Replacement of brake hoses

Four brake hoses are used on a car: two (rear) for connecting pipelines to the working cylinders of the rear brake mechanisms and two (front) for connecting pipelines to the working cylinders of the front brake mechanisms.

You will need: key «at 17» …



…special wrenches for brake pipes «at 11», «at 14», pliers.

Note. Always use special wrenches to loosen tube nuts, as the nuts are overtightened and usually corroded, as a result of which, when using ordinary wrenches, the edges of the nuts are crushed.

Note. Operation is shown using the front hose as an example. The rear hoses, which have a similar design, are replaced with almost the same methods.
