for any increased movement of its components arising from wear. Such devices shall themselves contain provision for securing them throughout their working range in any position in which they may be adjusted to or to which they may themselves automatically adjust.
35.2.2.                          'Parking Brake System 35/00'
35.2.2.1.                    The vehicle shall be equipped with a 'Parking Brake System 35/00' such that in the applied position retention is effected by mechanical means, and the braking effect is achieved by either:
35.2.2.1.1.              the frictional force developed between 2 friction surfaces; or
35.2.2.1.2.              the frictional force developed between two friction surfaces, together with a 'Parking Mechanism 35/00' as defined in clause 35.1.17.
35.2.2.2.                    The parking brake 'Control' shall be separate from the service brake 'Control' and incorporate a device to retain it in the "brake on" position, and it shall be designed to minimise the possibility of inadvertent release of the brake. This requirement shall be deemed to be satisfied if at least 2 separate and distinct movements are necessary to disengage the               parking brake.

35.2.2.3.                    Parking Brake Indicator Lamp
35.2.2.3.1.              The vehicle, if not fitted with a 'Spring Brake System' or 'Lock Actuators', shall be provided with a lamp which indicates that the parking brake is engaged. At the option of the 'Manufacturer' the lamp may be common with or distinct and separate from any service brake failure 'Visible Indicator' lamp. In the case of a common lamp, the lamp shall be labelled with the word "BRAKE"; or the symbol for "BRAKE FAILURE" - specified as Number 4.31 in the ISO document referred to in clause 35.2.1.2.5. In the case of a distinct and separate lamp the lamp shall be labelled with at least the words "PARK BRAKE" or "PARKING BRAKE"; or the symbol for "PARKING BRAKE" specified as Number 4.32 in the ISO document referred to in clause 35.2.1.2.5 placed either directly on the lens or adjacent to it in such a way that the label is illuminated by the same light source as the lens. The letters of the label shall be not less than 3 mm high and shall be of contrasting colour to their background when illuminated. If the label is directly on the lens the colour of either label or lens shall be red and if the label is not on the lens the colour of the lens shall be red.
35.2.2.3.2.              The parking brake indicator lamp and its specified label shall be located within the space boundaries specified in clause 35.2.1.2.6.
35.2.2.4.                    The 'Parking Brake System 35/00' shall incorporate devices which compensate for any increased movement of its components arising from wear. Such devices shall themselves contain provision for securing them throughout their working range in any
