1.5升三缸EcoBoost渦輪增壓直噴引擎提供車重1360KG的FOCUS MK4 ST LINE,182匹最大馬力與240N-m最大扭力。而原廠煞車系統程序設定是很直接沒錯,但會為麼重踩個幾下就軟了…

FOCUS MK4 ST LINE is having 182 horse power and 240N-m maximum engine torque from OEM system setting. About the brakes setting, yes it’s working directly but it’s very easily faded at brakes performance.

JBT為此提供SP4P 355mm浮動碟套件,補足原廠制動效能的不足,如熱衰竭容易、踏板行程過深、煞車力度難以輕易掌控、極降速過慢等等因素做提升。

JBT brakes offer the kit “SP4P 355mm AF rotor kit" for FORD FOCUS MK4 ST LINE.

SP4P提供更加縝密線性的輸出供油,補足前段的虛,使煞車踏板不再是從四分之一深後才開始有煞車的感覺,正常市區使用踏板明顯開度高了許多,正常使用乘客也不會因偌大的煞車力而感受到壓迫感,而極降速方面,危急狀況時,給予適當且舒適的安全感。

The calipers (SP4P) provide you more smoothly performance in normally using. It’s no longer necessary to push deeper just for get a few brakes. In emergency, brakes will work accurately. Even your passengers won’t feel any uncomfortable when they face the huge brake power.

JBT 355mm浮動碟尺寸規格為直徑355mm,碟盤厚度32mm,提供更有效的散熱性以及卡鉗輸出加大的同時碟盤承受結構也因應強化數倍,使踩踏回饋感是紮實有信心。

About JBT 355mm rotor, the thickness of rotor is 32mm, It makes more stronger at construction especially when your calipers have already updated higher power.    

 

則原廠規格原為直徑282mm,厚度27mm。
