回复：首先你沒有工具﹐經驗。換起來也不貴﹐生命可貴啊。

appreciate your warning. The reason why i ask this question is becasue i've seen so many people here doing the front brakes change themselve. Basically there is potential risk whether you do the front or the rear, as long as you are not the so-called Pros. So according to your principles, we should not even do the front brake changes, which in fact have been safely performed by many people here.So i guess my question is: Are you suggesting that brakes changing are so inherently dangerous that it should never be performed by non-technician no matter front or rear, or that the "Drum brakes" are more dangerous so we should not do it? Thanx alot
