Brake fluids are classified by both “dry boiling point” and “wet boiling point.” They are also classified by US Department of Transportation (DOT) rating, DOT 3, DOT 4, DOT 5, and DOT 5.1.

Dot 5 and Dot 5.1好很多，但是注意換和加的時候一定要按照手冊

• 進空氣沒可能吧？最多多吸收些空氣中的水分而已，一人就幹又沒額外成本，挺好的！ -Oneshotkill- ♂ (0 bytes) () 09/16/2016 postreply 19:18:50

• 這樣個流法能流到猴年馬月？ -MoonRiverMe- ♂ (53 bytes) () 09/16/2016 postreply 20:41:16

• 此法可以保證不進空氣，隻需一人。缺點是慢。 -yanif- ♂ (0 bytes) () 09/17/2016 postreply 04:20:16
