Question:

I’m looking for a complete trailer brake line kit for my 26 foot boat trailer. It’s a Marine Trailers Inc. model 2678TBH with tandem axles and hydraulic surge brakes. I measured the lines and it looks like 20’ from master cylinder to first T. Axles have the flex hose along with 6’ and 1’ solid lines to wheel cylinders. Do you have a complete kits to do the whole brake line job.

Hey Robert! We do have complete brake line kits. The DeeMaxx Hydraulic Brake Line Kit # DE57SR will work well for your setup. This has a 20' main line, 3' line, two 6' lines, and two 18" lines. It comes with fittings and everything else you need as well. I went ahead and attached the complete contents below, you can also see them on the product page.

Where are you headed next with your boat once the get the brake lines replaced?
