Why does fuel consumption increase after replacing brake pads?

Brake caliper not retracting, apply some grease on the caliper pins. Maintenance: Brake pads need to be replaced every 3 to 6 kilometers. In a vehicle's braking system, brake pads are the most critical component, as the effectiveness of braking entirely depends on them. Brake pads are generally composed of friction material, steel backing plate, and adhesive heat insulation layer. The steel plate should also be regularly coated to prevent rust. When the brake pad indicator light comes on, it indicates that the brake pads need replacement. If this occurs, they should be replaced promptly. Brake pads also need replacement if their thickness is less than 0.5cm. Braking working principle: It primarily relies on friction. The vehicle uses the friction between the brake pads and brake discs against the ground to effectively provide sufficient stability and controllability in the braking system, thereby ensuring the driver's safety.
