What are the symptoms of a damaged brake caliper?

The symptoms of a damaged brake caliper include: 1. Oil leakage at the connection between the caliper and the oil pipe; 2. The brake pedal feels soft. The maintenance methods for brakes are: 1. High-temperature protection to prevent corrosion of the brake system and avoid the brake pads seizing due to high temperatures; 2. Clean oil stains from the brake discs and brake drum components to ensure good heat dissipation of the brake discs; 3. Regularly replace the brake fluid; 4. Periodically check the thickness of the brake pads or brake shoes. The function of the brake is to reduce speed or stop the vehicle. Its working principle involves converting the kinetic energy of the moving vehicle into heat energy through friction between the brake pads and the brake drum, as well as between the tires and the ground, thereby slowing down or stopping the car.
When I encountered a damaged brake caliper, the entire driving experience instantly became terrible. That time driving down a slope, I felt much more resistance on the brake pedal than usual, as if it wasn't pressing down smoothly, and the car slightly veered to the right with a continuous squealing sound from the tires. After stopping to check, the brake disc was so hot it burned to touch, and I realized the caliper might be seized or leaking. The most dangerous aspect of this issue is the severe reduction in braking performance—in an emergency, the car might not stop at all, significantly increasing the risk of rear-end collisions or loss of control. The caliper is essentially the component in the braking system that clamps the brake disc. Once it fails, it either can't clamp tightly or won't retract, causing excessive drag, overheating, and fuel consumption. Prolonged issues like this could even damage other parts. So, I immediately went to the repair shop to replace the caliper. I also want to remind everyone: if you notice unusual noises or imbalance when braking, never ignore it—safety should always come first.
If the brake caliper malfunctions, the most common issue is unresponsive braking. As someone who frequently works on cars, I know there's a piston inside the caliper that pushes the brake pads to clamp the rotor. If the piston seizes or the seal leaks fluid, it can cause uneven braking force. Symptoms include one wheel dragging more noticeably, causing the car to pull to one side, while the brake rotor overheats, becomes scorching hot, or even smokes. During high-speed driving, the braking distance significantly increases, and sometimes a harsh metallic grinding noise can be heard. If there's a fluid leak, you might spot small oil stains on the parking spot. If not repaired promptly, the entire braking system can be affected. If the caliper completely seizes, the tire may lock up, potentially leading to a rollover. Therefore, at the first sign of these symptoms, it's crucial to inspect and replace the faulty parts as soon as possible to avoid major trouble.
A damaged wheel cylinder directly threatens driving safety. When it fails, the braking efficiency is significantly reduced, such as requiring more force on the pedal but the car still doesn't stop, and the vehicle may pull to one side and lose control. Even worse, if it gets stuck and doesn't release, the wheel may drag and overheat, potentially causing a fire. Timely detection can save lives.
