# 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 3.1.2: Secondary braking system

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

The secondary braking system, even if the control device which actuates it is also used for other braking functions, shall give a stopping distance not exceeding the following values and a mean fully developed deceleration not less than the following values:
Tractors with vmax ≤ 30 km/h:
0,15 v + (v2/39)
(the second term corresponds to a mean fully developed deceleration dm = 1,5 m/s2)
Tractors with vmax > 30 km/h:
0,15 v + (v2/57)
(the second term corresponds to a mean fully developed deceleration dm = 2,2 m/s2)
The prescribed performance shall be obtained by applying to the control device a force not exceeding 600 N on a foot or 400 N on a hand operated control device. The control device shall be so placed that it can be easily and quickly applied by the driver.
