What are ABS Brakes and How do they work?

“Holy Guacamole my brakes locked up again last night and I was barely pressing on them!” If you drove a vehicle in the 70’s, 80’s, and 90’s this statement may have been true for you. Brakes have come a long way since then and your brakes locking up is no longer common. So, what are they and how do they work?

Early Anti-Lock-Brake Systems

Anti-Lock-Brakes were first invented by Frenchman Gabriel Voisin for use in aircraft to prevent tire slippage. They were installed on production vehicles starting in the early 70’s. The first system was called “Electronic Brake Force Distribution”. This system is still used today and is an important part of your braking system.

Modern Day Anti-Lock-Brake Systems

The modern day Anti-Lock Braking System is a computer controlled system that monitors the speed of each wheel. If it senses one or more wheels are about to lock up, it will automatically reduce the brake pressure to that wheel or wheels. This allows you to keep steering control of your vehicle and avoid skidding.

What are the components of the ABS system?

• Wheel Speed Sensors
• ABS Pump
• ECU

How Do ABS Brakes work?

When you press down on your brake pedal this creates pressure which is transferred through your brake booster to the master cylinder. The master cylinder then creates hydraulic pressure through brake fluid that runs through your brake lines to your brake caliper. The brake caliper then applies pressure the brake pads which in turn create friction on the brake rotor ultimately slowing down your vehicle.

ABS Brake systems work by monitoring the speed of your wheels via wheel sped sensors and if they sense one or more are about to lock up, the ABS pump automatically reduce the brake pressure. This allows you to keep steering control of your vehicle and avoid skidding.

Why are ABS Brakes Important?

ABS Brakes are important because they allow you to maintain control of your vehicle during an emergency braking situation. This can mean the difference between stopping in time or rear-ending the car in front of you.
