Picking Out Trailer Brake Assemblies that Have Bolt Pattern 2-7/8 inch by 2-7/8 inch

Question

Question:

Looking for left and right hand side electric trailer brakes that have a square bolt patter. 2 7/8 side to side and 2 7/8 top to bottom. 4.4k axles. Your website is incorrectly displaying k23-454-00 and k23-455-00 as square bolt patterns. This is incorrect. I know because I ordered them and on delivery realized that your description was incorrect.

The 2-7/8 inch square bolt pattern that you need is a very common bolt pattern for 4-bolt brake assemblies that are 10 inch in diameter. The # 23-454 that you referenced uses a smaller bolt pattern at 2-13/16 inch by 2-13/16 inch which was common for brake assemblies made before 2009. The # K23-478-00 that you also referenced does not use a square bolt pattern at all so what you'd really be in need of is # 23-27 for the right hand side and # 23-26 for the left hand side.

Actually, there's a little more to it than that. The magnets on the #K23-478-479 are a little different, but the primary difference is the mounting bolt pattern. On a typical 3500 lb brake assembly, the mounting studs will all be 2-7/8 inches…

We have a 4-bolt brake mounting flange #4-50 which has an inner diameter of 3.01 inches. This particular flange is meant for 12-1/4 inch brake assemblies usually found on 8K axles which are usually 3-1/2 inches in diameter.

Since the mounting holes of the Demco Coupler part #DM15931-52 are 1/2 inch in diameter you'd want to source 1/2 inch diameter bolts Grade 5 or higher. Go with bolts and nuts long enough to fit through coupler.
