Toyota Corolla ABS System Parts

An anti-lock braking system (ABS) comes standard in a Toyota Corolla. The system is designed to help the tires stay connected to the road when stopping on slippery roads. Having a good understanding of how everything works is helpful if you have to make repairs or replace any parts.

An ABS system needs sensors, valves, a pump, and a controller to function properly so you can properly stop your Toyota Corolla. Here is an overview of each part and what it does:

• Sensors - Tires grip the road through a process called traction, which can actually be measured. Sensors are used to measure how strong of a grip a tire has on the road. The more grip the tire has on the road, the better the Corolla can stop normally. However, when roads are slippery, the grip isn’t as strong and the tires can lock up. This can send you into a spin if you don’t release the pedal and slow down properly. The sensors detect when a tire loses its grip on the road, and it will send a signal to a controller to adjust how fast the tire is spinning in order to maintain as much traction with the road as possible.
• Valves - The valves control the amount of brake fluid reaching the calipers. This will allow the fluid to flow freely so that when you press on the pedal, you’ll stop like normal on clear driving days. The valves can also restrict the flow to the calipers if the sensors detect that the car’s traction is unstable due to inclement weather or difficult road conditions, and lastly, they can reduce the pressure in the calipers to keep the tires from locking up if the Corolla starts to slide on a slippery surface.
• Controller - The ABS system uses a computer to accept the signals from the sensors, understand them, and send messages to the valves to tell them what to do. This computer is called a “controller.” The controller can adjust the pulse of fluid to the brakes hundreds of times a second.
• Pump - If the valve lets out pressure, something is needed to build it back it up instantaneously to make sure you can stop your Corolla. A pump is used to restore pressure. The pump consists of an accumulator, electric motor, and distribution block. The brake line for each wheel runs from the distribution block to the caliper.

The pump, controller, and valves sit on top of the engine. Therefore, they are easy to reach. The sensors are located underneath the Corolla by the tires. These parts can be removed with a ratchet and socket set. Overall, the process is relatively straightforward.
