Why do the rear brake pads wear first?
Why do the rear brake pads wear first? The damage level of brake pad is related to its application frequency and bearing capacity. In the design of the vehicle, the inertia force of the brake pedal is considered to rush forward. The rear wheel drive brake responds first to the rear brake, and the front brake pad is effective later.
The front brake pad can completely stop the vehicle after the brake pedal is applied at low speed. The response of the front brake pedal is faster than that of the rear brake pedal. Under fast and safe driving, the emergency brake pedal vehicle may have a headstand under the inertial force. It is reasonable that the damage of the front brake pedal is much less than that of the rear brake pedal.
The net weight of the car body of the front drive is basically in the front, and the driving force of the car engine is provided in the front. Naturally, the front wheel drive brake responds first, and the rear brake pad is effective later. When driving the brake pedal safely in low gear, the front brake pad can make it stationary, and the rear brake pad only participates in movement. Naturally, the response of the front brake pedal is faster than that of the rear brake pedal. The net weight of the front wheel drive avoids the forward impact of the vehicle. The front brake pad is damaged much more than the rear brake pedal.
The replacement cycle of vehicle brake pads is not stable, which lies in the application frequency and bearing capacity. Most of them need to be replaced once for safe driving of more than 30000-60000 kilometers. When the brake makes a sharp sound, the brake pads are damaged to about five mm (mm), and the instrument panel in the vehicle reminds the brake pedal of frequent faults, the problem is almost the data signal to replace the brake pads.
