补充资料：汽车制动液
汽车液压制动系统中传递制动压力的液态介质。对汽车制动液的性能要求是：粘温性好，凝固点低，低温流动性好；沸点高，高温下不产生气阻；使用过程中品质变化小，并不引起金属件和橡胶件的腐蚀和变质。
制动液有三种类型。①蓖麻油-醇型:用精制蓖麻油和乙醇按1:1配制而成。在寒冷地区,用蓖麻油34％、丙三醇（甘油）13％、乙醇53％配制成的制动液,在-35℃左右仍能保证正常制动，但沸点低，易产生气阻。②合成型：用醚、醇、酯等掺入润滑、抗氧化、防锈、抗橡胶溶胀等添加剂制成，使用性能良好，工作温度可高达150℃,但价格较高。③矿油型：用精制的轻柴油馏分加入稠化剂和其他添加剂制成，工作温度范围为－70℃至150℃。它的使用性能良好,但制动系统须配用耐矿油的橡胶件。中国的矿油型制动液分"7号"和"9号"两种，"7号"用于严寒地区,"9号"用于气温不低于-25℃的地区。各种制动液不可混存和混用，否则会出现分层而失去作用。
