Perodua Bezza — Brake Fluid Moisture Too High, Full Replacement (Wangsa Permai)

Bezza owner from Wangsa Permai noticed soft brake pedal. Moisture test: 3.5% — above safe limit. All four calipers bled, fresh DOT 3 filled. Pedal feel firm again.

Perodua Bezza — Brake Fluid Moisture Too High, Full Replacement (Wangsa Permai)

Wangsa Permai 的 Perodua Bezza 1.3 车主,行驶约 4 万公里,反映刹车踩下去感觉比以前软,尤其是连续多次刹车后更明显。

检查发现

刹车液沸点测试:水分含量 3.5%(超过建议更换标准 3%)。

刹车液已吸收过多水分,沸点下降,连续刹车时气化风险上升(刹车衰退)。

刹车片厚度正常(前 6mm,后 5mm)。

刹车卡钳无泄漏。

处理项目

全车排放旧刹车液

注入新 DOT 3 刹车液(Perodua 原厂规格)

四轮刹车卡钳放气(Bleeding)

刹车踏板手感测试

完成结果

更换后刹车踏板手感明显变硬,制动响应更直接。建议每两年更换一次刹车液,这是大多数车主容易忽略却很重要的保养项目。
