that don’t require a massive amount of fluid.

One of the benefits of this tool is its ease of use. You hook it up, apply air, and lock in the trigger, letting the tool work its magic. It’s especially useful for getting the air out of the system after performing brake repairs or fluid flushes, as well as for quick maintenance tasks.

Perfect For: Mechanics who already have an air compressor and want a hands-free, efficient way to perform brake bleeding tasks. It’s also ideal for users who appreciate clear visibility during the fluid draining process.

Key Differences Between the ARES 70921 and ARES 70923 Brake Bleeders

1. Operation Type:

  • ARES 70921: Connects to the master cylinder. Manual pump operation. Ideal for those who want full control without needing an air compressor.
  • ARES 70923: Connects to the brake bleeder screw (at the wheel). Air-powered operation. Requires an air supply and offers hands-free use, making it faster for some tasks.

2. Capacity:

  • ARES 70921: 2L reservoir, larger capacity for larger or more complex systems, or limiting the need to refill as often.
  • ARES 70923: 1L reservoir, perfect for smaller jobs.

3. Use Case:

  • ARES 70921: Great for single-person operation on a wide variety of vehicles, offering manual control.
  • ARES 70923: Best for those who have an air compressor and prefer a more automated, vacuum-powered approach to brake bleeding.

Summary: Which Brake Bleeder Should You Choose?

Choosing between these two brake bleeders depends on your specific needs and preferences.

  • Go for the ARES 70921 2L Manual Brake Fluid Pressure Bleeder if:

    • You prefer a manual, hands-on approach.
    • You don’t have access to an air compressor or prefer to avoid using one.
    • You want a larger 2L reservoir.
    • You value easy-to-monitor pressure control with the built-in gauge.
  • Go for the ARES 70923 1L Vacuum Brake Fluid Bleeder if:

    • You have an air compressor and want faster, hands-free operation.
