Aside from the visual and acoustic warning signals a defective ABS or ESP system can be detected in exceptional situations when the wheels lock at full braking, or on handling in bends.

To the mid-90s ABS control units were usually placed inside the vehicle interior, which had a positive impact on their life. Today, they are usually located in the engine compartment near the hydraulic system and exposed to the prevailing temperature fluctuations and vibrations with their effect on the electronic components.

For all abs control devices listed on our website, we provide inspection and repair or overhaul, sometimes we also have replacement equipment or new equipment in stock.
