Adjusting the handbrake on a BMW requires precise tools and a clear method. Begin by assembling a flathead screwdriver, socket wrench, and a torque wrench for security. The parking brake mechanism lies in the center console; locate the adjustment area beneath the handbrake lever. Use a socket wrench to adjust the tension screw carefully, ensuring both rear wheels attain equal tension to avoid imbalanced braking.
