Posted in Brake Hoses – How to Avoid Buying for Sale
Patron: WP company. When should brake hoses be replaced and what? In fact, it is impossible to determine by eye whether a given brake hose is of good or poor quality. A good wire is made from copper, cupro-nickel or steel tubes. Its outer diameter, wall thickness, bond shape and chemical composition of the material from which it is made are standardized.

For example, the outer diameter of the copper core should be 4,75 mm, and the wall thickness of the core should be at least 0,90 mm. Let's say we can measure the diameters with a caliper and look at the fitting, but what about the rest. The only way to avoid buying a low-quality cable is to check with the manufacturer. Does he have the appropriate certificates, does he correctly mark his cables (for example, computer printing along the entire length, where the company name is located, the quality certificate number, the manufacturer's batch number). If a company clearly labels its products, then we can be 100% sure that it will not sell us a cell, as in the event of a complaint, it may have serious problems. That is why I warn you against buying cables of unknown origin.
The so-called discounts are several zlotys cheaper than branded ones. In return, the customer receives a tube, the internal structure of which is not adapted to the loads in the brake system. The pressure in the brake hoses is 110-130 atm for touring and exceeds 180 atm for very fast, extreme driving. Chronicles of accidents report how such a game could end.
Worn brake hoses pose a safety hazard on the road. Both the pipe and the flexible pipe must have a constant cross section over the entire operating pressure range of the braking system. Otherwise, the work of the pressure forces (or part of it) will be directed to expanding the hose, and not to compress the brake caliper (or expand the brake cylinder), which is unacceptable.
