VEVOR Electric Trailer Brake Assembly, 12" x 2", 1 Pair Self-Adjusting Electric Brakes Kit for 7000 lbs Axle, 5-Hole Mounting, Backing Plates for Braking System Part Replacement (1 Right + 1 Left)

Based on the product information, it does not seem to explicitly mention whether mounting hardware or brackets are included.

While the product description doesn't mention anything about manual adjustment, it does state that the brakes are self-adjusting. However, customers appreciate the easy installation.

I did not find any information about compatibility with surge brake systems in the product description or customer reviews.

The kits do not come with wiring for the trailer

These fit the 7000 lb axle with 12 x2 drums and 8 lug bolt pattern

If it has 7000lbs axles.
