Why Self Adjusting Brakes or Manual Adjust Trailer Brakes

Question

Question:

Looking to service the brakes on a camper trailer. The axles are a Dexter HF=85.50 SC=68.50, so Google tells me these are 7000# with 12inch x 2 brake assemblies??? * My wheels are 14inch if it matters. Looking at your parts line up, I see regular and self adjusting options. If these are fully interchangeable options, why would I not want the self adjusting version?? Could you please give me a couple of kit options? Thank you

Self-adjusting brake assemblies are the way to go like with the # AKEBRK-7-SA which do fit your 7k Dexter axles. The only real reason to go with manual adjust is really just cost. At one point the self adjusting models were much more expensive but now the cost is close enough that it's an easier choice to go with self adjusting.

I have included a link to a video on adjusting self-adjusting brakes. Basically there is a device on the adjustment wheel on these brakes that prevents the shoes from adjusting back inward. You have to sort of move that out of the way to be able to…

I have another option for you, but we do not have any 13" trailer wheels with offset to push the tire further from the frame, and do not recommend using any spacers as they can cause additional stress on the hubs which can wear out bearings and…

Answer 12

The wire gauge used in assemblies like the part #AKEBRK-7R-D is surprisingly thin at 16 gauge. The heavier gauge the wire the better. We recommend 10 gauge wire like part #10-1-1 (sold by the foot), for wiring up the brake output circuit. Since the…
