Bosch ABS Pumps & modules

Bosch ABS pump repair


From the very beginning of ABS (Anti-lock Braking System) technology Bosch have been market leaders in concept and design for production vehicles, starting with the Mercedes-Benz W116.

However due to mass production, quality control problems arise. With each generation of Bosch ABS pump and module comes its own inherent fault.

We cover the entire range of Bosch ABS pump and modules and have been repairing these for many years. Using our bespoke Hardware-In-the-Loop test rigs allows us to test these ABS pump and modules under real-world load and driving conditions. Using only the highest rated components during rebuild we can ensure that each rebuilt Bosch ABS will exceed manufacture specification.
