The basic principle of the brake system of a car is actually the same as that of a bicycle. It uses friction to convert kinetic energy into heat energy, thereby reducing the speed of the vehicle. If there is friction, there will be loss. The brake pad in the automobile brake system is a vulnerable part and needs to be replaced regularly.

ReplacementAutomobile brake padsWe will use jacks, suitable socket wrenches, ring wrenches, screwdrivers, sandpaper, grease, etc. Some vehicles are generally equipped with tools, such as jacks and cross sleeves for tire removal; while some need to be purchased by yourself. All tools andAutomobile brake padsParts can be purchased through the Internet.

Find all the tools and parts and we can start replacing them.Automobile brake padsThe. We can loosen the fastening bolts of all wheels by half a turn without completely unscrewing them. Before the vehicle is lifted, it is easier to loosen the bolts of the wheels by using the friction between the tires and the ground, which is why we did this in the first step.

In the second step, we use a jack to jack up one side of the vehicle in the lifting position of the vehicle. The vehicle lifting position is a part of the body dedicated to lifting the vehicle, generally located on the body "beam" behind the front wheels and in front of the rear wheels. The lifting position of the vehicle generally has a large raised rubber pad, which can be easily touched by hand. We only need to lift the vehicle to the wheel where the brake pads need to be replaced slightly off the ground.

Then we can unscrew all the wheel bolts and remove the wheel. For some vehicles that use aluminum alloy wheels, due to the unique wheel structure, the wheel is still stuck on the swing bearing of the wheel after the bolts are removed. If we encounter the above situation, we can try to push the upper edge of the tire sidewall with our feet or pat the front and rear edges of the tire sidewall with our hands inward, which will help the tire to come out.
