This module prevents wheel lockup during braking, enhancing stability and control, and is typically found in commercial vehicles. Its design ensures precise brake force modulation, contributing to shorter stopping distances and improved vehicle handling in various conditions. This unit measures 137 x 40 x 126 mm and operates within a temperature range of -40°C to +75°C, while maintaining an IP 40 protection class. Its mounting utilizes 3x Ø 7.5 mm holes with a hole distance of 112x122 mm, and it is built to OE specification.

Key Features & Benefits

This little module is basically the brain behind your anti – lock brakes. It’s constantly monitoring the speed of each wheel using sensors. It calculates when a wheel is about to lock up during braking – that’s when it stops turning and you start to skid. When it detects that, it rapidly pulses the brakes on that wheel, allowing it to keep rotating and letting you maintain steering control. It also works with other systems, like traction control, if your vehicle has that. Basically, it’s taking information, making decisions, and controlling hydraulic pressure to keep you safe. It's a critical component of your braking system, obviously. Think of it as acting like a shield between you and losing control when you have to slam on the brakes, especially on slick surfaces like wet roads, snow, or gravel. It isn't replacing your normal brakes, it's working with them to give you the best possible stopping power and keep you steering. It’s usually located in the engine bay, near the brake master cylinder or hydraulic control unit.

Symptoms, Risks & Replacements

Honestly, it’s hugely important for safety. If this thing fails, your anti – lock brakes won’t work. You’ll notice if it goes bad – the ABS warning light on your dashboard will illuminate, and the system won’t engage when you brake hard. You can still stop the car with your regular brakes, but you lose that extra safety net that prevents wheel lockup and helps you steer. You can find these, and a lot of other parts, over at Fixparts Online if you’re looking to replace it yourself. It’s one of those things you really don't want to put off fixing if that light comes on.
