Division 6.3.2 - 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)

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 (z_RALH and z_RALL), where

$\frac{z_{RALH}}{ε_{H}} \geq 0,5$ and $\frac{z_{RALH}}{z_{RALL}} \geq 2$

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 z_RALH/z_RALL may be ascertained by the procedure in point 2 of Appendix 2 or by calculating the ratio z_RALH/z_RALL. 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.
