I have had many new trailers many of them Keystone. I have had two trailers and now the current one from DAY ONE with weak brakes and was told the same thing from the dealer they will get better. They work and function properly but would only slow the rig down and would not even drag the wheels on gravel even after burnishing. The issue of the wiring being thin is not far fetched in my mind. If you watch the way the trailers are wired you may understand why. They have spools of wire hanging from the ceiling and pull down what is needed. If someone grabs the wrong spool or replaced the spool with the wrong gauge wire the brakes will be weak because the wire can not supply enough amperage or will bleed off the amperage due to heat build up. Trailers that go down the SAME assembly line are not even wired the same. Running new wire for the brakes maybe a cheap, safe, and easier fix. Just my 2$.
