请问是什么问题？谢谢！ | q********g

如果刹车盘偏了，就是个不小的问题。
只能想到这个，你回头查了，上来说说。 | s***n

Here's why they squeal in reverse and what will help.
On the caliper you'll notice you have a spring on the top side of the
caliper. This spring lightly lifts the leading edge of the pads off of the
rotor surface. The leading edge is referred to as the edge of the pad that
the rotor is turning into, going forward this is the top edge. As you apply
the brakes in a forward motion, the pad is brought in contact at a slight
angle, not allowing the leading edge to touch |
