5. Requirements U.K.

5.1. General U.K.

5.1.1. The drive control device shall be constructed in such a way that accidental reversing is prevented during a journey on the road. U.K.

5.1.2. To facilitate vehicle recovery, a device is required disengaging the connection between engine and drive wheels. U.K.

It shall be impossible to operate this device from the driving position during the journey on the road.

If a tool is needed to operate this device, it shall be carried on the vehicle.

5.2. Design requirements for the braking systems. U.K.

5.2.1. Service braking system U.K.

5.2.1.1. It shall be possible to apply graduated braking action of the service braking system. The driver shall be able to achieve this braking action from his driving seat and retain control of the steering device on the tractor with at least one hand. U.K.

5.2.1.2. The performance of the service braking system required under the Regulation shall be obtained by the actuation of a single control device. U.K.

5.2.1.2.1. This requirement is also deemed to be satisfied when the foot is moved from the drive pedal to the brake pedal or when at the start of the braking sequence, the drive control device is released or moved to neutral position by hand or foot. U.K.

5.2.1.2.2. The control device of the service braking system shall be designed to return to the initial position automatically when released. U.K.

This does not apply to the hydrostatic section of the braking system when the release of the hydrostatic drive control device creates the braking effect.

5.2.1.3. Contrary to point 5.2.1.1, with vehicles of Class I and Class II, when braking with the service brake system another brake system may also be used (secondary or parking braking system) to bring the vehicle to a stop on a gradient in the event of a residual creep speed. U.K.

5.2.2. Secondary braking system U.K.

5.2.2.1. With regard to the secondary braking system the relevant requirements of point 2.1.2.2 of Annex I shall be fulfilled. U.K.

Textual Amendments

F1 Deleted by Commission Delegated Regulation (EU) 2016/1788 of 14 July 2016 amending Regulation (EU) No 167/2013 of the European Parliament and of the Council as regards the list of requirements for vehicle EU type-approval, and amending and correcting Commission Delegated Regulations (EU) No 1322/2014, (EU) 2015/96, (EU) 2015/68 and (EU) 2015/208 with regard to vehicle construction and general requirements, to environmental and propulsion unit performance requirements, to vehicle braking requirements and to vehicle functional safety requirements (Text with EEA relevance).

5.2.3. Parking braking system U.K.

With regard to the parking braking system the requirements of point 2.1.2.3 of Annex I shall be fulfilled.

[F2 5.2.3.1. If, in the case of a hydrostatic drive, the vehicle cannot be stopped on a gradient, then it is permissible to operate the parking braking system to stop the vehicle from residual creep speed to standstill. For this purpose the parking braking system has to be designed such that it is possible for it to be actuated during driving.] U.K.

Textual Amendments

F2 Inserted by Commission Delegated Regulation (EU) 2016/1788 of 14 July 2016 amending Regulation (EU) No 167/2013 of the European Parliament and of the Council as regards the list of requirements for vehicle EU type-approval, and amending and correcting Commission Delegated Regulations (EU) No 1322/2014, (EU) 2015/96, (EU) 2015/68 and (EU) 2015/208 with regard to vehicle construction and general requirements, to environmental and propulsion unit performance requirements, to vehicle braking requirements and to vehicle functional safety requirements (Text with EEA relevance).

5.3. Characteristics of the braking systems U.K.

5.3.1. The set of braking systems with which a vehicle is equipped shall satisfy the requirements laid down for service, secondary and parking braking systems. U.K.

5.3.2. In the event of breakage of any component other than the brakes or the components referred to in point 2.2.1.2.7 of Annex I, or of any other failure of the service braking system the secondary braking system or that part of the service braking system which is not affected by the failure, shall be able to bring the vehicle to a halt in the conditions prescribed for secondary braking, in particular, when the secondary braking system and the service braking system have a common control device and a common transmission; for example, when the braking effect is dependent on the operation of the proper operation of the power transmission i.e. converter, hydraulic pumps, pressure pipes, hydraulic motors or comparable components. U.K.

5.3.3. The systems providing service, secondary and parking braking may have common components as long as they fulfil the conditions as specified in point 2.2.1.2 of Annex I. U.K.

[F3 5.3.4. The braking force distribution of the service brake system shall be designed in such a way that during braking there is no significant moment around the vertical axis of the vehicle if the limit of adhesion between tyres and road on homogeneous road surfaces is not attained.] U.K.

Textual Amendments

F3 Substituted by Commission Delegated Regulation (EU) 2016/1788 of 14 July 2016 amending Regulation (EU) No 167/2013 of the European Parliament and of the Council as regards the list of requirements for vehicle EU type-approval, and amending and correcting Commission Delegated Regulations (EU) No 1322/2014, (EU) 2015/96, (EU) 2015/68 and (EU) 2015/208 with regard to vehicle construction and general requirements, to environmental and propulsion unit performance requirements, to vehicle braking requirements and to vehicle functional safety requirements (Text with EEA relevance).

5.3.5. The braking force distribution of the service braking system shall be by design such that during braking with the service brake system on surfaces with different coefficients of friction of split-μ 0,2/0,8 a minimum deceleration can be achieved that is at least 55 % of the mean fully deceleration dm of the service braking system prescribed for the respective vehicle class (see point 6.3). This can be proven by calculations; in this case the rolling resistance shall not be taken into consideration. U.K.

5.3.6. By way of derogation from point 5.3.2, in the event of a failure in the pump control device of the hydrostatic drive, it shall be possible to stop the vehicle with the performance prescribed for the secondary braking system. However, under this failure condition an additional device may be actuated that can always be easily operated from the driving position (for example a device acting on the engine speed, including the engine shut off control). U.K.

5.3.7. In the case of an inch device, or other comparable device, which can be operated during driving, provisions shall be taken to ensure that all prescribed requirements of this Annex (especially the braking performance) are still complied with when this type of device is actuated. U.K.

5.3.8. Warning signals and warning devices U.K.

The relevant requirements of point 2.2.1.29 and point 2.2.1.12 of Annex I shall be fulfilled.

5.3.9. The energy storage devices (energy reservoirs) of power-driven vehicles shall be such that after eight full-stroke actuations of the service braking system control device the pressure remaining in the energy storage device(s) shall be not less than the pressure required to obtain the specified secondary braking performance. U.K.

5.3.10. The pneumatic/hydraulic auxiliary equipment shall be supplied with energy in such a way that during its operation, the prescribed deceleration values can be reached and that even in the event of damage to the source of energy the operation of the auxiliary equipment cannot cause the reserves of energy feeding the braking systems to fall below the level indicated in point 2.2.1.12 of Annex I. U.K.

5.3.11. Wear of the brakes U.K.

The relevant requirements of point 2.2.1.10 of Annex I shall be fulfilled.
