This may result in a delayed braking response. To prevent this, the PSCB brake pads on the front axle of the affected vehicles must be replaced with copper- free brake pads. The brake pad retainer springs on the rear axle must also be replaced to prevent brake noises ("squealing") at low speeds. Please arrange for this measure to be carried out on the affected vehicles the next time the vehicles come into the workshop.
