It is confirmed for Bukhanka Classic (2.4L \u0026amp; 2.9L) and Hunter \u0026amp; 469 (2.4L \u0026amp; 2.9L) models. Mounted in the master cylinder or distribution block, the switch activates the brake lights as soon as hydraulic pressure builds in the brake lines, ensuring immediate and reliable response.\u003c\/p\u003e\n\u003cp data-start=\"749\" data-end=\"1122\"\u003e\u003cstrong data-start=\"749\" data-end=\"789\"\u003eWhy choose this brake signal switch?\u003c\/strong\u003e\u003cbr data-start=\"789\" data-end=\"792\"\u003eThis OEM-type switch is a simple and durable solution compared to pedal-mounted microswitches.
