How do you bleed Toyota brakes with ABS?

Bleeding the brakes on a Toyota vehicle with an anti-lock braking system (ABS) requires a specific procedure to ensure the system functions properly. This process involves removing air bubbles from the brake fluid lines, which can affect the performance and responsiveness of the brakes.

Preparing to Bleed Toyota Brakes with ABS

Before you begin the bleeding process, make sure you have the following supplies on hand:

• Brake fluid that meets Toyota's specifications


• A clear plastic hose that fits the brake caliper bleed screws


• A wrench or socket to loosen the bleed screws


• A clean, lint-free rag


• A helper to assist with the bleeding process

It's also important to ensure that the brake fluid level in the master cylinder is at the proper level before starting the bleeding procedure.

Steps to Bleed Toyota Brakes with ABS

Follow these steps to bleed the brakes on a Toyota vehicle with an ABS system:

1. Locate the bleed screws on each brake caliper. These are typically located at the top of the caliper.


2. Attach the clear plastic hose to the bleed screw, and place the other end of the hose in a clean container to catch the old brake fluid.


3. Have your helper depress the brake pedal slowly and completely, then hold it down.


4. While the pedal is held down, open the bleed screw by turning it counterclockwise. Allow the fluid to flow through the hose and into the container.


5. Once the fluid flow slows to a trickle, close the bleed screw by turning it clockwise.


6. Repeat steps 3-5 until the fluid flowing through the hose is clear and free of air bubbles.


7. Move to the next brake caliper and repeat the process until all four wheels have been bled.


8. Once all the brakes have been bled, check the brake fluid level in the master cylinder and top it off if necessary.

Remember to bleed the brakes in a specific order, typically starting with the wheel farthest from the master cylinder and working your way towards the closest wheel. This helps ensure that all air bubbles are removed from the system.

Troubleshooting and Tips

If you encounter any issues during the bleeding process, such as a spongy or unresponsive brake pedal, double-check the following:

• Ensure the brake fluid level in the master cylinder is at the proper level


• Make sure the bleed screws are tightened completely after the bleeding process


• Verify that the brake fluid being used meets Toyota's specifications


• Consider having a professional technician inspect the braking system if the issues persist

Properly bleeding the brakes on a Toyota vehicle with an ABS system is essential for maintaining safe and reliable braking performance. By following the steps outlined above and using the right tools and materials, you can ensure your Toyota's brakes are in top condition.

Can you bleed ABS without a scan tool?

Yes, you can bleed ABS brakes without a scan tool, but it's more difficult and less thorough. You'll need to bleed the conventional brake system first, then activate the ABS pump by performing several hard stops on a loose surface like gravel to force the trapped air into the conventional lines. After activating the ABS, you will need to re-bleed the brakes again to remove any new air that has entered the system. 
Step 1: Perform a standard brake bleed 

• Bleed the brakes as you normally would, following the correct bleeding sequence for your vehicle (usually starting with the wheel furthest from the master cylinder). 
• Be careful not to let the master cylinder run dry, as this is a common way air enters the ABS system. 

Step 2: Activate the ABS 

• Drive the vehicle to a safe, loose surface like a dirt or gravel road. 
• Accelerate to a moderate speed and then slam on the brakes to activate the ABS. You'll feel the pedal pulsate and hear the system working. 
• You may need to do this several times to force all the air out of the ABS hydraulic unit. 

Step 3: Re-bleed the brakes 

• After activating the ABS, the brake pedal will likely feel soft, indicating air has been pushed into the conventional lines.
• Return to a safe location and repeat the standard brake bleeding procedure.
• Test the brakes again to ensure the pedal is firm and the air has been completely purged. 

Important considerations

• Some modern systems are more complex and may require a scan tool to properly flush the fluid from the ABS accumulator. 
• If the pedal remains soft after repeating this process, it's best to use a scan tool to perform a full ABS service, as recommended by the manufacturer. 
• If you're performing major brake work, such as replacing a caliper or master cylinder, the scan tool method is often recommended for a more thorough flush. 

Can I bleed brakes with ABS?

At Brakes-Shop.com, our experts know that tackling an ABS-equipped vehicle's brake system doesn't have to be intimidating. Years of hands-on experience and rigorous testing have shown that, for most vehicles, the process is straightforward and nearly identical to bleeding a non-ABS system.

Can air be trapped in an ABS module?

Some vehicles require a scan tool to activate the ABS pump. This tool circulates the fluid and dislodges air trapped within the ABS module.

What is the brake bleeding sequence for Toyota?

I just checked my factory service manual and Toyota says to do both rear wheels, then the front, then the bleeder on the frame. The best way I've found to bleed brakes is to have a friend pump the pedal up and hold it down while you crack a bleeder under the truck, and close it before your friend releases the pedal.
