Before ordering

Do not use the 3,500 lb four-bolt brake family just because a backing plate looks similar. The 296651 / 296652 assemblies have five-hole mounting patterns. The manufacturer specifies black-wire magnet kit 136447 for its 12-inch electric brakes; another company's similarly numbered magnet is not automatically the same part. This page links complete Lippert brake assemblies but does not represent a magnet as available under a different manufacturer's number.
