Today were looking at the Demco galvanized marine brake assembly part number 18788. This particular assembly is for the left hand side, we can tell this by looking at the shoe lining. The lining in the forward shoe is smaller than the lining on the rear shoe or primary. This means we have the left hand side. Couple this with the right hand side and it will create 3500 pounds in braking capacity. This is a single servo setup so we have one wheel cylinder and one piston that well push out against our shoe to create our pressure needed to create braking.
This particular setup is a 10 inch by 2 and . And how we find that measurement is by measuring across the lining to get our 10 inches and then measuring the show width to find out 2 and . When braking in reverse, this setup should create 25 percent braking in reverse. For installation its setup for a 4 bolt flange. You can see the bolts are predrilled to setup for your axle.
Then youll need to make a manual adjustment with the star wheel to push the brake linings out against the brake hub drum assembly. You want a light drag on your initial setup, then as the brake linings wear down, youll need to use the star wheel again to adjust the brake linings out but this can be down through the access hole here in the backing plate. And there you have it for our Demco galvanized 10 inch marine brake assembly, part number 18788.

Like the assembly being galvanized to last longer and already assembled. Being labeled for left and right is a nice added touch, but not necessary with single piston cylinders. I added a flush kit to my trailer and had to drill a hole through the plate to add, not a problem. 432696
So happy i found etrailer. They had the quality parts i had been looking for at a great price. I am equally happy with the speedy free shipping. I recieved the brake assemblies and installed them in less time than it took to locate them. Thank you. You will be my go to trailer parts supplier for all future parts. I have 5 different trailers and am sure i will require your services. Robert K. 390839

When I realized my brakes were in need of repair and no local shop worked on trailer brakes I decided to do it myself. With the help of the etrailer folks I had a new set of brakes and was ready for another fishing season. Great products, they do what they say and great customer support. 333472
These worked great. Much easier to replace the whole assembly like this, than replacing all of the original rusted out components. These are galvanized, so they should last a long time. I'm using these for a boat trailer for a 21 foot fiberglass euro styled V8 powered pleasure boat that weighs about 3000 pounds. 313288

"great product low price" quote is valid. bolted right up. Note: I have a boat, and the only thing missing on the backing plate is the half inch hole for my water flush out that was on my old ones, had to drill one next to the flange mount. I packed a little extra grease in the calipers too. 41921
