This replacement breakaway cable is designed for trailer emergency brake systems using a cable-and-pin style switch. When the trailer separates from the tow vehicle, the cable pulls the pin from the breakaway switch, triggering trailer brake activation. It is a direct replacement type part for maintaining proper breakaway system function on electric brake trailers.

R&P Service Insight
The breakaway cable is one of those small safety parts that matters only when everything goes wrong. If the trailer ever separates, this cable is what triggers the switch and tells the trailer brakes to apply.

Compatibility: Universal fit for most trailer breakaway systems using a cable-and-pin design.
Vehicle / System Fit: Required on trailers equipped with electric brakes, including many utility, enclosed, and equipment trailers.
Installation Notes: Attach the cable independently to the tow vehicle and do not loop it through the safety chains. Verify the cable length and routing allow proper pull action without dragging or snagging.
Performance Insight: This cable is the trigger mechanism for emergency breakaway braking. When pulled, it activates the switch and applies maximum trailer braking power immediately.
R&P Repair Insight
Breakaway cable replacement is usually straightforward, but the safety function depends on correct routing and proper switch operation. A damaged cable, missing pin, or incorrect attachment point can leave the trailer without the intended emergency brake trigger.
- Switch Check: Confirm your existing breakaway switch uses a compatible cable-and-pin design.
- Cable Check: Replace frayed, kinked, corroded, or damaged breakaway cables promptly.
- Post-Test Check: After testing, make sure the pin is fully reinserted and the trailer rolls freely.
