Flexible brake line

Re: Flexible brake line

well I will throw my . 02 in. The automotive industry uses steel lines with flex connections for a very good reason, its called pressure expansion, then breaks are used the fluid pressure will cause a flex line to expand and you lose breaking power, now can you use flex lines , of course, but that's why its normally use at movement points. and why steel is used ever place else, and why copper was replaced by steel copper will split under pressure, Just a bit of information to conceder.

If you want to buy a ballast for a light, it is usually more than the whole new light fixture.

The price of the ballast didn't change that much though... just the price of the light has gone way down. I don't see a problem in that.

copper was replace with steel because copper is 4x the cost of steel, not because of pressure. they both have a ridiculously high pressure rating in small diameters (well in excess of what the brake system can generate). Aluminum can be used as well, however that is much higher corrosion issues than copper or steel.

The automotive industry also uses inexpensive reinforced rubber because it is cheep, much cheaper than braided stainless. The flex lines are to allow intended and controlled movement. The spiral coil near the master cylinder, or the long sweeping p-bend near a termination is to allow for minor movement from expansion, pressure, and thermal changes.
