How To Bleed Abs Brakes Without A Scan Tool

Bleeding your brakes is an essential part of maintaining your car’s safety. However, many drivers don’t know how to do it safely and without damaging their car. In this blog post, we will teach you how to bleed your brakes without a scan tool. By following these steps, you will be able to keep your car safe and maintain its performance.

What is ABS?

ABS (Anti-lock Braking System) is a type of braking system found on many modern cars. When you press the brake pedal, the ABS system tries to momentarily make the rotors stop spinning. This allows the car to stay stationary if it starts to move forward. If you release the brake pedal before the car has stopped, the ABS will try to keep the car from moving.

How ABS Works

How ABS Works

If you’ve ever had to change your brake pads on a car, then you’re familiar with ABS (anti-lock braking system). ABS helps the brakes stop the car quickly by preventing it from skidding. To work properly, ABS needs two things: good braking performance and accurate sensors.

The brake pads wear down and need to be replaced over time. When the pads are worn down, they can no longer provide enough resistance to the rotors, which means the car will start to slide. The ABS system is designed to prevent this from happening by using sensors to detect when the car is starting to slide and doing something (usually pumping the brakes) to stop it before it gets too far.

If your car has ABS, it’s important to keep the brakes fluid level topped off. Over time, the fluid can become depleted and will no longer provide the necessary damping or braking force. When this happens, the brake pads may start to wear prematurely and eventually require replacement. To keep your ABS system in good working order, you’ll need to bleed the brakes occasionally.

To bleed a set of ABS brakes without a scan tool, follow these steps:

1) Park your car on a level surface and ensure that both wheels are firmly grounded.
2) Remove the wheel caps and unscrew both front brake calipers (see illustration below). Bleed the brake lines by spraying them with brake fluid until they are completely filled with liquid (see illustration below). Make sure to hold onto thebrake hoses while doing this! Reattach the wheel caps and tighten screws.

3) Repeat steps 2-4 for the rear brakes. Be sure to hold onto both brake hoses while bleeding!
4) Reconnect all ofthe vacuum hoses and check for leaks before driving away.


Bleeding ABS brakes without a scan tool can be a daunting task, but with the right tools and some patience, it can be done. Before getting started, make sure you have all of the necessary tools: an adjustable wrench, removal keys for the caliper bolts and pads, brake fluid and a funnel. Next, remove all of the components from the front axle (ABS sensor, master cylinder and reservoir), paying particular attention to the bracket that holds both sensors in place. Once everything is removed, use your adjustable wrench to unscrew both sensors from their bracket. If they are still attached by screws, use your removal keys to twist them loose before discarding them. Finally, use your brake fluid funnel to pour fluid into each bleeder screw on either side of the bracket before re-attaching it with new screws and pads. Wait until all bleeding has stopped before reinstalling everything else on the axle. There is no need to bleed the rear brakes as they operate independently from ABS systems.[/vc_column_text][/vc_row]
