Kolasina Proportional Trailer Brake Controller for 1-3 Axle Trailers — Digital Display & Quick-Install

Whether you tow a small utility trailer or a multi-axle commercial load, the Kolasina 90160 is built to provide smoother, more predictable stops by sensing your vehicle's braking and applying trailer brakes proportionally. The unit combines an intuitive high-contrast screen, on-board self-diagnostics, and both snap-on and screw-in mounting options so it fits most cockpits and maintenance routines.

How does the Kolasina 90160 adjust braking for different trailers?

This controller uses proportional braking technology to match trailer braking force to how hard you press the vehicle brakes, rather than applying a fixed output. That results in gradual, coordinated deceleration and reduces jarring or premature trailer lock-up.

• Built-in motion sensor measures vehicle deceleration and adapts brake output in real time.
• Works across 1–3 axle trailers, suitable for light to heavier loads.
• Manual slider lets you fine-tune brake force instantly for unusual conditions.

What do I see on the screen and how does diagnostics help?

The high-contrast digital readout shows current brake settings and connection status clearly, even in varying light. Continuous self-diagnostics detect wiring or connection issues and present alerts on the display so you can correct faults before they affect towing safety.

• Real-time feedback on brake output and trailer connection state.
• Visual alerts for wiring faults or abnormal performance.
• Simple display that reduces guesswork during pre-trip checks.

How easy is it to install and position in my vehicle?

Installation is designed to be flexible: the Kolasina 90160 includes a snap-on quick-release bracket plus a traditional screw-in mount that swivels up to 180°, allowing horizontal or vertical orientation. The dual-mount approach speeds initial fitting and gives you a secure, adjustable placement tailored to your cab layout.

• Snap-on bracket for fast removal and reattachment.
• Screw-in bracket offers a permanent, vibration-resistant mount.
• 180° rotation to position the display for driver visibility.

What manual controls are available for on-the-road adjustments?

This model includes a manual slider control so you can instantly increase or decrease trailer braking force during unexpected situations, such as changing road grades or shifting loads. The slider complements the proportional mode, giving immediate, tactile override when needed.

• Slider adjusts brake intensity without navigating menus.
• Responds instantly for added driver confidence on hills or in traffic.
• Works alongside automatic proportional output for flexible control.

Who is this for: Drivers who tow regularly and need a dependable, easy-to-read proportional brake controller for single to triple-axle trailers—RV owners, landscapers, small haulers, and commercial users who want consistent trailer braking with simple installation and ongoing diagnostics. Kolasina backs the unit with a two-year warranty; confirm compatibility with your trailer wiring and controller footprint before purchase.
