Method 1: Look at the thickness
The thickness of a new brake pad is generally about 1.5cm, and the thickness will gradually become thinner with continuous friction in use. Professional technicians suggest that when the naked eye observation brake pad thickness has only left the original 1/3 thickness (about 0.5cm), the owner should increase the frequency of self-test, ready to replace. Of course, individual models due to wheel design reasons, do not have the conditions to see the naked eye, need to remove the tire to complete.
Method 2: Listen to the sound
If the brake is accompanied by the sound of "iron rubbing iron" at the same time (it may also be the role of the brake pad at the beginning of the installation), the brake pad must be replaced immediately. Because the limit mark on both sides of the brake pad has directly rubbed the brake disc, it proves that the brake pad has exceeded the limit. In this case, in the replacement of brake pads at the same time with the brake disc inspection, this sound often occurs when the brake disc has been damaged, even if the replacement of new brake pads still can not eliminate the sound, serious need to replace the brake disc.
Method 3: Feel Strength
If the brake feels very difficult, it may be that the brake pad has basically lost friction, and it must be replaced at this time, otherwise it will cause a serious accident.
