I noted that using a longer rubber brake hose has a marginally negative effect on the hydraulic system relative to stock. I have also noted that a series of such marginally negative swaps can have a greater cumulative negative effect on the system's performance. A longer brake hose here, a smaller m/c there, calipers not designed to work with the m/c here, rust in the brake lines there, all combine to degrade the system's performance. The idea with an older car is to improve its performance. Safety should always come first. Newer cars on the road are smaller, lighter, and have front and rear anti-lock brakes. An older car is at a comparative disadvantage with the stock brake system working perfectly. Why make that worse? Even a minor fender bender is to be avoided since parts can be hard to find, especially in Chile. Maximizing the performance of the brakes just makes sense.
Henry Ford said, "Thinking is the hardest work there is, which is probably the reason so few engage in it." Some people are mentally lazy.
