  Q: How should Brake Line components (metal lines and rubber brake hoses) be checked and maintained to ensure proper braking function on Mitsubishi Diamante?

  A:

  Brake hose lines made of metal and rubber are required to be inspected regularly in case of leakage and external damages, where metal lines are very likely to be crushed and kinked beneath the vehicle, which may limit the flow of fluids and the ability to brake. Rubber hoses should be checked on cracking or scraping since this could form some weak points that could break when pressure is applied. Removal and disconnection of lines require extreme cleanliness, all connections and joints must be cleaned prior to disassembly, and lines and ports must be plugged as soon as open. Brake fluid should be emptied into new lines and hoses before it is installed. To take off a line or hose, remove the negative battery cable, lift and support the vehicle, and take off any required wheel and tire assembly to do so. Wipe up the surrounding of the joints, put a catch pan under, and with two wrenches, unscrew the hose or line. Unplug the other side, shifting the drain pan, as necessary, and insert a back-up wrench to prevent damaging the fitting. Loose retaining clips or brackets that hold the line. In case the brake system is going to stay open, tape or plug some left-over clips and ports to prevent entry of contaminants. To install, begin with the new line or hose at the end most distant to the master cylinder and make certain to thread both fittings. The new line should not touch any other parts, and should be at least 1/2 inch clearance to steering column and moving parts, with any protective shielding or insulators replaced. Fit any fitting with two wrenches, re-fit any retaining clips or brackets and where possible re-fit the wheel and tire assemblies before lowering the vehicle. Before reconnecting the negative battery cable refill the brake master cylinder reservoir with clean brake fluid that is of DOT 3 specifications and properly bleed the brake system.
