Inadequate braking function or poor brake boost
If the above defect is noticed, the cause may be a faulty ESC unit for the Electronic Stability Control. Faulty or sticking pistons prevent a controlled pressure buildup or reduction in pressure in the hydraulic braking system. As the vehicle manufacturer does not provide for repair of this hydraulic unit, the component must be replaced in its entirety.
