好的 待會來給他好好的磨一磨
In our experience the most common cause of disc distortion is the failure of drivers to ‘season’ or stress-relieve new discs by following recommended bed-in procedures.
在我們的經驗之中,最常見到的情況就是駕駛者的習慣或者新碟盤的時候沒有做好磨合.
During the disc casting process molten iron is poured into sand moulds at temperatures in excess of 1350˚C and allowed to cool rapidly into solid form.
碟盤的製作過程中熔鐵以超過攝氏1350度被灌入沙模而且馬上就冷卻下來成為固體
This rapid cooling causes internal stresses to be ‘stored’ within the disc casting.
這樣的迅速冷卻過程中很多的內應力被儲存在碟盤裡面
Gradual and moderate thermal cycling (as experienced when bedding-in discs properly after fitment) is a very effective method of relieving these stresses.
適度的熱循環(安裝完碟盤之後的磨合)是很好釋放碟盤裡面的內應力最好的方法
On the other hand - sudden, dramatic heating and cooling of un-seasoned discs can lead to distortion or cracking.
換句話說~突然的,劇烈的呼冷呼熱將會導致失真或者龜裂
So, the message is clear. Always bed discs in correctly prior to hard driving.
所以事情很明顯了.在狂操之前請先磨合你的碟盤
This will relieve internal stresses within the disc and ensure maximum resistance to distortion.
這樣可以釋放碟盤的內應力且可以大大的避免碟盤失真
Powerbrake™ discs ALL undergo a series of ‘weathering’ processes during manufacture that are designed to stress relieve the disc castings.
雖然Powerbrake™的碟盤都有經過我們的專利'風化"處理過程去釋放內應力且加強他們對變型及
龜裂的抵抗力.
Extensive testing has shown that these processes substantially reduce the chances of distortion and cracking.
大量的測試顯示出這些過程實質上可以減低碟盤失真跟龜裂
Having said that, we are the first to point out that correct bed-in has numerous other advantages and MUST be completed before any hard driving is attempted.
還是那一句話,我們指出正確的磨合有太多的好處而且必須在狂操之前就要做到
