1, bonum ex tympanum freni function, because the brake to make out, combined with the rotation of the wheels of the brake drum of the distortion of a perspective (of course, but not big enough to let you easily can see) brake to land tension (dynamic braking system), the greater the situation becomes more obvious, therefore, generally large vehicles or use drum brake, in addition to low cost, big cars and small cars of drum brake, the difference may only have large mining pneumatic auxiliary, and small mining vacuum auxiliary brake to help.
2, sumptus humilis: technologia fabricationis frenorum tympani humilis est, sed etiam prima in systemate frenorum adhibita, ergo sumptus fabricationis minor est quam frenorum discoidum.
3, mechanismi freni manualis installatio facilis est. Nonnulla exempla rotae posterioris cum freno disco, in centro mechanismi freni manualis cum freno tympano et disco freni collocabuntur.
Progressus inclinatio
Propter celeritatem vehiculi et celeritatem currus celeriter crescentem, ut stabilitas freni augeatur cum vehiculum magna celeritate currit, frenum discoidum in systemate freni hodierno praecipuum factum est. Quia discus freni aeri expositus est, frenum discoidum optimam dissipationem caloris habet. Cum vehiculum subito magna celeritate frenat vel brevi tempore pluries frenat, efficacia freni non facile minuitur, ita ut vehiculum meliorem effectum frenandi consequatur et securitas vehiculi augeatur. Et propter celerem responsionem freni discoidi et facultatem actionis frenandi altae frequentiae, multa exempla curruum frenum discoidum et systemata ABS, VSC, TCS, aliaque systemata utuntur, ut necessitatibus talium systematum celeriter frenandi satisfaciant.
