Wabco 4801030660 EBS Axle Modulator 2-Channel Gen1

Description

The Wabco EBS Axle Modulator 2-Channel Gen1 (MPN: 4801030660) is a critical component within the air brake system, specifically designed for drive axles in 4x2 vehicles. It functions as part of the Electronic Braking System (EBS) to regulate braking forces and enhance stability. This modulator features a robust design with IP 66 / IP 69 K protection, ensuring reliable performance in harsh environments. Its dimensions are 200 x 179 x 229 mm. The device operates at 24V with a rated current of 5A, and is built to OE specification. With integrated silencers and connections utilizing Bayonet DIN 72585 1A-4.1-Sn/K2, this modulator offers optimized airflow and secure connections, contributing to a safer and more efficient braking system.

Key Features & Benefits

This modulator basically controls the air brakes on an axle – specifically, it manages the air pressure going to the brake chambers on either side of that axle. It’s a two – channel unit, meaning it handles one brake on each side, independently. It receives signals from the ABS system, and uses those to quickly apply or release the brakes on that axle, helping prevent wheel lockup. It also balances the braking force left to right, so you get a smoother, more controlled stop. It's all about fine control of the air pressure. Think of it as a smart valve. It sits between the air reservoir and the brake chambers. It doesn't do the braking itself – the chambers do that – but it's the brain telling them how much to brake. It’s a key component of the entire anti – lock braking system. It takes information from the wheel speed sensors, then uses that to adjust the air pressure to each wheel. It’s a pretty crucial piece of the puzzle for modern air brakes.

Symptoms, Risks & Replacements

Well, without this working right, your ABS system can’t do its job. You’ll notice if this fails – usually it's a loss of ABS function, the ABS light comes on, and the vehicle won’t stop as effectively, especially in slippery conditions. It also prevents wheel lockup, which can lead to skidding and loss of control. It's a safety item, plain and simple. It protects you from losing control during hard braking, and helps keep you and others on the road safe.
