Why is the handbrake indicator light on?

[ElianaDella]

Here are the reasons why the handbrake light is on: 1. The handbrake is not fully released: The handbrake is not truly disengaged; 2. Low brake fluid: Insufficient brake fluid, with the fluid level below the safety line; 3. Brake pulling: If the handbrake light is on and accompanied by brake pulling, it may be due to uneven wear of brake pads or uneven force from the brake caliper. This situation requires immediate repair, as it can endanger driving safety. The handbrake, also known as the parking brake, functions by providing resistance to the car when parked, preventing it from rolling. It is equivalent to the parking gear in automatic transmissions, locking the drive shaft or rear wheels.
