Brake Hose


Brake hose fittings have either female threads, male threads, or banjo fittings. Banjo fittings, named because they resemble a banjo, allow brake fluid to make a 90° turn in a tight space.

Brake fluid goes into the banjo fitting and exits through a hollow bolt. A copper gasket is used to seal both sides of the fitting.

Always use two wrenches. the second wrench holds the female part of the fitting. if the female fitting is allowed to turn when the male flare fitting is turned with a wrench, the line will become kinked.

Many brake hose failures can be traced to errors made in the original installation or repair of the hose. Hoses twisted into place become stressed and are prime candidates for leaks and bursting. Most manufacturers now print a natural lay indicator or line on the hose. By making sure this line is not spiralled after fittings are tightened, you can ensure the hose is not overly stressed. Also, always use a hose of the same length and diameter as the original during servicing to maintain brake balance at all wheels.
