Wabco 4801041060 EBS Axle Modulator 2-Channel Gen2

Description

The Wabco EBS Axle Modulator 2-Channel Gen2 (MPN: 4801041060) is a critical component within a vehicle's air brake system, specifically functioning as an air processing unit. It is designed for drive axles with a 2S 2M 4W configuration and plays a vital role in modulating axle braking forces for enhanced stability and control. This modulator features robust construction with an IP 6K6K / IP 6K9K protection class, ensuring reliable performance in harsh operating environments. Operating at 24V with a rated current of 10A and a maximum operating pressure of 12.8 bar, the device maintains consistent performance across a wide temperature range of -40°C to +80°C. Its dimensions are 139 x 154 x 222 mm, and it is manufactured in Germany to OE specification.

Key Features & Benefits

This thing basically controls the air pressure to each axle's brakes independently. It takes the signal from your ABS system and uses it to rapidly apply or release air to the brake chambers at each wheel. That allows for precise control, especially during hard braking or when one wheel starts to lock up. This version is a 2 – channel, meaning it handles the front and rear axles as separate braking systems, giving you finer control than an older single – channel unit. It's all about regulating the airflow. Think of it as the brains behind your anti – lock braking system when it comes to actually doing the braking. Your ABS computer detects wheel speed, and this modulator is what translates that information into action at the wheels. It’s part of the air processing unit, sitting between the air compressor and the brake chambers. It receives signals, manages airflow, and delivers precisely metered air pressure. It’s a key part of making sure your trailer – or truck – stops safely and predictably.

Symptoms, Risks & Replacements

Well, without this working correctly, your ABS system can’t do its job. That means you lose the ability to prevent wheel lockup, and that dramatically increases your stopping distance, especially in slippery conditions. You'll notice if this fails, usually through an ABS warning light, and potentially by feeling the brakes lock up. It really is a critical safety component. We carry these at Fixparts Online, and a lot of our customers swap these out when they’re diagnosing ABS problems. Getting a good one is really important – it’s not something to cheap out on.
