Reasons to Bleed an ABS Brake

    • Anti-lock brake systems are a miracle of the modern age. They help stop a vehicle without locking up the wheels of the car when activated. This helps keep you in control of your vehicle during emergency situations. Yet an ABS needs to be maintained just like the rest of the car. Bleed the brakes from time to time to keep the system in full operational capacity. Bleeding removes excess air from the brake system.

    Spongy Brakes

    • When air is caught inside the lines of the brake system, this can lead to different issues. The brakes won't respond as well and feel spongy or soft. The air in the line has to be compressed before the hydraulic on the brake system can start to function. The brake will seem less firm and will take a moment or two longer to work.

    Uneven Brake Pressure

    • Air in the brake line can lead to uneven application of the brakes. This, in turn, can lead to wearing out the parts in the brake system much faster than intended. Brake pads that seem to wear out more on one side of the car than the other can be one sign the ABS lines need to be bled. Having uneven brake pressure can also lead to more force on one side of the car than the other. This can be an issue during an emergency, forcing the car into a situation where the driver loses control of the vehicle.

    Brake Failure

    • Not bleeding the breaks can also lead to break failure. The brake fluid inside the break lines needs to be replaced on a regular basis. If there is air in the brake lines, this means that older fluid that has been exposed to the elements is used instead of fresh brake fluid pumped through the anti-lock brake system. After several years of use, the brake fluid is often supersaturated with moisture, which can increase the risk of the fluid boiling out, and the loss of brakes under hard use. If the breaks are not properly bled and maintained, this can lead to a nonfunctional ABS when in an emergency.
