Do Brake Lines Have to be Equal Length for them to Activate Brake Assemblies Equally

Question:

The diagram for this hydraulic brake line kit shows the line from the actuator to the midpoint of the trailer but then a 19 inch line to one side and a 66 inch line to the other which tells me it has to be run down one side and the longer line takes it to the other side. Doesnt this configuration cause unequal braking pressure from one side to the other? Thank you

Hydraulic pressure does not apply more braking to the closer brake lines than the ones further away. The pressure is equal across the entire system at all times so the braking would be equal regardless of one set of brake assemblies having shorter lines than the other.
