Abs Brake System Sensor

Abs relies on a properly operating conventional brake system.

Abs brake system sensor.

There are many things that can cause your anti lock brake abs light to come on. Of course knowing the mechanism of abs sensor should also be considered. Based on the type of the braking system cars might have as few as one or even up to 4 abs sensors. Some of those things are serious but oftentimes it just means you need to clean the sensors.

Sometimes the abs light will come on because of a short or problem in the car s computer that has little or nothing to do with the brake system at all. Precision parts for abs technology. Anti lock braking abs systems allow the driver to maintain control of the car in an emergency braking situation. However the wheel speed sensor can easily get damaged due to the heat emitted by the brakes.

However abs brakes work under a system where abs sensors send information to the car s computer and the computer makes the decision to activate the abs function. One or more dirty wheel sensors all cars with anti lock brakes have at least one can cause the system to trigger the abs light during the computer s self evaluation cycle. The abs sensor is also called the wheel speed sensor or abs brake sensor. Abs is an automated system that uses the.

High tech sensors oe quality. Usually the brake fluid level sensor and the parking brake are the only two items that can activate the brake light. But not all vehicles are the same and some of the earliest abs systems would trigger both lights simultaneously for any. An anti lock brake sensor or abs sensor is a type of tachometer that measures the rotational speed of a wheel and passes it to the car s engine control module ecm.

The tone ring and the magnetic sensor. Abs wheel speed sensor by holstein. On the other hand for the newer systems abs sensors are fitted in the wheel hub assembly itself. An abs anti lock braking system is an enhanced braking system which is commonly found in newer automobiles.

Abs operates by preventing the wheels from locking up during braking thereby maintaining tractive contact with the road surface and allowing the driver to maintain more control over the vehicle. An anti lock braking system abs is a safety anti skid braking system used on aircraft and on land vehicles such as cars motorcycles trucks and buses. If the rest of your braking system is in working order you should usually still have normal braking without abs. Should the abs detect that one of the wheels is moving slower than the rest the system increases the pressure of the brake fluid.

This is meant to allow the wheel to move in sync with the others. The brake light on most vehicles is activated by a simple circuit involving only one or two components.
