BMW 34521182077 ABS SENSOR

Description

The ABS SENSOR is a critical component responsible for monitoring the speed of the rear wheels in BMW vehicles, specifically designed for the 740 and 750 models. It is typically installed on both the left and right rear positions. By providing accurate speed information, this sensor enables the Anti-lock Braking System (ABS) to function effectively, thereby enhancing vehicle safety and stability.

Key Features & Benefits

These little guys basically monitor how fast each wheel is spinning. They send that information to the car’s computer – the ABS module. It’s a magnetic sensor, so it doesn’t have any moving parts to wear out quickly. It just reads changes as the wheel’s tone ring – a toothed ring – passes by it. The ABS sensor is a key part of your anti – lock braking system. That system prevents your wheels from locking up when you brake hard, letting you steer while slowing down. It also feeds information to things like your traction control and stability control systems. So it’s not just about braking, it affects how well you maintain control of the vehicle overall.

Symptoms, Risks & Replacements

Without a working ABS sensor, your ABS light will come on, and the system won’t be able to function properly. You’ll notice if one goes bad because the light will be illuminated on your dash, and potentially, during hard braking, you might feel pulsing in the brake pedal or a loss of braking assistance. It’s a safety thing, honestly. A failing sensor can make it harder to stop safely, especially in slippery conditions. You can find these pretty easily, places like Fixparts Online carry a good selection, but getting the right one for your specific vehicle is important. They’re usually pretty straightforward to replace, but if you're not comfortable doing it yourself, it’s best to have a mechanic take a look. Product information is provided for reference only.
