So, when returning to the parking lot last night, I noticed that I broke a break line on my trailer. A small metal tube about the size of a coffee straw is broke, its supposed to be attached to a rubber tube and then the brake its self.. I assume I can just replace said small metal tube.. but have no idea how to bleed the system with new break fluid. The part broken goes from a coupler that has a “T” and is the smaller hose running to he wheel. The other hoses in the T go to the other wheel, and the front of the trailer. Or, since I am a mechanical I D I O T , should I bring this to a professional.. and if so, how much will this cost approx?
