Locate the handbrake adjustment nut. It is located on the underside of the car, near the handbrake lever.
Adjust the nut by turning it with a wrench. Turning the nut clockwise will tighten the handbrake, while turning it counterclockwise will loosen it.
Test the handbrake by pulling it up and releasing it. The handbrake should hold the car securely in place when pulled up fully.
Repeat steps 2 and 3 until the handbrake is adjusted to your liking.
Warning: Be careful not to over-tighten the handbrake, as this can damage the handbrake mechanism.
