沃尔沃S40刹车片更换在您的家庭或办公室。

When to replace brake pads?

以下是您需要新的刹车片的一些迹象：

• Wear indicator on vehicle dashboard.When the friction material on the brake pads is worn to within 2 mm of the pad backing plate, replacement of the pads is necessary. Most newer cars today have electronics built into the brake pad. When the pad is at a point that it needs to be replaced, a symbol will appear on your vehicle dashboard’s instrument cluster. Consult your owner’s manual to learn what the symbol looks like.
  
• 刹车时高高的尖叫声。When the friction material on the pads is worn close to the backing plate, you may hear a squealing or squeaking noise as you drive regardless of whether you are applying the brakes or not. That squealing or squeaking noise is designed to make you aware that the brake pads are getting low and need to be inspected. If all of the friction material on the brake pad has been worn away, you will hear grinding and scraping noises when you apply the brakes. Pad replacement is mandatory at this point and the vehicle is unsafe to drive until corrected.
• 制动踏板搏动或车辆振动。随着时间的流逝，制动转子可能会产生过度的厚度变化（> .001英寸），轮毂上过多的跳动（> .002英寸），或者由于高工作温度而导致制动转子可能扭曲。如果存在这些缺陷，您可能会在制动过程中注意到刹车踏板或方向盘的脉动。如果转子具有上述缺陷，则需要新的垫子和转子重新铺面或更换。
• 车辆在制动时拉动或徘徊。If your car pulls to the right or left during braking, that could be a sign of a sticking brake caliper, misalignment of the suspension, and sometimes tire defects or uneven tire inflation from side-to-side. The mechanic who inspects your vehicle will determine if new brake pads alone will resolve the issue or if other repairs are needed.
• 现有垫子上的高里程。Regardless of whether any of the above brake system symptoms occur, every 10,000 miles a mechanic should measure the thickness of the remaining friction material on the brake pads and perform a thorough visual inspection of the braking system.
• 制动系统警告灯和/或维护提醒消息。如果您的制动系统警告灯曾经照亮，或者在驾驶员信息显示中出现与制动系统相关的维护提醒消息，请尽快检查和修理车辆。
