Division 6.2.3.3 Successive brake tests are performed
United Kingdom
Then this formula is used:
zF = zHy+F – zHy + R
zF zHy zHy+F R
Mean fully developed deceleration of the friction braking system including rolling resistance
Mean fully developed deceleration related only to the braking effect of the hydrostatic braking system including rolling resistance
Mean fully developed deceleration of the combination hydrostatic braking system.
Rolling resistance = 0,02
