This activates the mechanical linkage inside the coupling, which pulls the brake cables and applies the trailer's brakes automatically. The harder you brake, the more braking force is applied to the trailer – providing smooth, proportional braking without requiring electric brake controllers.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAutomatic mechanical brake actuation – no controller needed\u003c\/li\u003e\n\u003cli\u003eProportional braking based on deceleration force\u003c\/li\u003e\n\u003cli\u003eFits standard 50mm tow balls (AK301 coupling head)\u003c\/li\u003e\n\u003cli\u003eRobust construction for Australian conditions\u003c\/li\u003e\n\u003cli\u003eCompatible with AL-KO mechanical drum brake systems\u003c\/li\u003e\n\u003cli\u003eSuitable for top or bottom drawbar mounting\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eBrake System Compatibility:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWorks with AL-KO mechanical drum brake systems including:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAL-KO 1637 (160mm drums)\u003c\/li\u003e\n\u003cli\u003eAL-KO 2051 (200mm drums)\u003c\/li\u003e\n\u003cli\u003eAL-KO 2361 (230mm drums)\u003c\/li\u003e\n\u003cli\u003eOther AL-KO mechanical brake systems when properly configured\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eImportant Notes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSecurity clamp or lock sold separately (recommended for theft prevention)\u003c\/li\u003e\n\u003cli\u003eProfessional installation and adjustment required\u003c\/li\u003e\n\u003cli\u003eMust be properly adjusted for correct brake cable tension\u003c\/li\u003e\n\u003cli\u003eRegular maintenance and lubrication required for optimal performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhy Choose Genuine AL-KO Couplings:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe coupling is the critical link between your vehicle and trailer, and it controls your trailer's braking.
