  Q: Should metal lines and rubber brake hoses be checked frequently for leaks and external damage on Mazda B2200?

  A:

  Checking of rubber brake hoses and metal lines should be done regularly to ensure that there is no leakage and external damage as metal lines are likely to be crushed and kinked by the vehicle undercarriage and thus they slow down the flow of fluid and limit braking. The rubber hoses should be checked when there is a crack or scraping since it can form weak points that would break under the pressure. When unloading or unattaching lines, large amounts of dirt are to be avoided; clean joints and connections prior to dismantling with stiff bristle brush and clean brake fluid and seal the lines and ports as soon as they are opened. Prior to installation, new lines and hoses must be flushed with brake fluid in order to remove contamination. The negative battery cable should be disconnected and then lifted and stabilized before removing any wheel and tire assembly that may be required to access it. Wipe the space around the joints, put a catch pan on the joint, and employ two wrenches to unscrew the hose or the line. Unplug the other line or hose and shift the drain pan (where necessary) and place a back-up wrench to ensure not to destroy the fitting. Eliminate the retaining clips or brackets that contain the line. In case the brake system is left open over a long time, tape or plug up all the remaining clips and ports to ensure no contaminants enter. Installation To fit, use the end nearest the master cylinder, being careful to have both fittings turned correctly and to turn freely. The new line should not touch any part of another and the protective shielding or insulators are to be fitted back in their original places. Upon making sure that the hose does not kink or come in contact with any of the frame or suspension, use 2 wrenches to tighten each fitting, retighten any retaining clips or brackets and reattach the wheel and tire assemblies, before rolling the vehicle down. Reconnect the negative battery cable by first emptying the brake master cylinder reservoir and filling it with clean, fresh brake fluid that is of DOT 3 specification and then bleeding out the brake system.
