# 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 2.3.4: Free running test

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

In the case of tractors equipped with automatic brake adjustment devices, the brakes after completing the tests described in point 2.3.3 shall be allowed to cool to a temperature representative of a cold brake (i.e. ≤ 100 °C) and it shall be verified that the vehicle is capable of free running by fulfilling one of the following conditions:
2.3.4.1. Wheels are running freely (i.e. may be rotated by hand);
2.3.4.2. It is ascertained that when the vehicle is driven at a constant speed of v = 60 km/h or the maximum design speed of the towed vehicle, whichever is the lower, with the brakes released the asymptotic temperatures shall not exceed a drum/disc temperature increase of 80°C, then the residual brake moments are regarded as acceptable.
