Fluid leakage from the ABS pump is a rare but extremely dangerous failure of the braking system. The leakage problem most often concerns popular controllers, such as Bosch pumps (models 5.3, 5.4, 5.7) and ATE MK70. The main symptom that should worry you is the brake pedal sinking to the floor. Ignoring this signal may lead to a tragic accident.
Why does ABS hydraulics leak?
The most common cause of problems with leaking ABS hydraulics is maintenance negligence, and specifically the lack of regular replacement of brake fluid. This liquid is hygroscopic, which means that it absorbs moisture from the environment over time.
Even a few percent water content in the liquid starts the corrosion process inside the hydraulic block. It is rust that damages the seals and causes fluid leakage from the ABS pump. That is why prevention and periodic fluid replacement are so important, which allows water to be removed from the system.
Professional repair of the ABS pump — what to do when it's too late?
When leaking ABS hydraulics are a fact, replacing the fluid alone will not solve the leak problem. In this case, specialized intervention is necessary.
