The rubber hoses of the steel brake lines should be inspected at a regular rate of about every six months, with the vehicle elevated and placed upon jackstands, to check cracks, chafing, leaks, blisters and other damage in the hoses, since they are vital components of the brake system. A check will be conducted properly with the help of a light and a mirror, and hoses with traces of wear must be changed. To reduce wastage of fluid during replacement of any pipe/ hose, place the polyethylene over the top of the master cylinder reservoir before fitting it or screw a brake hose before clamping a brake hose and then plug or cap metal brake line fittings immediately after disconnection. Put any rag under any appropriate fitting to prevent any spilled fluid and when removing a flexible hose, unscrew brake line fitting and remove spring clip where the hose is attached. The fitting nuts should be unscrewed with a flare nut wrench, to prevent rounded off corners, and the fitting and the surrounding place should be cleaned. Where a component has a number of fittings, record the connections carefully in case it is removed. Replacing metal brake lines, replace with the correct parts not with copper tubing, and use prefabricated brake lines, which are sold by auto parts stores and have to be curved to the right shapes. Make sure that the new line is well bracketed with a clearance of moving or hot parts and should not overtighten fitting nuts. Ensure that the pipes and hoses are properly laid without kinking and fixed in the supplied clips or brackets. Once installed, drain the hydraulic system by removing the polyethylene sheet in the reservoir, wash and dry any spill in the hydraulic system with water and leaks.
