What causes the brake caliper not to retract?

The brake caliper not retracting could be due to not changing the brake fluid for a long time, causing internal rust in the brake caliper, or poor precision of the caliper leading to insufficient piston retraction. It might also be caused by a blockage in the brake caliper pipeline, requiring replacement of the brake fluid or related components. Dirt causing sticking: Check if the piston in the brake caliper is sticking due to dirt. Another possibility is that the guide pipe fixing the brake caliper is stuck, preventing the caliper from retracting. In this case, remove the brake caliper and polish it with fine sandpaper. Internal rust in the brake caliper: Not changing the brake fluid for a long time can cause internal rust in the brake caliper. Apply grease to the outside of the fixing screws of the brake caliper and suspension, then reassemble and polish with fine sandpaper. Poor precision of brake pads: If the brake pads have poor precision or are too thick, the piston may not retract fully. Before replacing the caliper, disassemble the new caliper completely, clean off the protective oil applied before leaving the factory with carburetor cleaner, and then apply medical Vaseline to the entire caliper cavity and piston before reassembling.

What is the reason for the clicking sound when stepping on the brake?

The reason for the clicking sound when stepping on the brake is the normal activation of the ABS. The working process of ABS involves a cycle of locking and releasing, keeping the vehicle in a state of intermittent rolling near the critical lock-up point. When the ABS is triggered by a sudden brake application, it produces a clicking sound, which is a normal phenomenon. In this situation, firmly pressing the brake pedal to the floor is sufficient. The function of the car's braking system is to reduce speed or bring the vehicle to a stop. Its working principle relies on the friction between the brake pads and the brake drum, as well as between the tires and the ground, converting the kinetic energy of the moving vehicle into heat energy through friction, thereby slowing down or stopping the vehicle.
