刹车油，又叫制动液，是影响车辆刹车系统性能好坏的重要因素，在使用中，刹车油质量的好坏是备受关注的要素。那么，何为优质刹车油，它该具备哪些性能特点呢？
1、低温流动性很好，这对于严寒地区特别明显。使用优质制动液在严寒时制动一样灵敏、可靠。而使用劣质制动液温性能差，凝固点高，低于20℃气温就会有凝固现象发生，大大影响行车安全。
2、对刹车系统各种金属防锈性好。一般制动液腐蚀性较强，但优质制动液对各类金属防腐性防锈性大大减少，可延长刹车油泵寿命，若加了劣质制动液就会很快腐蚀金属，对行车造成危害。
3、对各种橡胶不腐蚀。优质制动液使用后极少发生皮碗严重膨胀变形现象。若使用劣质制动液，皮碗容易膨胀变形，导致车辆漏油、刹车时翻转，造成事故。标准制动液膨胀率一般在0.1%5%之内。5、长期使用无沉淀物。制动液长期在高温状态下使用，质量不稳定就会产生热分解，产生沉淀物，同样影响刹车性能。
4、沸点越高越好，较低蒸发性。沸点不低于205℃，当汽车长时间行驶、在高速或下坡行驶时，温度会高达数百度。制动液温度随着刹车蹄片温度升高而升高，若制动液沸点不够高，制动液汽化，产生气泡，踩刹车发软，不能立即达到刹车目的，就不能保证行车安全性。
