Where is the fuse for emergency brake?

There isn't a single, universally located fuse for the emergency brake (parking brake). The system's components (like the brake lights which are used in conjunction with the emergency brake, the switch itself, and any electrical motors if it's an electric parking brake) might have separate fuses located in different fuse boxes within your vehicle.

To find the relevant fuse(s), you need to:

1. Consult your vehicle's owner's manual: This is the most reliable source. Look for sections on fuses, electrical systems, or the parking brake. The manual will specify the fuse box locations and the fuse assignments.

2. Locate your vehicle's fuse boxes: Most vehicles have one or more fuse boxes, often under the hood and sometimes in the dashboard or under the steering wheel.

3. Check the fuse box diagrams: The inside of the fuse box cover usually has a diagram showing which fuse controls which circuit. Look for fuses related to parking brake, emergency brake, brake lights (these often share a common fuse or circuit), or any related electrical components.

Without knowing the make, model, and year of your vehicle, it's impossible to give a more specific answer. Always refer to your owner's manual first.
