What causes the handbrake to get stuck when pulled up and unable to release?

It may be due to failure of the handbrake ratchet mechanism. Here is an introduction to automotive handbrakes: 1. Overview: The parking brake, commonly known as the handbrake, functions to provide resistance when parking, preventing the vehicle from rolling. The parking brake, whether manual or the parking gear in automatic transmissions, locks either the driveshaft or rear wheels. The parking brake exerts significantly less force compared to the service brake, just enough to prevent rolling on slopes. 2. System: The electronic parking brake system integrates temporary braking during driving with long-term parking braking functions, achieving parking brake control through electronic means.
Last week, my car had the same issue—the handbrake got stuck after being pulled all the way up. The mechanic said it was most likely due to water freezing inside the brake cable sleeve, a common problem in cold winters. If it happens right after washing the car or driving through water, it’s almost certain the cable is frozen. They used a heat gun for twenty minutes to free it and suggested I avoid pulling the handbrake all the way in the future—just go up to 70%. Also, remember to press the button and wiggle the lever up and down a few times when releasing it to shake loose any ice debris. However, if it gets stuck in the middle of summer, it might be debris stuck in the ratchet groove, requiring disassembly to clean the track.
