What Causes the Friction Sound from the Rear Wheels?

[DiGraham]

The reasons for the friction sound from the rear wheels are: it may be due to hard spots on the car's brake discs, or a malfunction in the car's brake separation pump, causing the calipers to fail to separate from the brake discs, or excessive wear of the brake pads. Brake Pad Maintenance: The effectiveness of a car's braking system is largely determined by the brake pads, which are crucial for the vehicle. Regular inspection and protection are essential. Under normal driving conditions, the brake pads should be inspected every 5,000 kilometers. This inspection should not only check the remaining thickness but also the wear condition of the pads, whether the wear is even on both sides, and if they retract smoothly. Any abnormalities must be addressed immediately. Brake pads should be replaced when their thickness is reduced to approximately 0.5 cm. Brake Pad Replacement: When replacing brake pads, it is best to use original equipment manufacturer (OEM) parts. This ensures the best braking performance and minimal wear between the brake pads and discs. After replacement, it is important to pump the brakes several times to eliminate any gaps between the pads and the brake discs.
