How do you adjust the handbrake on a Vauxhall zafira?

To adjust the handbrake on a Vauxhall Zafira, first, ensure the vehicle is on a flat surface and the wheels are chocked. Locate the handbrake adjustment nut beneath the center console; it typically requires removing the trim to access it. Turn the nut clockwise to tighten the handbrake or counterclockwise to loosen it, ensuring that the handbrake lever has about 5-7 clicks of resistance when applied. Finally, test the handbrake's effectiveness before reassembling any removed trim.
