How to check the remaining thickness of brake pads
The brake pad is composed of three parts: steel plate, adhesive insulation layer and friction block. The way to check the remaining thickness of the brake pad is to observe the friction pad that acts as a deceleration friction force.
Method 1: Listen to the sound. If there is a slight sound of [iron rubbing against iron] when the brake is lightly squeezed, check it immediately. It needs to be judged that the friction plate has been used up and the film base has rubbed against the brake disc, or it is just friction The film contains hard spots only.
Method 2: Feel the strength. When the friction plate is about to disappear, our braking effect will be affected. At this time, more forceful braking is required to achieve the braking effect that can be achieved with a light weight. The braking effect in the first half of the journey is obviously weakened. I feel that my brakes are becoming soft and I can't stop. At this time, it is necessary to check whether the brake pads need to be replaced.
Method 3: Observe the grooves. Most of the brake pads will have small grooves, which are called wear indicators. When the brake disc is worn out and the small grooves are no longer visible, it is generally possible to replace it.
