Today were looking at the Demco 10 inch marine brake assembly, part number 40715. This is the right hand side and the way we tell this is by looking at the brake shoe linings. The forward shoe will be smaller than the rear shoe or primary shoe. This is our single servo setup which means the wheel cylinder will have piston that will push out against the brake shoe creating a wedge effect inside the brake drum. This assembly mounts on a 4 bolt flange which is already pre drilled in the backing plate to sit on top of your 4 bolt flange studs. As initial setup, we use a star wheel adjuster to adjust the brake shoe linings out to create a light drag on the brake drum, then as the brake shoe linings wear, we can remove the grommet in the backing plate to adjust the star wheel out to keep that nice even braking.
When we couple the right hand side with the left hand side, we can create up to 3500 pounds in braking capacity. To measure our brake shoe assembly, we go from the width of the brake shoe lining to the other brake shoe lining and see we have 10 inches and then we can measure the thickness of the brake shoe which is 2 and . This assembly will fit a 10 inch by 2 inch hub drum assembly. This assembly is also set on a galvanized backing plate making it goof for marine applications. It also a fall away brake system which means there will be minimal drag when backing up making it a good application for trailers with braking couplers.
There you have it for the Demco 10 inch marine brake assembly part 40715.
