Hydrastar Mounting Bracket

Trailer Braking

Trailer braking is the most critical function of towing. Therefore, electric braking provides the ultimate control and safety.

HydraStar® claim to have the quickest response time and the lowest current draw of any brake actuator on the market.

Note: Proportional controllers do not supply 100% of the voltage when the vehicle is not moving. Your car must be driving for the Hydrastar® to work correctly.

To test the braking system, pull the pin on the breakaway kit to assist you in bleeding the system of hydraulic oil.

What is a Breakaway Kit

A breakaway kit applies brakes for not less than 15 minutes if the trailer disconnects from the tow vehicle.

Couplemate recommends the use of a stainless braided SAE hydraulic hose. Bundy tube or steel tube can become damaged and, as a result, restricts the flow of brake fluid.

The braided hose is flexible and poly-coated for long life. Copper tube olive ends with short brass locking nuts.

Equipment like Alko and Trojan caliper requires an olive adaptor nut with a copper washer to properly seal hydraulic connections.

Finally, a stainless braided hydraulic hose is a good investment to use to connect your Hydrastar to the hydraulic calipers.
