Reported risk: The fault affects the brake system in particular the brake calipers on the rear axle. Because of a faulty coating hydrogen gas (approximately 10 ml) could be created in the coating of the piston of the brake caliper. This will be completely outgassed during the first 2 months after the production process causing longer brake pedal travel. Under certain circumstances the relevant brake pressure cannot be build up in the rear brake circuit. As a result the brake force of the system may be reduced by up to 30%. The driver may feel a soft brake pedal and a reduction of the brake performance. In certain cases the rear brake circuit could fail leading to increased risk of an accident. Remedy: On the affected vehicles the brake system will be bled.
