# 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 6.3.2

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

The provisions of this point shall only apply to towed vehicles equipped with an anti-lock braking system of category A. When the right and left wheels are situated on surfaces which produce differing maximum braking rates (zRALH and zRALL), where
z RALH ε H ≥ 0,5 and z RALH z RALL ≥ 2
the directly controlled wheels shall not lock when the force is suddenly applied on the control device of the tractor at a speed of 50 km/h. The ratio zRALH/zRALL may be ascertained by the procedure in point 2 of Appendix 2 or by calculating the ratio zRALH/zRALL. Under this condition, the unladen vehicle shall satisfy the prescribed braking rate in Appendix 3.
In the case of towed vehicle equipped with a brake load sensing device, the pressure setting of the device may be increased to ensure full cycling.
