"Disc brake rotors usually last so long that many people treat them as 'fit and forget' components. However, manufacturers provide minimum thicknesses for their rotors. Shimano recommends that its rotors, which start out 1.8mm thick, should be replaced when the braking surface has been reduced to 1.5mm." ...... "Brake rotor thickness is a crucial measurement for your vehicle's safety. It is important to know your vehicle's minimum brake rotor thickness because if the rotor is thinner than the minimum thickness, it can be dangerous to operate. Thinner rotors are lighter in weight and less able to absorb and dissipate heat." Brake rotor thickness is a crucial measurement for your vehicle's safety.

内侧刹车盘和刹车片都磨损出沟痕。外侧却很平整。 什么原因？
难道是因为内侧更靠近caliper？
第一张是外侧，第二张是内侧的
不然换了新的刹车皮，还会发生同样的问题。

Rotor得换，caliper guiding pin or cylinder 都可能绣死了不能回位。
刚刚换了新的rotor 和 pad。同时发现一个caliper上piston 的橡胶密封圈烂了。又换了个caliper。
目前感觉良好。
上下班加买菜。
她嘛，轱辘飞掉也许都不会知道。
LD 开着顺手一直不肯换。好在没什么毛病，也没有太多复杂的电子控制。常规维护我都可以自己做了。
本想该换一辆，结果现在买车利息如此之高，于是下决心耐心等待下一次经济危机到来再换车。
估计明年上半年也许就有机会看见车商大甩卖了。
