Before replacing the brake pads, it is necessary to loosen the fastening bolts of all wheels by half a turn, but not completely. This can make it easier to loosen the wheel bolts by utilizing the friction between the tire and the ground. The vehicle lifting position is a specific part of the vehicle body that is used to lift the vehicle, usually located behind the front wheels and on the "beam" of the vehicle body in front of the rear wheels. Use a jack to lift the vehicle up.
The brake cylinder of the disc brake commonly used in vehicles is fastened to the cylinder bracket by two bolts, which are then fastened to the swing bearing by two bolts. When replacing the brake pads, simply remove the two bolts that secure the brake cylinder.
When disassembling brake pads, it is necessary to use sandpaper to clean the dirt on the surface of the brake pads and apply lubricating grease for easy disassembly. Next, use a ring wrench and socket wrench to unscrew the bolts that secure the brake pads and remove them. When installing a new brake pad, it is necessary to apply lubricating grease first, then install the brake pad in the corresponding position and fix it with bolts.
