Last time I found that locked brakes were too dangerous, so I quickly pulled over to check. The BYD F3 often has brake lock-up issues, which I suspect are caused by rusted or stuck brake calipers or pads. After parking, gently pump the brakes—if they loosen, that's good; if not, try removing the wheel, spraying some brake cleaner to remove rust, and lubricating the slide rails to see if they release. If the brake fluid is too dirty or insufficient, it may also affect retraction. To check the fluid level, unscrew the cap of the reservoir under the hood. Avoid leaving the car parked for long periods to prevent rust. If parked for over a week, it's recommended to move the wheels slightly. If you notice abnormal noises or stiff brakes, stop driving immediately and take it to a repair shop to avoid damaging the rotors or pads. Safety first—don’t take it lightly. I often share this process with my neighbors, and it’s quite practical.

When I encountered brake lock-up, I handled it myself. After removing the wheel, I inspected the brake disc and caliper, usually finding rust on the slide rails or brake pads stuck in position. With gloves for protection, I applied lubricating grease to the slide rails and gently tapped the caliper to loosen the components. If there are deep grooves on the disc, consider resurfacing or replacing the pads, ensuring the correct model is used. After repairs, test the brakes by pressing them a few times to confirm normal operation before driving. I routinely check the brake pad thickness monthly and clean dust buildup to prevent sticking. On the BYD F3, maintaining the brake system is straightforward—don’t wait until problems escalate. Emergency methods include jacking up the car and attempting to rotate the wheel; if unsuccessful, use tools for quicker lubrication. Always wear gloves for safety to avoid hand injuries.

When brake lock-up occurs, it's really nerve-wracking. I recommend stopping the car safely immediately and not moving it. Possible causes include caliper pistons not retracting or blocked brake lines. Check if the tires rotate freely and try gently pressing the brakes to test for looseness. Regular maintenance is essential: replace brake fluid, clean caliper rust, and avoid water ingress during car washes leading to rust. If you're not skilled in repairs, don't risk driving forcefully; seek professional shop services for efficiency and peace of mind. Maintain regular maintenance habits.
