How to identify an improper trailer brake setting

This is just a quick post regarding the “evidence” you might need to confirm improper brake force setting on a trailer.

This is definitely “brake flat-spotting” from trailer tire lock-up. Higher force on relatively light loaded tires can cause this. Once there is a spot, the next time you hit the brakes the tire is more likely to stop at the same spot again.

Examples of flat-spotting on tires

Here are some examples of flat-spotting on tires removed from passenger cars. (Note: Your ST-type and LT-type tires will look similar.)

Did you take a close look at the tread surface when you did your last 2,000-mile tire “free spin” inspection, or when you repacked your wheel bearings on your trailer? It might be a good idea to check your brake settings every couple thousand miles.

Note: Vehicles with anti-lock braking systems rarely experience brake flat-spotting.
