The pressure, at which ABS cycling commences, shall be determined by making five tests from 100 ± 2 km/h in which the brake pedal is applied up to the level which produces ABS operation and the five pressures at which this occurs as determined from front wheel pressure records, shall be recorded and the mean value obtained as pabs.
Rõhk, mille juures mitteblokeeruv pidurisüsteem käivitub, määratakse kindlaks viie katse tegemisega kiirusel 100 ± 2 km/h, mille ajal piduripedaali vajutatakse kuni mitteblokeeruva pidurisüsteemi käivitumiseni, ning viis rõhunäitajat, mille juures see esiratta rõhumeerikule tuginedes toimub, registreeritakse ja saadakse keskväärtus Pabs.
