A left-hand brake assembly should be replaced with the correct side-specific assembly. Installing the wrong side can affect braking operation and adjustment.
- Check the Side: This is the left-hand assembly. Confirm whether you need left, right, or a pair.
- Check the Brake Type: This is hydraulic free backing, not electric brake style.
- Check the Axle Setup: Use only where a 10" x 2.25" brake and 4-bolt flange match your trailer.
