# Commission Delegated Regulation (EU) 2015/68 of 15 October 2014 supplementing Regulation (EU) No 167/2013 of the European Parliament and of the Council with regard to vehicle braking requirements for the approval of agricultural and forestry vehicles (Text with EEA relevance), Division 2.2.1.11

Extent: E+W+S+N.I.

In hydraulic braking systems:
2.2.1.11.1. The filling ports of the fluid reservoirs shall be readily accessible; in addition, the containers of reserve fluid shall be so made that the level of the reserve fluid can be easily checked without the containers having to be opened. Where this last condition is not fulfilled, the red warning signal specified in point 2.2.1.29.1.1 shall draw the driver's attention to any fall in the level of reserve fluid liable to cause a failure of the braking system.
In hydraulic braking systems, where the type of fluid used for hydraulic transmission is common with the fluid used in other appliances of the vehicle in a common tank, it is also permitted to detect the correct level of fluid with a device which needs the container to be opened.
2.2.1.11.2. A failure in the hydraulic transmission where the prescribed service braking performance cannot be obtained shall be signalled to the driver by a device comprising a warning signal, as specified in point 2.2.1.29.1.1. Alternatively, the lighting up of this device when the fluid in the reservoir is below a certain level specified by the manufacturer shall be permitted.
In hydraulic braking systems, where the type of fluid used for hydraulic transmission is common with the fluid used in other appliances of the vehicle in a common tank, detection of a pressure drop in the hydraulic transmission to a certain value as specified by the manufacturer is also permitted.
2.2.1.11.3. The type of fluid to be used in the hydraulic transmission of braking systems shall be identified by the symbol in accordance with Figure 1 or 2 of Standard ISO 9128:2006. The symbol shall be affixed within 100 mm of the filling ports of the fluid reservoirs, in accordance with the requirements laid down in Article 24 of Delegated Regulation (EU) 2015/208. Additional information may be provided by the manufacturers. This requirement only applies to vehicles having a separate filling port for the fluid of the braking system.
