3. Adjust linkage according to manufacturer's specifications if misaligned.
4. Reassemble any removed components.

4. Replace Brake Switch (if necessary)

Sub-steps:
1. Locate the brake switch, typically found near the brake pedal assembly.
2. Disconnect the electrical connector from the faulty brake switch.
3. Remove the old switch by unscrewing it from its mounting position.
4. Install the new brake switch and reconnect the electrical connector.

5. Reconnect Battery and Test
