Lub ntsiab zoo:
(1) Compact qauv, txhim kho braking efficiency
(2) Kev tswj tau yooj yim thiab txhim khu kev qha, thiab lub suab nrov ntawm braking yog txo qis
(3) Tsis tas yuav tsum muaj lub tshuab nqus tsev vacuum, uas txo qhov kev ncaws pob ntawm tus nres pedal thiab muab kev xav zoo dua;
(4) Vim tias qhov kev txhim kho ntawm qib ntawm kev hloov pauv, qhov hloov pauv ntawm tus qauv tsim tau zoo dua qub hauv cov txheej txheem tsim tsheb, cov naj npawb ntawm cov nres nres tau txo, thiab qhov kev teeb tsa ntawm lub nres nres hauv lub tsheb tau txais kev cawmdim.
