How to Solve Brake Lock on a Van?

Floor the accelerator until the rear wheels start rotating. Gently tap the brake drum with a hammer to loosen the connection between the drum and brake shoes. Brake lock typically occurs during rainy days or after car washing, when rust easily forms between the inner surface of the rear brake drum and the brake shoes, causing them to seize.

I've experienced the issue of brake lock-up in a van. It happened just last week while I was on a delivery run. Suddenly, I felt the front right wheel jam and almost caused a skid. It was probably the brake pads sticking to the disc without releasing, possibly due to rust from rainwater or lack of maintenance. I calmly pulled over to a safe area, turned on the hazard lights, and tried gently rocking the van back and forth to loosen it a bit. But since the problem wasn't completely resolved, I had to call a tow truck to take it to the repair shop. The mechanic checked it and said the caliper piston was stuck. After lubricating it and replacing the brake pads, everything was fine. I recommend regularly spraying some anti-rust agent on the brake system. Vans carry heavy loads and have small brake clearances, so it's best to service them at least every six months to avoid embarrassing breakdowns and costly towing fees.
