Care information

To ensure optimal performance and extend the service life of your new trailer components, please follow these care guidelines after purchase:

  • Before installation, check all parts for shipping damage or missing components. Do not install damaged parts.
  • Always use correct tools and torque settings. Improper installation can lead to premature wear or failure.
  • For bearings, suspensions, and brake components, apply high-quality trailer grease before first use if not pre-greased.
  • Some parts (like brake assemblies) require a short break-in period to achieve full performance. Follow manufacturer instructions for best results.
  • Recheck fasteners, grease levels, and moving components after 100 miles of towing, then at regular intervals.
  • After exposure to water, road salt, or mud, clean and dry parts thoroughly. Apply anti-rust treatment if needed.
  • If storing unused parts, keep them in a dry, sealed container away from moisture and direct sunlight.

This brake assembly fits most standard 7,000 lb trailer axles that use 12" × 2" electric brakes with a 5-bolt mounting flange. Please verify your axle rating and brake dimensions before ordering. If you're unsure, send us your axle tag or hub information and we'll help confirm compatibility.
Yes. It is compatible with many standard Dexter, Lippert, Rockwell American, AL-KO, and other 7,000 lb trailer axles that use a standard 12" × 2" brake assembly. Always verify your axle specifications before purchasing.
Yes. This is a self-adjusting electric brake assembly, which automatically maintains proper brake shoe clearance during normal operation. This reduces maintenance and helps provide consistent braking performance.

PRODUCT OVERVIEW:

Replace a damaged or worn trailer emergency brake switch with the Jammy J-ELEC Trailer Breakaway Switch. Designed for trailers equipped with electric brake breakaway systems, this switch activates the trailer brakes when the pull cable removes the plunger from the switch during an accidental trailer separation. 

The J-ELEC includes a 48" coated steel pull cable, 45" wiring leads, and a zinc steel mounting plate for installation on the trailer frame. One switch lead connects to the breakaway power source, while the other connects to the trailer brake circuit, providing the electrical connection required for the breakaway braking system.

A single-screw mounting design provides straightforward installation and allows the switch to be positioned near the front of the trailer where the pull cable can connect to the tow vehicle. The J-ELEC can be used as a replacement breakaway switch or as a component in a new trailer electric brake breakaway system.
