Can 7 x 1-1/4 Inch Electric Brakes be Used with Drums for 7 x 1-3/4 Hydraulic Brakes
Updated 05/05/2020 | Published 05/22/2017
Question:
I am currently redoing my boat trailer and putting a wooden deck on it . I junked the boat. My question is that it currently has 7x 1 3/4 surge brakes on it . Will these electric brakes fit and function properly. I know the pad is smaller but Im only trying to make it inspectable and legal for the road. My truck is heavy enough that the reduced braking will not hurt me .

Expert Reply:
Like you said the 7 x 1-1/4 inch electric brakes # AKEBRK-2 will work with reduced braking. But there is another thing to consider and that is that not all brake drums are compatible with both electric and hydraulic brakes. In most cases it is one or the other. It may indicate this on your brake drums.
If you determine that you need to replace the hub and drum assemblies let me know the bearing numbers stamped into the sides of the inner and outer bearings along with the bolt pattern of the wheels.
