近日台中連著好幾天雨下不停
週五晚上下班趁熱車時,檢查一下燈系,發現煞車燈,發現按了不會亮
週末檢查了一下發現是煞車開關故障,分享一下維修的方法
網頁好讀版:https://3wa.tw/blog/blog.php?id=1977

首先在車上先確認煞車開關的線頭有沒有插好
確實都有插好按了還是不亮,把開關拆下
煞車開關,通常拉桿放開時,開關會被拉桿頂著壓住,壓住就會讓接點分離
而按下拉桿,煞車開關會被「放開」,這時開關裡的銅接點,反而會合上導通
讓煞車燈通電發光,很精巧的設計

首先確認煞車開關的按鈕,發現一按就沉進去,搖一搖又會掉出來
已故障,內部的金屬接點都合不上,無法導通

使用一字子延著邊線慢慢翹,每個方向都翹就可以分離

如果有打算 DIY 練習自行維修的同學,建議拆下總成時,可以多看二眼這個部分
以免等會裝不回去

將零件拆出來後,大概可以分這些,翹起來的銅片、小彈簧、本體、還有翹翹板

雨天煞車開關裡積水,都生銹了

本體的座上跟翹翹的銅片都各有一個小圓孔,用來勾彈簧
銅片翹起來的尖腳也有他的功能,等會要勾右上那個翹翹板
https://i.imgur.com/nLIEi6v.png
這次故障的主因就是小彈簧的其中一支勾腳銹斷了

不管是什麼樣的銹,在小銅刷面前都只是水彩筆的顏料
玩車的人必備小銅刷、小鋼刷,什麼除銹水、WD40都沒這種物理攻擊兇猛

小彈簧維修,拿一支美工刀,往最後一、二簧的地方切入,往右邊扳平壓實
很容易就可以作出新的勾子
小彈簧維修完成,可以開始組裝

裝回最下面的接點片

小彈簧勾好

然後銅片小彈簧再跟主體合勾,彈簧一定要勾在洞裡,別勾歪了
這個步驟不熟練會一直掉,建議勾好後,把彈簧的開口壓成封閉型
就不會掉了

型狀變成這樣,把銅片往後拉,讓翹壓的地上翹上來
凸出去也沒關係,就是希望他的腳可以往上翹高
https://i.imgur.com/EquVTL2.png
https://i.imgur.com/mBXSOpG.png
忘了說明翹翹版勾銅片的地方,所以又把彈簧拿下來說明
等會往上翹的腳,要跟翹翹板的腳對扣,然後主體往後拉
https://i.imgur.com/hZxFGQ4.png
手要這樣抓剛才組裝好的部分
二支銅腳尖尖的地上會翹上來,這時翹翹板的腳勾上去,整個往後扣
https://i.imgur.com/dqQppmy.png
https://i.imgur.com/y7z8QiX.png
https://i.imgur.com/LX0DZ2E.png
就會扣成這個樣子,銅片後面的接點,會凸出大概2~3mm
翹翹板前面會壓著銅片的腳,後面會扣在主體上

上視圖

主體裝回,到這個步驟可以按看看開關有沒有裝好
平時未按下時,接點是接上的(導通)
當開關按下後,接點會分離

蓋回後測試電阻,平常是導通的,7.8Ω
https://i.imgur.com/t7BAiZ8.png
當開關被按到後,是開路,無限大Ω

回到車子,把煞車開關接好線,裝回車上,鎖上螺絲
https://i.imgur.com/Y4jHjhV.png
平時未拉煞車時,煞車焊不亮
https://i.imgur.com/Y3RAzb5.png
按下煞車後,可以正常亮燈

維修完成
換煞車開關是不貴,一個大概50~80$
但如果拆開裡面的東西能修,不坊試看看
不用花錢也能修好,只是花的時間比換新的還貴 XD
