Check the remaining thickness of brake pads
Brake pads are composed of steel plate, adhesive insulation layer and friction block. The way to check the remaining thickness of brake pads is to pay attention to the friction pads that play a role in decelerating friction.
Method 1: Listen to the sound, if there is a [iron rub iron] silk sound in the pinch brake, it should be checked immediately, and it needs to be judged that the friction sheet has been used up, resulting in the friction base rubbing the brake disc, or just the friction sheet contains hard points.
Method 2: Feel the strength, when the friction sheet is about to disappear, our braking effect will be affected, at this time, we need to brake harder to achieve the original very light braking effect, the first half of the braking effect is significantly weakened. Feel their brakes become soft, there is a point to stop, at this time to check whether the brake pads need to be replaced.
Method 3: Observe the groove, most brake pads will be distributed with small grooves, known as wear indicators. When the brake disc has been worn out of sight of the small grooves, it can generally be replaced.
