地址用雞排..............
廣告品....
粗看還可以........
拆開包裝一看.....
原來是粗糙的可以.............
還有落漆(應該算包裝後兩片相互磨損的結果)!@@....這也能出貨?......肯定沒有ISO認證....*還是台灣先進國家就是這麼搞?..算正常的???..我少見多怪......等一下有人又要說...管它包裝外觀..."好用就好..利就是利!!...讚喔!"....(好.......等我裝好試試再說)......
再仔細看內容....跟原廠的一比....厚度是一樣...但是"肉"小了許多......也就是接觸面積少了...這還能稱"利"嗎?...那就厲害嚕!......
等我有空裝上試試就知...........
原廠的接觸面積比雞排大.......也就是斜切線的肉應該是滿的...
上圖看得出是"事後"(成形後)噴漆..流下痕跡.....質感粗糙.......

今天抽空把雞排裝上了....(10610km)
拆下來看....
上次換上的原廠的來令片才用五千公里左右....如果不那麼早換..估計應該比第一次撐更久(六千km吧?..新車第一次換的約在5700km..)......因為其實肉厚還有一半..但是有一邊兩端磨得不平均....所以我才以為快磨光!?@@.......
"雙耳"這一邊只吃大約一半而且受力平均(最厚約有2mm).....不過活塞加壓"單耳"這一邊則是吃偏...最薄的地方只剩1mm.....浮動式碟煞的宿命?....也就是活塞加壓這一邊的壓力較大..而且兩頭受力不均(一邊剩2mm..一邊剩1mm..)..
下圖...可看出單耳比雙耳不平均...雙耳的兩端一樣剩2mm...
下圖可看出比較第一次換的和第二次換的偏吃形狀一樣(都吃單邊而且是下方吃較多)....可見這棵碟煞有怪癖..不曉得算不算正常?..總不能老怪浮動式就是這樣....只好繼續觀察.....
我這次換來令片還把固定用來令片的軸做清洗..看是不是比較滑順?....
裝上去也不見得多好看........順便清洗一下卡鉗本體(沒那麼多精神..所以只是重點式清理...)...用的是過期WD-40........希望沒噴到碟盤?!@@........
初步測試後...........
大失所望...剛跑幾公里之後覺得一點都不利!...有上當的感覺.........
煞車力簡直跟後輪的鼓煞差不多.....
不過...我再試久一點看看....再下結論.....

1990年代以後石棉材煞車來令片因會致癌...所以都不再採用了...
煞車來令片(Brake pad)依成形基本上有兩種....
一種是樹脂Resin Mold式(Organic有機?)........
一種是燒結式Sintered...
*還有一種是半陶瓷半碳素....磨擦係數更好..比起燒結的工作溫度低更具持久性..振動也小....
樹脂Resin Mold式成份中骨格材料有代替石棉的鈦酸鉀..金屬纖維等.........潤滑材料有Koks焦炭..石墨(黑鉛)..金屬硫化物等...研削材...Dumping材(橡膠類)..PH調整劑(鹼性如消石灰等).....再以樹脂(苯酚)來燒固定形...因為是樹脂..所以高溫會分解衰退....用在輕形車輛或二輪車.......
燒結式成份為金屬(銅..鋁合金等)..研削材...潤滑材等以高溫高壓燒結而成......安定..耐磨..所以用途較酷...
據說以前的碟盤是鑄鐵...所以來令片用軟材質配方(如石棉)...但是現在用不鏽鋼碟盤..則可搭配更硬有機及金屬材質...不然鑄鐵狠快就被"咬"掉.....
一般車多用有機片....賽車多用燒結片(也有賽車級的有機片)...
聽說有機片的皮磨得快但比較不磨碟盤....要是用燒結片則相反..碟盤磨損快...但耐高溫及耐濕性比較好..

Ceramic Types
Semi-metallic (aka semi-met) brake pads contain iron, copper or other metal powders to prevent the pad material from melting and to increase braking power, but they are louder than other pads and are abrasive to the rotor. Non-asbestos organics (NAO) pads utilize kevlar, aramid or fiberglass fibers to increase longevity, but they offer less braking power and don't perform well at high temperatures.
Sintered Metal Pads
Sintered metal pads are made by pressing metal dust together under high temperatures and pressures. These metals, which generally include copper and/or iron as main elements and tin or zinc as alloying elements, essentially melt to the rotor on application. Sintered pads offer unmatched braking power, but only work well at high temperatures and require hardened stainless steel rotors that won't disintegrate under the metal pads.
Applications
Sintered metal pads offer little to no progressivity, meaning that application is either on or off like a light switch. Combined with their other drawbacks, this makes the sintered metal pad far less useful for everyday street use than an organic. If you want a high performance pad for the street, go with a specialized semi-met organic.
地址原廠及雞排好像看到銅的成份...看起來有燒結品的味兒?...不過應該不是.....因為沒人告訴我..所以我也不敢斷言...哈...
看看兩例燒結品......
